|With:||Eric Miller, Ted Harris, & Dr. John Swanson|
In this episode your host and Co-Founder of PADT, Eric Miller is joined by PADT’s Ted Harris for a very special interview for users of ANSYS software, Dr. John Swanson. Dr. Swanson is known as the founder of “Swanson’s Analysis Systems” in 1970; the company that would later be known to the public as ANSYS Inc. He also wrote the original ANSYS program in his home, and since leaving the company has gone on the work in philanthropy and alternative energy.
A John Fritz Medal winner, and member of the National Academy of Engineering, John is considered an authority and pioneer in the application of Finite Element methods to engineering.
We are incredibly thankful that John was able to join us for this interview, and we hope you enjoy learning a little bit about the history of ANSYS from the founder himself.
If you have any questions, comments, or would like to suggest a topic for the next episode, shoot us an email at firstname.lastname@example.org we would love to hear from you!
If you’ve been thinking of trying out Nylon 12 Carbon Fiber (12CF) to replace aluminum tooling or create strong end-use parts, do it! All the parts we’ve built here at PADT have shown themselves to be extremely strong and durable and we think you should consider evaluating this material.
Nylon 12CF filament consists of black Nylon 12 filled with chopped carbon fibers; it currently runs on the Stratasys Fortus 380cf, Fortus 450 and Fortus 900 FDM systems when set up with the corresponding head/tip configuration. (The chopped fiber behavior requires a hardened extruder and the chamber runs at a higher temperature.) We’ve run it on our Fortus 450 and found with a little preparation you get excellent first-part-right results.
With Nylon 12CF, fiber alignment is in the direction of extrusion, producing ultimate tensile strength of 10,960 psi (XZ orientation) and 4,990 psi (ZX orientation), with tensile modulus of 1,100 ksi (XZ) and 330 ksi (ZX). By optimizing your pre-processing and build approach, you can create parts that take advantage of these anisotropic properties and display behavior similar to that of composite laminates.
Follow these steps to produce best-practice Nylon 12CF parts:
2. In the Support Parameters box, the default is “Use Model Material where Possible” – keep it. Building both the part and most of the surrounding supports from the same material reduces the impact of mismatched thermal coefficient of expansion between the model and support materials. It also shortens the time that the model extruder is inactive, avoiding the chance for depositing unwanted, excess model material. Be sure that “Insert Perforation Layers” is checked and set that number to 2, unless you are using Box-style supports – then select 3. This improves support removal in nearly enclosed cavities.
3. Set up part placement in Control Center or GrabCAD Print software: you want to ensure good airflow in the build chamber. Place single parts near the center of the build-plate; for a mixed-size part group, place the tallest part in the center with the shorter ones concentrically around it.
4. Be sure to include a Sacrificial Tower. This is always the first part built, layer by layer, and should be located in the right-front corner. Keep the setting of Full Height so that it continues building to the height of the tallest part. You’ll see the Tower looks very stringy! That means it is doing its job – it takes the brunt of stray strings and material that may not be at perfect temperature at the beginning of each layer’s placement.
5. Run a tip-offset calibration, or two, or three, on your printer. This is really important, particularly for the support material, to ensure the deposited “bead” is flat, not rounded or asymmetric. Proper bead-profile ensures good adhesion between model and support layers.
6. After printing, allow the part to cool down in the build chamber. When the part(s) and sheet are left in the printer for at least 30 minutes, everything cools down slowly together, minimizing the possibility of curling. We have found that for large, flat parts, putting a 0.75-inch thick aluminum plate on top of the part while it is still in the chamber, and then keeping the part and plate “sandwiched” together after taking it out of the chamber to completely cool really keeps things flat.
7. If you have trouble getting the part off the build sheet: Removing the part while it is still slightly warm makes it easier to get off; if your part built overnight and then cooled before you got to it, you can put it in a low temp oven (about 170F) for ten (10) to 20 minutes – it will be easier to separate. Also, if the part appears to have warped that will go away after the soluble supports have been removed.
Be sure to keep Nylon 12CF canisters in a sealed bag when not in use as the material, like any nylon, will absorb atmospheric moisture over time.
Many of these tips are further detailed in a “Best Practices for FDM Nylon 12CF” document from Stratasys; ask PADT for a copy of it, as well as for a sample or benchmark part. Nylon 12 CF offers a fast approach to producing durable, custom components. Discover what Nylon 12CF can mean for your product development and production groups.

It is not often that 350+ people get together in a parking lot to talk about Engineering, bouncy houses, economic development, and eat Bar-B-Que. On March 21st, all three of those things and more happened at PADT’s party to celebrate our 25th anniversary. What a fantastic crowd. What a great roster of speakers. We could not have asked for better people to come to our event.
We want to offer special thanks to those twelve speakers:
The highlight of the event were four student teams that PADT supports in one way or another. Lego robots, 3D Printed prosthetic hands, FIRST Robots, and a formula SAE car were on display and were very popular. Every time we have these teams come and show their stuff, we are reminded that the future does have hope. We also hope that at the 30th, 35th, and 40th anniversary celebrations some of those students will be wearing PADT shirts.
For fun there were two bouncy houses, face painting, temporary tattoos, and two cornhole sets. And as always, PADT’s 3D Printing demo room was open for everyone to see the cool things our customers and we are printing every day.
The best part of the whole day was simply thanking our employees and customers for 25 Fantastic years. Please enjoy some images from the event below.
As always, if you have any questions or want to know more about PADT, simply contact us.
It has been an incredible journey with so many people playing key roles.

One of the most exciting, and terrifying, aspects of being a parent is when it is time for your children to head out on their own. Here at PADT we have been growing and nurturing our 3D Printing Post Processing business for 10 years. With 12,500 Support Cleaning Apparatus systems in the field globally, it was time to give our SCA business the freedom it needs to grow.
Initially, not much will change, other than the name as we focus on building an outstanding team that is as excited as we are about this much-needed aspect of 3D Printing. Stay tuned as we all watch Oryx Additive grow and prosper.

In the factory of the future automation is king.
Manufacturers can drastically reduce lead times, reduce labor costs, and increase overall efficiency through the use of robotics at several stages in their workflow, each performing a different function. While each function serves a unique purpose specific to the task it will execute, they all utilize an essential component known as End-of-Arm tooling (EOAT).
Traditionally, companies that produce EOAT have used extruded aluminum, or machined aluminum frames, often making them heavy and cumbersome. One manufacturer however, has found a solution to reduce weight without sacrificing strength or durability, using 3D printing.
Download the case study to learn more about additive manufacturing’s place on the factory floor, and how you can use it to eliminate the need for heavy and overly complex parts.
Create parts that are 50% lighter, and designed based on your needs, not limited by your manufacturing process.

Just a few more days before PADT’s Holiday break between Christmas and New Year’s Day. As much as we try to finish things up, 2018 is not going to bed without a fight. Everyone is busy. And that is what the entire year was like.
Some years you remember more than most, and I think 2018 will be one of the more memorable years.
We had a lot of new activities and made a lot of noise in the community. If you scroll through the list of milestones below you will see that we opened offices, won research grants, received awards, and added partners. And much more. We could have never achieved so much without our outstanding employees, supportive partners, and fantastic customers.
Three of those events stand out to me and are worth mentioning here in this final blog entry of the year.
The first happened at the start of the year when we launched ANSYS sales in Austin, Texas. We have been selling and supporting customers in Arizona, Colorado, Utah, and New Mexico for decades. We have also been doing business in California for some time. The addition of Texas was special because it was our first major growth east of the Rocky Mountains. Texas is culturally very much a part of the Southwestern US, and it felt right to add branch out there. And it has gone great. We are reconnecting with people we knew through consulting, meeting new customers, and adding long-term ANSYS customers to our user family. It has been great. And the Bar-B-Que is as good as everyone promised.
Texas was all about moving east. The next important milestone was about moving up. Up into space. We have been in the Additive Manufacturing business since we started PADT, and many of our customers have been Aerospace companies. They have worked with us to make prototypes and tooling that helped them get better solutions into orbit faster. But never have they tried to fly structural 3D Printed parts. Until this year.
NASA, Lockheed Martin, Stratasys, and PADT worked together to put the right processes, materials, and Additive Manufacturing systems in place to allow Lockheed Martin to deliver next-generation 3D printed parts for NASA’s Orion deep-space spacecraft. They manufactured a docking hatch door using Stratasys Antero 800NA material that is approved for flight. In fact, the plan is to take the spacecraft beyond the orbit of the moon as a test. We are very proud to have played a role in making this happen.
The last achievement worth emphasizing is one of the awards we received. The ANSYS Technical Support Team from PADT was a Silver Winner of the 2018 Customer Service Department of the Year Award. A Silver Stevie. Not only is this remarkable because it is national recognition for what our team does, it comes during the busiest technical support year we have ever faced. As ANSYS adds products and customers, the team’s job gets harder. And they step up to the plate (well, phone or email client) every day and satisfy customers. The reviewers at the American Business Awards stated: “PADT defines what premium customer service looks like.” Great recognition for all of their hard work.
Some further highlights from the year are listed below.
As we rush to get things done and eat more holiday treats off the table in the hallway, we want to thank everyone who helped make this a memorable year. All of us at PADT look forward to creating even more memories and establishing greater milestones in 2019.
Additive Manufacturing has been making a transition from a prototyping tool to an accepted way to make tooling and end-use parts across industries, and specifically in the Aerospace industry. PADT has always been at the leading edge of this transformation and today we are pleased to announce the next step in this evolution: The Quality Management System PADT uses to manage our scanning and 3D printing services have been certified to be compliant to the AS9100D(2016) and ISO9001:2015 standards.
This certification will allow our Aerospace customers to come to PADT with the knowledge that an accredited quality organization, Orion Registrar, Inc., has audited our QMS and it meets the requirements of the latest aerospace manufacturing quality standards. Developing our QMS to meet these standards has been an ongoing effort in PADT’s Advanced Manufacturing Department that separates the scanning and 3D Printing services we offer from most service providers. This investment in developing a robust and effective QMS and the certification it has received reaffirms our commitment to not just print or scan parts for people. PADT takes quality, process, and customer satisfaction seriously.
Even if they are not printing or scanning Aerospace components, customers benefit from our certified QMS. Every project is conducted under an established system that builds in quality, inspects for it, and continuously improves.
This milestone would not have been achieved without the dedication of our quality team along with the cooperation and enthusiasm of our Advanced Manufacturing staff. From front-office to facilities to machine operators, everyone did their part to establish a high standard and then achieve certification.
The best way to understand the advantages of how PADT does Scanning and 3D Printing is to try us out. You can also learn more by visiting our Aerospace Manufacturing page where we talk about our QMS and the services it covers.
If you have any questions about our certification, additive manufacturing, or scanning & reverse engineering, reach out to firstname.lastname@example.org or call 480.813.4884.
This has been a busy year for PADT. So busy in fact that we forgot an important announcement from January. PADT was granted US Patent 9,878,498 for some of the technology we use in our line of devices that remove soluble supports from 3D Printing parts. The official title: METHOD AND APPARATUS FOR REMOVING SUPPORT MATERIAL is actually fairly accurate. It covers the hardware configuration inside the device along with the methods that are used for the systems we make and sell for removing support material from 3D Printed parts.
PADT introduced our first Support Cleaning Apparatus (SCA) to the market in 2008. We learned a lot from that first SCA-1200 and developed intellectual property around the equipment and methods we used in our second generation systems, the SCA-1200HT and SCA 3600. With over 12,000 total units shipped, these machines take the work out of support removal making 3D Printing faster and easier.
Take a look at the press release below, or the patent itself, to learn more about what makes our systems unique and better. Decades of experience in 3D Printing, product development, and simulation went into developing the ideas and concepts capture in the patent and realized in the reliable and easy-to-use SCA product family.
If you have any questions about our support removal solutions in particular or 3D Printing in general, reach out to email@example.com or call 480.813.4884.
For as long as PADT has been involved in Additive Manufacturing, we have been interested in how the process of building geometry one layer at a time could be used to more closely represent how nature creates objects. Nature is able to create strong, lightweight, and flexible structures that can not be created using traditional ways of manufacturing like machining, molding, or forming. 3D Printing gives engineers and researchers the ability to explore the same shapes that nature creates.
As you can imagine, strong and light structures are very beneficial for objects that need to be launched into space. That is why NASA just awarded PADT and Arizona State University, a Phase 1 STTR grant to explore how to make just this type of geometry. We are excited to work with ASU to define what the possibilities are in this first phase and then apply for a Phase 2 grant to bring real-world applications of this technology to industry.
This is PADT’s 14th SBIR/STTR and our second joint project with Dr. Dhruv Bhate at ASU. Many of you may remember the research and process improvements that Dhruv worked on when he was a PADT employee. We look forward to sharing our results with the Additive Manufacturing community and moving this exciting application for the technology forward.

We have a fantastic visit this morning from Cory McCloskey from KSAZ Fox10, one of our local TV Stations.
They gave us a chance to show off our new Carbon On-Demand Manufacturing technology, some of the printing with do with Stratasys Objet technology for medical applications, and even spoke to our interns Garrett and Austin about the work they are doing with NASA.

It is always great when we can show off any bit of what we do here at PADT.
Sometimes if you look hard enough, you find what you need. Ever since people started talking about running large simulation models in the “cloud” our engineers here at PADT have been looking for a good solution. We even offered our own service, and although it was fast and easy to use, we could not make it big enough. Then along comes Nimbix. And they nailed it.
First we asked, are they running on real HPC hardware, not souped up web servers with virtual machines on them? Yes. We found bare metal hardware striped down to fighting weight that is optimized for running simulation.
Then we asked, Is it easy to use or do I have to jump through hoops to just get a job running? Indeed it was easy and powerful. We just wanted to submit jobs and found that the JARVICE™ interface does so much more to configure, setup, submit, and monitor even the most complex parallel solves.
OK, this looked good, but the real test is do we have access to whole machines or is this just a timesharing system with a great interface? Turns out it is not. It is true cloud-based high-performance computing.
We think we found what we were looking for, but we have been burned before. So we did what any simulation engineer would do, we pounded on it with massive ANSYS FLUENT, Mechanical, and HFSS runs. We knew it was real when we were monitoring a CFD run on a mobile phone from a coffee shop in-between customer visits.
We liked it so much that we asked if we could partner with them to offer it to our customers. And that is where we are today with this press release.
PADT is proud to announce that we are able to provide our customers with on-demand HPC resources that are fast, easy to use, and cost-effective. If you are a simulation user who needs to run large jobs, access surge capacity, or just solve faster, Nimbix is the answer. And PADT is here to help determine the right configuration and guide you through the process.
Please read the press release below for more details on what we are doing.
