At PADT, “We Make Innovation Work.” But what does that really mean? We provide the tools and services that engineers need to design, test, and manufacture physical products. The list of services and products is long, because doing product development is complicated and requires many skills and resources. So in the end the biggest problem we have from a marketing standpoint as a company is making sure all of our customers know about all the things we do.
If you have looked at our primary website, you can see the problem. It is easy to get lost. So we thought we would take a different approach and publish a series of blog posts on each of the unique tools or services we offer. We will link back to the website or external websites where appropriate, focusing on helping you, our customers, just get to know us better.

Posted on July 2, 2018, by: Eric MillerAs engineers, we spend most of our time trying to get geometry we create in a computer out into the real world as a physical part. But sometimes, we need to go the other way. We need to get real geometry into a computer. Once there we can measure it accurately, modify it, simulate it, or use it as a reference to design something that connects to it. There is a lot of power in being able to quickly and accurately digitize objects. Here at PADT we make that power available to our customers through our Scanning & Reverse Engineering Services and through the sale of the same tools we use to our customers so they can bring scanning in-house. In particular, we represent high-fidelity scanners and software from ZEISS and Geomagic.
Creating Accurate Digital ModelsOur own experience with scanning taught us the hard way that the key to creating accurate digital models was outstanding hardware and powerful software. There are a lot of solutions that take shortcuts to "make it easier" or to keep cost down. We tried those, they didn't work. That is why we settled on ZEISS and Geomagic tools because they do work, and they work well. The process of digitizing geometry is simple: put the part in front of a scanner, scan it, and get a point cloud. The reality is that the right hardware and software determines if you will spend days to get gigabytes of useless data or if you spend a few hours to get a useful and accurate computer model that you can work with.
Structured Light ScanningThe scanners from ZEISS and Geomagic both use a technology called Structured Light Scanning. Some also refer to it as Fringe Projection. The way it works is that you couple a precise light projector with a high-resolution digital camera. The projector projects a series of lines onto the part and the camera records how that pattern distorts. The pattern is varied to get more resolution. The part is also rotated or projector-camera assembly is moved around the part. Either way, light is projected onto the surface in a pattern, and the distorted pattern is recorded. Then some sophisticated math is used to turn how the pattern is distorted into a highly accurate collection of points across the surface of your part. That is the end result of Structured Light Scanning - millions of points that sit on the surface of your part.
World Class Scanning HardwareThe quality of the hardware used is key to success in this area. To be accurate you need a very precise projector, an accurate digital camera (called a sensor in this application) and world-class optics. Which is how we ended up working with ZEISS. Their optics are second to none, and they have developed or acquired the best projector and sensor technology in the industry. Combine that with their famous German engineering and quality processes, and you end up with a robust and accurate solution that is second to none.

Portable Laser Scanning with Touch Probe May Be a Perfect FitSome parts are too big for structured light scanning. Or sometimes you may want to measure a few locations on a larger part. For those situations, the ZEISS T-SCAN CS Handheld scanner is the perfect fit. It combines an optical tracking unit, a handheld laser scanner, and a touch probe to give you the flexibility you need to take measurements on large objects. The touch probe is especially useful for measuring key features and locations. View more about the T-SCAN CS here.
Geomagic Capture Scanners Deliver Portability and Cost SavingsMany of our customers needed a portable solution that cost less and was really only needed to get geometry into their CAD systems. We searched and found that the Geomagic Capture scanners from 3D Systems are a perfect balance between functionality and cost, delivering high value.
|System||Weight||Resolution||Min Field of View||Standoff Distance||Max Field of View|
|Capture||1.35 kg||0.11 mm||180 x 124 x 120 mm||300 mm||180 x 190 x 175 mm|
|Capture Mini||1.04 kg||0.08 mm||70 x 87 x 68 mm||157 mm||70 x 88 x 87 mm|
Proven Scanning SoftwareOnce the points have been captured, no matter how accurately that was done, they are useless if you don't have the right software tools. Geomagic 3D software and hardware tools are industry leaders for one simple reason: they work. For reverse engineering, inspection, scanning, cleaning up point clouds, or working with mesh-based geometry, no other set of solutions comes close to the capability and robustness of the Geomagic tool package. We use three packages:

Posted on June 4, 2018, by: Eric MillerThe development of medical devices is difficult. The regulatory challenges, quality requirements, and technical hurdles of dealing with the complex system that is the human body make the processes required to bring products for this industry to market unique and difficult. That is why PADT has a team in our Engineering Services department that is focused on one thing: Medical Device Development. If you read our article on Product Development Services or watched the flashy video then you know how we do product development differently. That our processes and staff are proven, that we are all about solving problems and using project management intelligently, all geared towards to deliver a complete solution. Every one of those characteristis is true for our Medical Device team as well, we just add more on top to give our customers the confidence to work with us on their product development. We sometimes get involved in projects all the way from defining specifications to coordinating with manufacturing. We also provide assistance at every step along the way: testing, concept modeling, trade studies, material evaluations, quality consulting, design for manufacturing, and testing to name just a few areas that we can help. That is one of the things that makes PADT unique in this particular industries. Most companies will only do the full product development, whereas we serve as an outside resource for the whole thing, or only where our customers need additional help.
Solving the Tough ProblemsThere are a lot of medical device design companies out there. We often get asked how we can stay busy in this industry, especially when we are not located in a hot-bed of device design and manufacturing like California, Boston, or Minneapolis. The answer is simple. Customers from those locations and other markets come to Tempe to work with us because we are good at solving the difficult problems. Most of this capability comes from the skill and experience of our staff. They know their stuff and they know how to systematically investigate and solve the most difficult problems. They also have access to advanced tools like 3D Printing and world-class simulation in-house. Combine this with solid project management and a well-provisioned lab, and you have a winning combination.
Understanding Medical DevicesThe other key requirement for anyone doing medical device product development is a thorough understanding of Medical Devices themselves. Every industry has its buzzwords and acronyms, but medical devices are in a category all their own. They are a bridge between the world of mechanical engineering and medicine, so they terminology and operating environment are different then say aerospace devices or consumer products. To work on medical devices you have to understand all the physics, manufacturing, software, and electronics that every mechanical device needs. You also need to understand biology and treatment. PADT's staff walks that fine line between the two worlds and often serves as a translator between the end user (doctors and nurses) and engineering, even within our customer's organizations.
Quality CentricQuality is the most important, and least understood, unique aspect of Medical Device Product Development. Any team attempting to bring a product to market who does not know ISO 13485 and the FDA requirements will fail. We also know that Quality is a tool, not a barrier. We understand the client's quality system and adapt our processes as efficiently as possible to get value from the entire quality process.
Let us Engineer your Medical Device InnovationsHere is a powerpoint we put together last year with even more information: Product development for medical devices is something we are just plain good at. Large corporations and startups come to PADT to because we get the job done. You can see some great case studies here that tell the story in the words of our customers. Reach out to us via email (email@example.com) or give us a call at 480.813.4884 and we can talk about how our team can help engineer your medical device innovation.

The fact of the matter is, to be blunt, that building, maintaining, and optimizing systems for high-performance computing (HPC) is different than any other part of the IT world. That is why most companies engaged in simulation who use HPC often struggle with their computers and networks, specially when they don't have protection from filtre de confidentialité VistaProtect to keep their work private. There is nothing wrong with their IT departments, they simply don't have the manpower or the experience to support HPC systems. And that is why PADT offers IT support services tailored towards the needs of simulation users. We bridge that gap between the unique needs of HPC for simulation and customer's existing IT infrastructure.
We started offering the fastest business internet for this service simply because customers asked us to. As part of ANSYS technical support duties, we kept getting calls from customers who were just not getting good performance out of some very expensive computer hardware. After looking into it we often found that they had the wrong hardware, it was configured wrong for HPC, or there was unnecessary overhead on the system. In each case, we got together with the customer's IT department and the users to understand the problem and implement fixes. In Hertfordshire IT Support Services you will find the best network support business in cyber security to manage any issue you might have.
PADT's IT team can offer a variety of services, including, but not limited to:
Focused on Performance
Most computer systems and the IT infrastructure that supports them, in the commercial world, are focused on security first, operating cost second, then performance. And these are the right priorities. But in the HPC world, those same systems and infrastructure have to be focused on performance, with robustness second. Security is important, but you solve that problem by isolating the systems and controlling access. PADT's IT team gets this and because we run a large HPC infrastructure for our own simulation consulting business, they know how to set things up right and keep them tuned for performance.
A Partnership Between Users, IT, and PADT
Our deep knowledge of scientific computing and the hardware it runs on is only one part of our success in this area. The other is knowing how to be that translator between IT and the users of demanding numerical software packages. We understand why IT can or can not open certain ports, and why the user needs those ports. We get the desire to establish a company-wide policy using remote drives that use RAID 1. We also know that doing that kills HPC performance. That starts the conversation on why users need local drives in RAID 0 for their number crunching.
The examples go on and on and involve memory, network fabric, different versions of MPI for each solver, and much more. Often times just being able to explain these issues in terms everyone can understand is the greater value PADT can add. And then our IT experts will be there with the customer's IT experts at 11:30 PM installing those GPU cards and configuring them.
The cold hard reality is that companies spend large sums on advanced hardware, software, and infrastructure. Why not spend a little more to make sure you are getting the most from that sizeable investment. PADT is here to help, to work with your IT and users, to get the most out of the tools you have.

Stratasys, The World Leader in Additive ManufacturingThere is one simple reason why Stratasys is the world leader in Additive Manufacturing systems and why so many of our customers keep buying Stratasys systems: They Work. The whole point of 3D Printing is that you can go from a computer model to a real part as quickly and easily as possible. Stratasys has created a complete set of hardware, material, and software to make that happen. For hardware, they offer two additive manufacturing technologies: FDM and PolyJet. FDM, or Fused Deposition Modeling, is the most common technology because it is reliable, accurate and builds strong parts. FDM was invented by Stratasys over 25 years ago and still forms the foundation of their product line. It is a layered deposition process that melts a variety of plastics that are then extruded through a nozzle to draw the shape of each layer. From the desktop MakerBot machines to the industry favorite FORTUS 900, there is a machine that works for every need. Recently, we have been selling a large number of F370's to new an existing customers. FMD systems come in a variety of sizes, speeds, costs, and most importantly, material options. And best of all, the majority of FDM systems come with Stratasys' patented soluble support material that makes support removal as easy as dropping your part into a cleaning system (many of which are made by PADT). If you need greater refinement, the ability to change material, or color, then PolyJet technology is your ideal solution. The power of PolyJet is that it uses inkjet print heads to deposit tiny dots of liquid material on a build layr. That material is then hardened with an ultraviolet lamp. What is cool is that you can have multiple inkjet print heads and therefore deposit a mix of material within a given layer. This allows you to make parts with very hard, or very soft material in the same build. Or, to mix clear and colors in the same build. Our customers use Polyjet printers to make everything from accurate medical models of organs to molds for plastic injection molding. No other 3D Printing technology is as versatile as the PolyJet machines from Stratasys.
The PADT Sales Experience
Lots of people sell 3D Printers. We know because we have been doing it for over fifteen years. And as the technology has become more popular, more and more people are getting into the industry. Our experience and technically driven sales approach is why customers keep coming to PADT when they have so many choices. Our sales team is not about this months sales goal. They are about building, and more often than not, growing our relationship with customers new and old. We are all about understanding what you really want to get done, and then finding the right combination of Additive Manufacturing system, accessories, and software that will make it happen. That expertise comes from the fact that we have been running a 3D Printing service since 1994. We know the real world of Additive Manufacturing. No other reseller can bring our expertise and experience to your aid.
Support that Goes Above and BeyondOnce you purchase a system, your journey with PADT hits full swing. Our engineers will help you install, train your users, and then be there when you need us for maintenance and repair. Or simply to answer your questions. We recently won a series of competitive situations where customers had a choice of who to hire to support their Stratasys systems. They chose PADT over other solutions for one simple reason: we know what we are doing and we really do care. Our team has driven through snow storms, stayed with machines late into the night, and personally shipped replacement parts just so they could get customer's machines back online and running as quickly as possible.
Talk to PADT about your Additive Manufacturing NeedsRegardless of what systems you currently have, or if you don't have any 3D Printing capability in-house, now is the time to talk to PADT. We have never had a better offering of solutions in terms of price, performance, and variety of capability. We are helping universities establish labs, Aerospace companies 3D Print hardware for launch vehicles, and consumer products companies shorten their design cycle. It may be time for you to upgrade or add a new material or technology. Or maybe you just need some accessories to get more out of the equipment you have. Regardless of where you are in your Additive Manufacturing journey, PADT is here to help you get more out of your investment.
Posted on February 28, 2018, by: Eric MillerWhen you think about manufacturing and PADT, you will most often think of Additive Manufacturing, or more generally 3D Printing. Although this new and exciting area of technology is the foundation of our Advanced Manufacturing department, it is only one part of what we offer. As discussed in the opening piece in this series, our manufacturing team also offers part scanning and reverse engineering services. What many people do not know is that our experts, often working with our product development team, also offer consulting services for all kinds of manufacturing. When it comes to getting parts made, a company needs to find the right manufacturing methods, the proper processes, the right vendor, and the right manufacturing plan to get their parts made correctly and cost-effectively. This is true if they manufacture and assemble in-house, if they outsource the entire process, or if they do a combination of building, buying, and assembling. PADT is a valuable resource that can help investigate options, provide advice on next steps, and even serve as a liaison between our customers and their suppliers and vendors. Whatever the product, whatever the manufacturing technology, and wherever the facility, PADT can help. Here are some typical examples of what we have done for customers. If you do not see what you need, no worries, contact us anyway and we can figure it out. Simply put, if you need help getting stuff made, we are here to help.
Finding Manufacturing SolutionsGetting products made can be hard. And pressures in most segments for greater performance in less volume for less cost are making manufacturing challenges more difficult every year. Many times traditional methods and processes that have worked in the past just can not get the job done. That is where PADT comes in to look at your needs with fresh eyes backed with a wealth of knowledge about different manufacturing solutions. Sometimes we help change the design and sometimes we change the process, and often we work with our customer to do both so that they can get their parts made.
Vendor Identification and ManagementMany customers come to us with a simple request: Find someone that can make this and help us get it made. They may not have the staff with the proper experience needed to find, qualify, and manage vendors. Or those people may simply be too busy. PADT's network of proven vendors combined with our project management expertise makes for a simple and single point solution for customers large and small. From supply chain, through inspection, to shipment, our team can take on the tasks you need to be done to make sure your products show up ready and to specification where and when they need to be there.
Injection Molding ConsultingThe most common type of consulting that we conduct for customers is helping them with injection molding. If they need a straightforward part with no technical challenges, then there are literally thousands of vendors that can do that job. But if the plastic parts they need have challenges, if normal injection molding suppliers have look at the parts and scratched their heads, that is when PADT can step in and solve problems. We can use our knowledge of plastic part design, our large network of expert injection molders, and proven problem-solving skills to find a way to get those difficult parts made in a timely and affordable manner.
Developing New TechnologiesSometimes, there just is not an existing way to get something made. There may be technologies that get close, but nothing that already exists in the right combination. That is when PADT's advanced manufacturing, simulation, and design skills can all come together to develop new technologies and processes to enable true innovation. From new material combinations to novel post-processing approaches, our team can bring in other experts and suppliers to find ways to push out beyond the leading edge of advanced manufacturing.
We Make Innovation WorkNo part of bringing products to market stresses the importance of making innovation work more than manufacturing. This is where all of the ideas and solutions come together to create a physical product. Every product is unique, and every product has unique manufacturing problems. That is why PADT's Manufacturing Consulting is called on by customers across industries to solve problems and find solutions. And that is why if you are facing manufacturing challenges, you should call on PADT to help you.
Posted on February 1, 2018, by: Eric MillerThe "D" in PADT stands for design. It has been an integral part of PADT's service offering since the company was started. Design, or more broadly Product Development, is the engineer process of defining, designing, testing, prototyping and transferring the manufacturing of a product. From concept to manufacturing, or any point in between, PADT's engineers can help with product development. Doing product development with PADT is about defining product requirements and then stepping the team through a proven process that iterates efficiently and results in working hardware that has been tested and verified. This approach works across industries. We have worked on products for golfing, designed the insides of an electric vehicle fast charger, designed and built an alpha-machine for semiconductor manufacturing, reconfigured the configuration of an avionics device, developed several medical devices through clinical trials, and tested the fittings on an artificial heart. We specialize in working with companies that have an engineering staff, but don't have the specialization or capacity need to complete a project entirely in-house. Our engineers become part of the customer's team and can work on specific tasks, a subsystem of the product, or complete the entire process. Regardless of the scope, it comes down to our providing our customers with experienced and capable engineers that can plug in where they are needed. There are four characteristics that set PADT apart from other design houses that help with product development:
We have been providing product development services since 1994. As of this post being published, we have 30 engineers onstaff and we have helped over 400 customers with their product development needs. Many of those customers choose to use PADT over and over again letting us design and test their products.
What sets PADT apart from most providers of design or product development is the fact that we are problem solvers. Product development is primarily the process of identifying problems and finding solutions. And that is what our engineers excel at and thrive on. We are brought in by customers because we can answer the tough questions.
It does not matter how experienced your staff is, or how amazing your tools and equipment. To be successful in product development you need to have a proven Project Management process. PADT's process has been developed over decades to provide a flexible methodology to ensure requirements are defined, that they are met on time. It drives the entire process to achieve deliverables on-time and on-budget with minimal customer oversight.
Project managers and design engineers work with simulation, test, software, and manufacturing engineers to address the needs of the complete product lifecycle. Almost every capability that is needed is available within PADT's walls, and a tested network of approved vendors fills in any missing needs.One of the best ways to understand these difference is to watch our video on Product Development here: https://www.youtube.com/watch?v=UM-hicIQiMk You can also review some of our great case studies:
|Satellite Messaging Device||Electric Vehicle Fast Charger||Tissue Expander|
|Smart Orthopedic Sensor||Ultrasonic Skin Treatment Device||Compact High Pressure Hydrogen Pump|
Posted on January 3, 2018, by: Eric MillerWhen we tell people that "We Make Innovation Work" one of the key ways that we actually make innovation work is through the sales and support of ANSYS Simulation Software. Few toolsets have changed the way products are designed and manufactured as the structural, thermal, fluid, electromagnetic, and multiphysics simulation programs written by ANSYS, Inc. Outside of the world of mechanical engineering, simulation is not as well known as 3D Printing, but in reality, it plays a larger role in product development with more users and a larger return on investment to companies that make simulation part of their process. If you are not familiar with simulation, it is a process where a mathematical model is constructed on a computer to represent the physical behavior of a product. Once the model is made, an engineer can do "virtual testing" on the model to understand, improve and optimize the design. The majority of innovative companies now make simulation a part of their product development process, and ANSYS is the largest provider of simulation tools. Customers choose ANSYS products for one simple reason, they deliver. ANSYS only does simulation, they are not a CAD or PLM company trying to add simulation. With close to $1 Billion in sales, and 2017 should cross that threshold, no other provider is as large either. They are the biggest provider because their software works. Many other companies offer much cheaper solutions, but time after time companies invest in ANSYS technology because they get their money back quickly in better products that get to market faster. PADT is not just a reseller of software, we are an ANSYS Elite Channel Partner who dedicates a significant part of our staff, over twenty people, to selling, supporting, and training around the complete ANSYS Product line. Our territory is the Southwestern United States; including Arizona, New Mexico, Colorado, Utah, Nevada, and Southern California. We have been setting the standard for win-win sales and outstanding support for over twenty years and have a worldwide reputation for technical excellence not just with ANSYS tools, but in how to efficiently use those tools to drive the design of products. Our sales process starts with understanding our customer's complete simulation needs; what they have now, what the skill set is of their users, and what they want to achieve with simulation. We then work cooperatively with the customer to design a long-term plan to bring the right ANSYS tools to the right users and to train as needed. Once a company adds the ANSYS tools, they then have PADT to call directly for technical support. Our technical support is unique in the industry because it goes beyond the installation and error tracking that most software companies provide. When you call PADT for technical support you get an Engineer with real-world experience using the same tools you use every day. They also know engineering and how simulation fits into the process so we can go beyond what options to use and dig deep into how to apply the products properly. Our outstanding technical support is reflected in our extremely high customer satisfaction rating. You can learn more about ANSYS by visiting that part of our website, or better, by contacting us and learning why customers who have a choice on who they buy their ANSYS from, chose PADT.
Posted on December 4, 2017, by: Eric Miller"It is done running already? What machine did you run that on? Your desktop? How do I buy one?" That serious of questions from an ANSYS customer of PADT's is how CUBE Computers became one of our product offerings. We offer a complete line of six standard systems to meet the needs of the most demanding, and cost-conscious, users. The problem is that in the world of advanced numerical simulation, most off-the-shelf computers just don't perform like they should. They are expensive and are weighed down with unnecessary accessories and slowed down by poor configuration. Because PADT has been building our own computers for over twenty years for the sole purpose of running simulation models, we know how to configure boxes that are optimized for that sweet spot everyone is looking for. Our engineers and IT staff work with customers to find the right standard system, or to customize a unique system that is ideal. We break our standard models into three families: Workstations, Servers, and Cluster Appliances. Although each type can be heavily customized, we have pre-configured the following systems to make it easy for users to quickly get what they need:
Posted on October 31, 2017, by: Eric MillerIf there is one service that most people connect PADT with it is our 3D Printing Services. We have been making prototypes for companies using this ever-advancing technology since we started the company in 1994. As 3D Printing has become more popular and entered the mainstream even beyond engineering, what 3D Printing means to people has changed as well. Along with that, people's understanding of exactly what it is we do in this area has drifted a little from what goes on. In this month's installment of our "Getting to Know PADT" series, we will work to provide insight into what 3D Printing Services are and how they can benefit your company.
What is "3D Printing" and "3D Printing Services?"To start, it should be called "Additive and Advanced Manufacturing and Prototyping Services, " but people search for "3D Printing" so that is what we call it. 3D Printing is the common name for what is technically referred to as Additive Manufacturing, or AM. Most physical parts are made (manufactured) by casting or shaping material into a shape you want, removing material from stock to get the shapes you want, and/or combining physical parts you get by the other two methods. Instead of these well-proven methods, AM creates a part by building up material one layer at a time. That is why it is called additive - it adds layers of material to get a shape. Here is an older blog article showing the most common technologies used in AM. The advantage of this approach is that you just need one machine to make a part, you can go straight from a computer model to that part, and you are not held back by the physical constraints of traditional processes. These features allow anyone to make a part and to make shapes we just could not create before. At first, we only used it for prototypes before parts were made. Then we started to make tools to make final products, and now 3D Printing is employed to manufacturing end-use parts. In the world of mechanical engineering, where 3D Printing is heavily used, we call companies that use additive manufacturing to make parts for others 3D Printing Service Bureaus or 3D Printing Service Providers. Therefore, the full process of doing manufacturing using the technology is called: 3D Printing Services. The critical word in that last sentence is "full." Sending a computer model to a 3D Printer is just one of many steps involved in Additive Manufacturing. When the service is employed correctly, it includes identifying the right type of additive manufacturing to use, preparing the geometry, setting parameters on the machine, printing the parts, removing supports, cleaning the parts, sanding, applying a surface finish treatment, and then inspection and shipping. Anyone can send a part to a printer; the other steps are what make the difference between simply printing a part, and producing a great part.
What Services does PADT Offer?Additive Manufacturing covers a wide range of technologies that create parts one layer at a time, using a variety of approaches. Some extrude, some harden, some use an inkjet print head, and still others melt material. What they have in common is creating solid geometry one layer at a time. Each technology has its own unique set of advantages, and that is why PADT offers so many different 3D Printing technologies for our customers. Each of these approaches has unique part preparations, machine parameters, and post-printing processes. Each with a unique set of advantages. The key to success is knowing which technology is best for each part and then executing it correctly.
Reliability of systems
Broad material choice
Water soluble supports
Multiple materials in a single build
Broad material choices
Custom material choices
Multiple colors in single build
Water soluble supports
Fully dense metal parts
How is 3D Printing with PADT Better?The difference is in what we know and how to execute the complete process. As a provider of 3D Printing services for over 23 years, very few people in the industry even come close to the amount of experience that we bring to the table. We also know product development and traditional manufacturing, so when a customer comes to us with a need, we understand what they are asking to do and why. That helps us make the right recommendation on process, material, and post-processing. A few differentiators are:
- We know our machines
- We know our materials
- We offer a wide range of plastic and metal materials
- We understand post-processing
- We understand support removal (we manufacture the leading support removal system)
- We understand design and manufacturing
- In-house machining, painting, and part finishing
- In-house inspection and quality

Posted on September 25, 2017, by: Eric MillerUpdated on 4/6/2018: Added a paragraph on our efforts in Austin, Texas and modified California to reflect our growth there. Based in the ASU Research Park in Tempe Arizona, PADT has thrived and grown in the technologically oriented East Valley of the Phoenix Metro area. When people think about the company, they think about Phoenix and Arizona. Phoenix is even in the company name. What many people do not realize is that PADT has thriving sales and support offices in four other states. If we updated our name, it would be Southwest Simulation, Design, and Additive Technologies. However, SWSDAT is even worse than PADT! Worse yet, people might think we are from Switzerland. As the company has grown so has our sales and support territory for the products we sell. And the best way to provide outstanding support to their high-technology customers is to be part of the local technology community. So starting with Colorado in 2010, the company has been investing in the communities that are allowing it to grow. Below is a brief overview of each office and what makes them unique.
PADT ColoradoArizona and Colorado are like siblings, so alike in some ways, totally different in others. The Rocky Mountain state was the first state that saw significant growth for PADT outside of Arizona, so it was an obvious place to start growing. The bulk of our business there is around selling and supporting Stratasys Additive Manufacturing equipment. And to be blunt, it has been a great location for our engineering staff who literally could not take the heat of Arizona. Located in Littleton just south of Denver, we are close to our large Aerospace customers, and a quick drive to Boulder, Fort Collins, Colorado Springs, and Golden where we also have clusters of customers. The high-tech nature of the industry in the state fit perfectly with PADT’s strengths. From launch vehicles to mining, to cell phone cases, we have fit right in with our growing customer base. And part of our fitting there is the fantastic location on Littleton Blvd right next to the Arapahoe County courthouse. We rent a suite on the second floor a cool mid-century building that is walking distance from light rail and restaurants – a great location. If you ever visit, ask to see the bathroom and kitchen, both are a blast from the past.
PADT New MexicoOur largest customer outside of the Phoenix area is the combined Sandia National Lab, and Los Alamos National Lab, and Kirtland’s Air Force Research Lab. All are located in New Mexico and are a major focus for us for Additive Manufacturing and ANSYS sales and support. That is why our New Mexico office is so important. It is located in the Sandia Research Park, right outside the Eubank entrance to Sandia National Lab. The office provides a nice space for training as well as a location to hold office hours and meet with users who may be in locations we are not authorized to visit. Many of our non-lab customers are in that same park or nearby. This office has been a great base of operations for our continued growth in the state. This office may have the best views of any in the PADT family. Many of us also feel it also offers the best Mexican food options.
PADT UtahUtah has a small but very active technology community, and PADT’s presence in the state is growing quickly. Our office in Murray at the I-15 and 5300S is only 9 miles due south of downtown Salt Lake City. If you have not visited, the space is actually one of our more enjoyable offices to work in. One large room houses the sales and engineering team as well as a host of 3D Printers, supplies for maintenance, and a cool sitting area. Working with so many customers in Utah leads to a lot of driving, tech companies seem to be evenly distributed along the I-15 corridor, so the local team does a lot of driving. However, the office is a great central location for meeting with customers and seminars and as a starting point for those drives to Provo, Park City, and Ogden as well as destinations in-between. As our business in Utah continues to grow, we may soon have to expand this office.
PADT TexasWhen people look at PADT and where we are located, they almost always say “You should open an office in Austin, the tech community there is a perfect fit for your skills and culture.” We finally listened and are proud to announce that our newest location is in Austin Texas. This new office will be initially focused on ANSYS Sales and Support across the great state of Texas. We have had customers for other products and services in the state for decades and are pleased to have a permanent local presence now. We have hit the ground running.and have a growing group of customers who are now enjoying PADT's famous support. We hope to add engineers and more salespeople as we increase our efforts in Texas. Right now we are trying to get them to understand that Arizona Cowboys are real cowboys.
Serving our Customers BetterSometimes technology allows people to connect fairly well. However, nothing beats being local. The best way for PADT to support our customers is to not just be there for them technically, but also to be part of the communities they reside in. And that community spreads across the Southwestern United States, and we are proud to be members of the Colorado, New Mexico, Utah, and Southern California technical communities. People innovate everywhere, so we are there, local, to make innovation work for them.
Posted on August 22, 2017, by: Eric MillerThe A in PADT actually stands for Analysis. Back in 1994 when the company was started, computer modeling for mechanical engineering was called Analysis. It was such an important part of what we wanted to achieve that we put it in the name. Unfortunately, Analysis was a bit to generic so the industry switched to Numerical Simulation, or simply simulation. In the 23 years since we started, analysis... sorry, simulation, has been not just a foundation for what PADT does for our customers, it has become a defacto tool in product development. Through it all there has been a dedicated group here that is focused on providing the best simulation as a service to customers around the world.
Driving Designs with SimulationMany companies know about PADT with regards to simulation because we are an ANSYS Elite Channel Partner - selling and supporting the entire suite of ANSYS simulation tools in the Southwestern US. The success of simulation in the design and development of physical products is a direct result of the fact that these fantastic tools from ANSYS can be used to drive the design of products. This can be done in-house by companies designing the products, or outsourced to experts. And that is where PADT has come in for hundreds of customers around the world. The expertise we use to support and train on ANSYS products derives directly from our real world experience providing CFD, structural, thermal, electromagnetic, and multiphysics simulations to help those customers drive their product development. For those not familiar with simulation, or who only use the basic tools embedded in CAD software as a quick check, understanding why it is so important hinges on understand what it really is. Numerical Simulation is a methodology where a physical product is converted into a computer model that represents its physical behavior. This behavior can be many different physics: stresses, vibration, fluid flow, temperature flow, high frequency electromagnetic radiation, sloshing of liquids, deformation during impact, piezoelectric response, heating from static electromagnetic waves, cooling from air flow. The list goes on and on. Pretty much anything you studied in physics can be modeled using a numerical simulation. The process of doing the simulation consists of taking the physical object and breaking it into discrete chunks, often very small relative to the size of the object, so that equations can easily be written for each chunk that describes the physical behavior of that chunk relative to the chunks around it. Imagine writing equations for the fluid flow in a complicated valve housing, very hard to do. But if you break it up into about one million small polyhedrons, you can write an equation for flow in and out of each polyhedron. These equations are then assembled into a giant matrix and solved using linear algebra. That is why we need such large computers. We mostly use the world's leading software for this, from ANSYS, Inc.
More than Building and Running ModelsKnowing how to build and run finite element and CFD models is key to providing simulation as a service. PADT's team averages over 18 years of experience and few people come close to their knowledge on geometry preparation, meshing, setting up loads and boundary conditions, leveraging the advantages of each solver, and post processing. That is a good starting point. But what really sets PADT apart is the understanding of how the simulation fits into product development, and how the information gathered from simulation can and should be used. Instead of providing a number or a plot, PADT's experienced engineers deliver insight into the behavior of the products being simulated. How each project is conducted is also something that customers keep coming back for. Nothing is ever "thrown over the wall" our passed through a "black box." From quote through delivery of final report, PADT's engineers work closely with the customer's engineers to understand requirements, get to the heart of what the customer is looking for, and deliver useful and actionable information. And if you have your own in-house simulation team, we will work closely with them to help them understand what we did so they can add it to their capabilities. In fact, one of the most popular simulation services offered by PADT is automation of the simulation process with software tools written on top of ANSYS products. This is a fantastic way to leverage PADT's experience and knowledge to make your engineers more efficient and capable.
Unparalleled Breadth and DepthBased on feedback from our customers, the other area where PADT really stands out is in the incredible breadth and depth of capability offered. Whereas most service providers specialize in one type of simulation or a single industry, more than twenty years of delivering high-end simulation to evaluate hundreds of products has given PADT's team a unique and special level of understanding and expertise. From fluid flow in aerospace cooling systems to electromagnetics for an antenna in a smart toy, a strong theoretical understanding is combined with knowledge about the software tools to apply the right approach to each unique problem. No where is this breadth and depth exemplified than with PADT's relationship with ANSYS, Inc. Since the company was founded, PADT engineers have worked closely with ANSYS development and product management to understand these powerful tools better and to offer their advice on how to make them better. And each time ANSYS, Inc. develops or acquires a new capability, that same team steps up and digs deep into the functionality that has been added. And when necessary, adding new engineers to the team to offer our customers the same expert access to these new tools. The best way to understand why hundreds of companies, many of them large corporations that are leaders in their industry, come to PADT from around the world for their simulation services needs is to talk to us about your simulation services needs. Regardless of the industry or the physics, our team is ready to help you drive your product development with simulation. Contact us now to start the discussion.
Posted on July 26, 2017, by: Eric MillerPADT is in the business of helping people who make products. So most people think of us as a provider of tools and services. What they do not know is that PADT actually has a few of its own products. The most successful of these is our line of Support Cleaning Apparatus systems, abbreviated as SCA. These devices are used to remove soluble support material from parts 3D printed in Stratasys Fused Deposition Modeling Systems. They are robust machines manufactured and serviced by PADT, but sold through the Stratasys worldwide sales channel. As of July of 2017, over 10,800 units have been delivered to Stratasys.
Optimized Performance for Hands-Off Part CleaningThe Stratasys 3D Printing systems that use Fused Deposition Modeling extrude plastic through a heated nozzle to build parts one layer at a time. There are actually two nozzles. One puts down the building material and the other a support material that is dissolved in warm water that is slightly base. The best way to remove that support material is to put it into a warm bath where the part is gently tumbled so that the water can works its way evenly into the part. Stratasys tried several solutions for a companion washing system and eventually came to PADT and asked if we would try our hand at building a robust and efficient system. The result was the SCA-1200. Launched at the end of 2008 it met the design requirements for reliability, part cleaning time, and noise. Over 7,000 of these systems were shipped and saw heavy usage. In fact, if you have a Stratasys FDM system there is a good chance you have an SCA-1200. It contained a unique shower head design that was optimized with simulation, and a modular assembly that could be repaired easily in the field. Based upon the success and lessons learned from the SCA-1200, we released the SCA-1200HT in 2014. With the same basic form factor, this design replaced the off-the-shelf magnetically coupled pump with a simpler and more reliable custom design from PADT. The new unit also had a more pleasing visual design, several usability enhancements, and a greater temperature range. It has sold over 3,000 units and continues to be a popular system. The latest release includes a no-temperature setting that allows it to be used to clean Stratasys Polyjet parts. The success of both system lead to a request to look at building a larger machine that could clean more parts at one time as well as larger parts. The SCA 3600 has three times the volume but shares many internal parts with the SCA-1200HT. Both of the new systems are doing well in the field with even better reliability and faster part cleaning times. They are also simpler to debug and repair. The SCA systems are sold as stand alone devices or are bundled with key Stratasys FDM machines. You can learn more about them on our SCA page: www.padtinc.com/sca or you can contact whoever you buy your Stratasys equipment from. Here is a video for the SCA-1200HT that talks all about what it does: https://youtu.be/5bJPiJGHbZo
Practicing what We PreachOne of the most rewarding aspects of designing and manufacturing the SCA family of products was that it forced us to practice what we preach. We talk to companies every day about using simulation, 3D Printing, design for manufacturing, proper product development processes, and many more things needed to get a product right. With the SCA we were the customer. We had to Walk the Walk or stop talking the talk. It has been a phenomenal experience that has made us even better at helping our customers produce their new products. We used CFD to optimize the gentle agitation design and shower head and worked closely with our vendors to minimize the cost of manufacturing. The worst part was that when the schedule slipped, we couldn't blame the customer (only slightly joking). One of the best set of lessons came from doing the repair and refurbishment of systems that failed. Even though the failure rate was low, we learned a lot and were able to make improvements to future designs. Now when we sit across from a customer and talk about the design, test, and manufacture of their product, we can really say that we understand where they are coming from.
Posted on June 26, 2017, by: Eric MillerThe PADT sales and support team focused on simulation solutions is best known for our work with the full ANSYS product suite. What a lot of people don't know is that we also represent a fantastic simulation tool called Flownex. Flownex is a system level 1-D program that is designed from the ground up to model thermal-fluid systems.
What does Flownex Do?Flownex Simulation Environment is an interactive software program that allows users to model systems to understand how fluids (gas and/or liquid) flow and how heat is transferred in that same system due to that flow. the way it works is you create a network of components that are connected together as a system. The heat and fluid transfer within and between each node is calculated over time, giving a very accurate, and fast, representation of the system's behavior. As a system simulation tool, it is fast, it is easy to build and change, and it runs in real time or even faster. This allows users to drive the design of their entire system through simulation. Need to know what size pump you need, use Flownex. Want to know if you heat exchanger is exchanging enough heat for every situation, use Flownex. Tasked with making sure your nuclear reactor will stay cool in all operating conditions, use Flownex. Making sure you have optimized the performance of your combustion nozzles, use Flownex. Time to design your turbine engine cooling network, use Flownex. Required to verify that your mine ventilation and fire suppression system will work, use Flownex. The applications go on and on.
Why is Flownex so Much Better than other System Thermal-Fluid Modeling Solutions?There are a lot of solutions for modeling thermal-fluid systems. We have found that the vast majority of companies use simple spreadsheets or home-grown tools. There are also a lot of commercial solutions out there. Flownex stands out for five key reasons:
- Breadth and depth of capability Flownex boasts components, the objects you link together in your network, that spread across physics and applications. Whereas most tools will focus on one industry, Flownex is a general purpose tool that supports far more situations. For depth they have taken the time over the years to not just have simple models. Each component has sophisticated equations that govern its behavior and user defined parameters that allow for very accurate modeling.
- Developed by hard core users Flownex started life as an internal code to support consulting engineers. Experienced engineering software programmers worked with those consultants day-in and day-out to develop the tools that were needed to solve real world problems. This is the reason why when users ask "What I really need to do to solve my problem is such-and-such, can Flownex do that?" we can usually answer "Yes, and here are the options to make it even more accurate."
- Customization and Integration As powerful and in-depth as Flownex is, there is no way to capture every situation for every user. Nor does the program do everything. That is why it is so open and so easy to customize and integrate. As an example, may customers have very specific thermal-pressure-velocity models that they use for their specific components. Models that they developed after years if not decades of testing. Not a problem, that behavior can be easily added to Flownex. If a customer even has their own software or a 3rd party tool they need to use, it is pretty easy to integrate it right into your Flownex system model.Very common tools are already integrated. The most common connection is Matlab/Simulink. At PADT we often connect Excel models from customers into our Systems for consulting. It is also integrated into ANSYS Mechanical.
- Nuclear Quality Standards Flownex came in to its own as a tool used to model the fluid system in and around Nuclear Reactors. So it had to meet very rigorous quality standards, if not the most stringent they are pretty close. This forced to tool to be very robust, accurate, and well documented. And the rest of us can take advantage of that intense quality requirement to meet and exceed the needs of pretty much every industry. We can tell you after using it for our own consulting projects and after talking to other users, this code is solid.
- Ease of Use Some people will read the advantages above and think that this is fantastic, but that much capability and flexibility must make it difficult to use. Nothing could be further from the truth. Maybe its because the most demanding users are down the hallway and can come and harangue the developers. Or it could be that their initial development goal of keeping ease of use without giving up on functionality was actually followed. Regardless of why, this simulation tool is amazingly simple and intuitive. From building the model to reviewing results to customization, everything is easy to learn, remember, and user. To be honest, it is actually fun to use. Not something a lot of simulation engineers say.
Why does buying and getting support from PADT for Flownex make a Difference?The answer to this question is fairly simple: PADT' simulation team is made up of very experienced users who have to apply this technology to our own internal projects as well as to consulting jobs. We know this tool and we also work closely with the developers at Flownex. As with our ANSYS products, we don't just work on knowing how to use the tool, we put time in to understand the theory behind everything as well as the practical real world industry application. When you call for support, odds are the engineer who answers is actually suing Flownex on a customer's system. We also have the infrastructure and size in place to make sure we have the resources to provide that support. Investing in a new simulation tool can generate needs for training, customization, and integration; not to mention traditional technical support. PADT partners with our customers to make sure they get the greatest value form their simulation software investment.

Posted on May 26, 2017, by: Eric MillerProduct innovation doesn't always start with a blank sheet. Many times our customers need to begin with an accurate representation of their existing products, or a piece that theirs interfaces with, or even a competitive solutions. That is why we offer scanning and reverse engineering services that take real world parts and convert them into an accurate and useful CAD model.
What is Part ScanningPart scanning is a process where we use machines to measure geometry. Before scanning someone would use rulers, calipers, and other measuring devices dating from the industrial revolution to get critical dimensions off of a part and painstakingly document what they find. That got better with Coordinate Measuring Machines (CMM) where you could accurately measure key locations on the geometry. The problem with this approach was that it only gave you data where you measured. Fine for simple parts like a flange with bolt holes. But not good when you have crazy free-form surfaces or many features. Another approach was to section the parts and project a shadow onto a piece of paper and trace it. If you needed more measurements, cost went way up. To solve this problem, people found a way to measure lots of points easily: scan the part with some sort of optical sensor and measure points on the part as you go. Early scanning systems used lasers, measuring the beam that bounced back. This worked well, especially for very large objects. But was tricky on some surfaces and produced a lot of noise in the data. So researches figured out that they could project patterns of light and dark onto an object and measure how the edges of that pattern bent and warped. This is called Structured Light Scanning, and Wikipedia has a good article giving more details on how it works. We use the "blue light" version of this process here at PADT for our optical scanning services. The other process we use is Cross Sectional Scanning. As the name implies it scans the cross section of parts, and it does it by actually shaving off material one layer at a time and then taking a picture of the 2D cross section that is revealed. Although you consume the part in the process, it is a very accurate and fairly affordable way to measure complex internal geometry. What you get from both scanning approaches is what we call a point cloud. What is a point cloud? A file with millions of points defined as an X, Y, and Z position in space that represent locations that sit on the surfaces of the object. You can measure critical dimensions, compare different geometries, and use it as a basis to create a computer model. The key thing to note is that PADT uses precise scanners and leading software, combined with the experience of our operators to produce an accurate and usable point cloud.
How Part Scanning with PADT DifferentTo be blunt, the reason why we added scanning to our capabilities was that we had always outsourced this service for our customers. We found plenty of people with scanners, but they just scanned a part, ran the software, and provided OK data for our customers. The problem was they were not experts in the technology behind scanning, they lacked a theoretical understanding of math behind 3D computer geometry modeling, and they were not experts in product development. It turned out that scanning the geometry was the easy part, what our customers needed was someone who knew how to scan it right and produce useful information. Information they didn't have to spend time cleaning and massaging. Our engineers combine all of these skills along with a firm understanding of quality requirements, GD&T, and most of the major CAD systems. In addition, PADT is ITAR compliant and can deal with your confidential geometry and data requirements. The fact that PADT is a recognized expert in Additive Manufacturing is often useful as well. We could not find a service provider that had all of the things our customers required, so we decided to do it ourselves.
Leveraging PADT's Part Scanning and Reverse Engineering ServicesGetting parts scanned by PADT is actually fairly easy. Step one is to contact PADT and talk to our engineers so they can produce a quote. Ideally it is best for you to bring the part or parts in to our Tempe office. If that is not feasible we will need some basic pictures of your part and key dimensions like maximum length, width, and height. They will then talk with you to understand what you actually want to accomplish by scanning. Armed with this information they will provide a quote for scanning and any geometry creation or other activities you need completed including cost, schedule, and a list of deliverables. In most cases, you will ship us or drop off the part or parts, and our team will go to work. If needed, we can also come to where the parts are located and scan them there. The deliverables vary from job to job, and are negotiated as part of the quoting process. In general we will provide you with an STL or CAD file with the level of accuracy and detail that you ask for. If needed, we can also provide you with the point cloud itself. We can also complete inspection reports and provide comparisons between datasets.
