In our new modern world, much has changed. We are more connected and more mobile, working anywhere we need to. And with the emergence of the sharing economy we are letting others drive us and staying in other people’s homes. This impacts a lot of things in our lives, but one major input is that “Making a statement about who you are in a digital, shared world” is very different. Take a look at this post and think about it. How do you share who you are?
The 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 Simulation
Many 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 Models
Knowing 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 Depth
Based 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.
There is a great STEM program here in Arizona called the “Chief Science Officer” that is backed by the Arizona Commerce Authority and the Arizona Technology Council. In “Building tomorrow’s science and technology leaders with Arizona’s Pioneering Chief Science Officer program” I go over some highlights on how they take kids interested in Science, Technology, Engineering, and Math and help them become leaders in their schools and advocates for better STEM education.
Not a lot of people have the same advantage that I do, I have a profession that I really like. Being an engineer is fascinating and a true pleasure because engineering is hard, and when smart people do it right it is so interesting and exciting. It is about the process and figuring stuff out – like a solving good puzzle, but better. Learn more about why I like what I do in “Taking time to be thankful for being able to do this engineering thing“
I don’t like clickbait. It undermines the trust between information provider and consumer, and I think it needs to stop. Take a look at “You will be shocked when you read what this technology expert has to say” where I go on a bit more and channel my inner Andy Rooney. Id does also include some recommendations on how we as content users can make a difference.
We have all been there. You get back from vacation and you have eight hundred unread emails. For a lot of us we never actually make our way through them all. In “4 simple suggestions to deal with all those unread emails” I cover some ways to get through that pile and get back to being productive. If you like it… don’t email me.
Nothing makes us happier here at PADT than seeing a customer be successful with technology we worked with them on. When Jack King of DustRam came to us for a prototype for a part on his dust free tile removal product it was just the start of a fantastic journey that showed off the power of 3D Printing. After a few iterations Jack was able to replace his expensive and long lead metal mouthpiece with a plastic one that he could manufacture on demand in his own shop using his Stratasys 3D Printer.
It was such a great story that two publications were interested and wrote far better writeups than I could.
The first is interesting because it is an industry trade magazine for people in the floor installation business. Their perspective is refreshing for those of us who live in the engineering world, getting more into the practical application of the product:
This was preceded by a fantastic article in Additive Manufacturing magazine that gets more into the technical side:

PADT recently hosted the Aerospace & Defence Form, Arizona Chapter for a talk and a tour. The talk was on “Additive Manufacturing & Simulation Driven Design, A Competitive Edge in Aerospace” and it was very well received. So well in fact, that we decided it would be good to go ahead and record it and share it. So here it is:
Aerospace engineering has changed in the past decades and the tools and process that are used need to change as well. In this presentation we talk about how Simulation and 3D Printing can be used across the product development process to gain a competitive advantage. In this webinar PADT shares our experience in apply both critical technologies to aerospace. We talk about what has changed in the industry and why Simulation and Additive Manufacturing are so important to meeting the new challenges. We then go through five trends in each industry and keys to being successful with each trend.
If you are looking to implement 3D Printing (Additive Manufacturing) or any type of simulation for Aerospace, please contact us (firstname.lastname@example.org) so we can work to understand your needs and help you find the right solutions.
It is an earned privilege for older generations to make fun of younger ones. And my generation loves to bemoan those damn “Millennials!” with their phones, their laziness, and their sense of entitlement. But in reality they are just different and good business people know how to make different work for them. I explore how to take advantage of that in “Millennials in tech: Turning what makes them different into an advantage” This is our third guest blog post for the Silicon Desert insider portion of the AZ Business Magazine.
I am sick and tired of cyber security fear mongers hijacking so many technical discussion. Even meetings on STEM education seem to always devolve into a discussion on CyberSecurity. The last time this happened to me it reminded me of what it was like back in 1998 and 1999 when IT Consultants were spreading fear in order to charge huge fees to solve problems with the Y2K that many programs had. So I asked the question “Is ‘cybersecurity’ the Y2K of this generation?” and if the hysteria being spread is actually bad for solving these real and serious problems.
As we’ve seen, the threat of cyberattacks is not some abstract problem; it’s a real threat to our nation and our businesses and that’s why the use of a good security system is essential for people to keep their systems safe and running, cctv installers Melbourne provide high quality products for your business. With each passing day, we learn more about the sophistication and intent of the attackers. For example, we’ve seen a number of malicious spam campaigns using “spearphishing” tactics in recent months, using forged emails and phishing campaigns to trick their targets into disclosing information, or clicking on malicious attachments.
PADT 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 Cleaning
The 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:
Practicing what We Preach
One 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.
PADT is pleased to announce that it has partnered with Desktop Metal to resell its office-friendly and affordable metal 3D Printing solution. The partnership will also allow PADT to integrate this exciting new technology into its 3D Printer maintenance and part printing services. Desktop Metal’s new system is unique to the industry because it is a complete solution with a patented anti-sintering material that enables easily removed supports and the creation of complete assemblies. With the proprietary sintering furnace the DM Studio System delivers accurate parts quickly. PADT will be representing this new solution in Arizona, Colorado, New Mexico, and Utah.
“We are very excited to fill this gap in our product offering,” said Rey Chu, co-owner and director of manufacturing technology at PADT. “It enables us to serve customers who need stronger properties than plastic additive manufacturing systems can offer, but who don’t need a direct laser melting solution. We researched our options and watched the development of many different products. We knew Desktop Metal had the right solution when we learned that it had developed a complete package that is easy to use.”
The DM Studio System™ is based on the Metal Injection Molding (MIM) process and will start shipping this September. It is the first office-friendly platform for metal 3D printing and is considerably less expensive than existing technology. The Studio System will be sold as a package for $120,000. This includes the metal 3D printer, debinder, and microwave-enhanced sintering furnace.
As a leader in additive manufacturing for more than 20 years, PADT is a resource for customers who need 3D Printing as a service, or who need their own systems in-house. The DM Studio System™ will compliment the complete line of Stratasys FDM and Polyjet systems that the PADT resells as well as direct laser melting systems from our partner Concept Laser. Our company’s expertise with fused deposition modeling, sintering, and MIM also make us uniquely qualified to represent this solution.
“Our team is looking forward to getting this technology in front of customers,” said PADT’s Manager of Hardware Sales, Mario Vargas. “Metal 3D Printing is something our customers have wanted to add, but they could not find a turn-key solution for prototyping with various metal materials. Desktop Metal leveraged its expertise in metallurgy and software to deliver a complete system that can be run in an office environment. This is very compelling for many of our customers across industries.”
In the coming months, PADT will be setting up seminars and contacting customers across the Southwest to help educate the user community on the unique value proposition of the DM Studio System™. Anyone interested in learning more can reach out to email@example.com or call 480.813.4884, technical experts are available to explain and answer any questions.

I’m an engineer. If pushed I will tell you that function should dominate design and that spending time and resources on aesthetics or styling is a waste of money. But a little voice in my head would be screaming “No! Wrong!” because there is value in the visual beauty of something. Nowhere is that truer than in architecture
Everyone has adjusted to the fact that these days products are manufactured and sold globally. What many companies have not accepted, is that fact that the product development process is also global. If you don’t accept that and adjust, your competition will. “Developing a product in a global market” goes over the basics to successfully leveraging global resources to develop new products.
