Mars, Hearts, Spaceships, and Universities: 2019 Colorado Additive Manufacturing Day a Success

Posted on September 30, 2019, by: Eric Miller

Engineers, educators, and enthusiasts gathered on the green lawn of beside the Platte River at the Blind Faith Brewing to talk about Additive Manufacturing. Over 170 attendees (and two dogs) met each other, caught up with old colleagues, and shared their AM journey during the breaks and listened to 13 presenters and panelists. 12 antipasto platters and 30 pizzas were consumed, and 298 beers or sodas were imbibed. By the numbers and by type of interaction we saw, a successful event all around.

This was the fourth annual gathering, hosted by PADT and sponsored by our partners at this brewery. We could not have put this event on without the support of Stratasys, ANSYS, ZEISS, and Desktop Metal. We also want to thank our promotional partners, Women in 3D Printing and Space for Humanity who both brought new people to our community. Carbon, Visser and a student project with Ball Aerospace did their part as exhibitors.

Check out the Slideshow at the end of this post to get a visual snapshot of the day.

We want to thank the true stars of our event, the speakers and panelists who shared their knowledge and experience that turned a great gathering into a learning experience.

We started the morning off with an inspirational keynote from Dr. Robert Zubrin. A visionary in the space community and long term champion of going to Mars, Dr. Zubrin shared with us his observations about the new space race with his talk: "The Case for Space: How the Revolution in Spaceflight Opens Up a Future of Limitless Possibilities." He left the packed audience energized and ready to do our part in this next step in humanities exploration of the universe. He stayed after to talk with people and sign copies of his book, which you can find here.

We then heard from user David Waller of Ball Aerospace on his experience with their Desktop Metal system. He went over the testing, lessons learned, and usage of their Studio system. It was a great in-depth look at someone implementing a new technology. There is a lot of interest around this lower-cost approach to producing metal parts, and the audience was full of questions.

Sticking with the Desktop Metal technology, PADT's very own Pamela Waterman talked about how PADT is using our in-house Zeiss Optical Scanning hardware and software to inspect the parts we are making with our Desktop Metal System. She shared what we have learned about following the design guidelines that are developing for this technology and how scanning is a fast and accurate way to determine the final geometry created in the three-step process of building a green part, debinding, and sintering.

Next up was Christopher Robinson form ANSYS, Inc. to talk about recent additions to the ANSYS Additive products. He shared how customers are using simulation to design parts for metal powder bed fusion AM and then model the build process to predict and avoid failures as well as compensate for the distortion inherent in the process. The key takeaway was that simulation is the solution for getting parts built right the first time.

After a short break, and some AM trivia that won some PADT25 T-Shirts for people who knew the history of 3D Printing, we heard all about the new V650 Flex Stereolithography system that Stratasys recently introduced. Yes, Stratasys now makes and sells an SL system and it is literally a dream machine designed by people with decades of AM and Stereolithography experience. Learn more about this open and powerful system here.

Another AM technology was up next when Nick Jacobson spoke about Voxel Printing with PolyJet technologies. He discussed how he varies materials and colors spacially to create unique and realistic replicas for medicine and engineering. He also showed how the voxel-based geometry he creates can be used to create Virtual Reality representations of objects. Much of their work revolves around the visualization of hearts for adults and children to improve surgery planning. While we had been focused on space at the start of the afternoon, he reminded us of the immediate and life saving medical applications of AM.

And then we moved back to space with a presentation from Lockheed Martin's Brian Kaplun on how they are using AM to create parts that will fly on the Orion Spacecraft. Making production parts with 3D Printing has been a long-term goal for the whole industry, and Lockheed Martin has done the long and hard work of design, test, and putting processes in place to make this dream a reality. One of the biggest takeaways of his talk was how once the Astronauts saw a few AM parts in the capsule, they started asking of its use to redesign other tools and components. The ultimate end-users, they saw the value of lightweight and strong parts that could be made without the limitations of traditional manufacturing.

We finished up the day, after another break and some more trivia, with a fascinating panel on AM at Colorado's leading Universities. We were lucky to have Ray Huff from Wohlers Associates moderate a distinguished group of deans, directors, and professors from four outstanding but different institutions:

  • Martin Dunn PhD,  Dean of Engineering, CU Denver
  • Jenifer Blacklock PHD, Mechanical Engineering Professor - Colorado School of Mines
  • David Prawel PhD, Director, Idea-2-Product 3D Printing Lab, Colorado State University 
  • Matt Gordon, PhD,  Chair, Mechanical Engineering, University of Denver 

Their wide-ranging discussion covered their education and research around AM. A common theme was industry cooperation. Each school shared how they use AM to help students not just make things, but also understand how parts are made. The discussion was fantastic and ended far too soon, which is always an indicator of a great group of experts.

And that sums up our great day, leaving out several hundred side conversations that went on. Check out this slide show to get a feel for how energetic and interesting the afternoon was.

As everyone left, some reluctantly and after one more beer, the common comment was that they can't wait to get together again with everyone. We hope that next year we will have more speakers and participants and continue to support the growth of Additive Manufacturing in Colorado.

A quick note about the location: You are not wrong if you remember a different name for the three previous events. St. Patricks's is now Blind Faith and the new owners could have not been more welcoming. Plus, they have more Belgian's, which I am a big fan of.

3D Printing with Stratasys to Improve Workflow Efficiency

Posted on August 27, 2019, by: Trevor Rubinoff

As advancements in R&D continue to expand hardware innovation in almost every industry, 3D printing is playing an increasingly larger role. For a long time, companies developed prototypes via fabrication in a machine shop or outsourced to a third party contractor. This process proved to be costly and slow. With innovations like the Stratasys F123 series, industrial-grade 3D printers, prototyping is becoming simpler, more cost-efficient, and faster. PADT is a reseller and support provider for the F123 series and has seen it used to great success in its customer’s hands.

Press Release: PADT Awarded U.S. Army Phase I SBIR Grant for Combustor Geometry Research Using 3D Printing, Simulation, and Product Development

Posted on August 15, 2019, by: Eric Miller

We are pleased to announce that the US Army has awarded PADT a Phase I SBIR Grant to explore novel geometries for combustor cooling holes. This is our 15th SBIR/STTR win.

We are excited about this win because it is a project that combines Additive Manufacturing, CFD and Thermal Simulation, and Design in one project. And to make it even better, the work is being done in conjunction with our largest customer, Honeywell Aerospace.

We look forward to getting started on this first phase where we will explore options and then applying for a larger Phase II grant to conduct more thorough simulation then build and test the options we uncover in this phase.

Read more below. The official press release is here for HTML and here for PDF.

If you have any needs to explore new solutions or new geometries using Additive Manufacturing or applying advanced simulation to drive new and unique designs, please contact us at 480.813.4884 or info@padtinc.com.


PADT Awarded U.S. Army Phase I SBIR Grant for Combustor Geometry Research Using 3D Printing, Simulation, and Product Development

The Project Involves the Development of Sand-Plugging Resistant Metallic Combustor Liners

TEMPE, Ariz., August 15, 2019 ─ In recognition of its continued excellence and expertise in 3D printing, simulation, and product development, PADT announced today it has been awarded a $107,750 U.S. Army Phase I Small Business Innovation Research (SBIR) grant. With the support of Honeywell Aerospace, PADT’s research will focus on the development of gas turbine engine combustor liners that are resistant to being clogged with sand.  The purpose of this research is to reduce downtime and improve the readiness of the U.S. Army’s critical helicopters operating in remote locations where dirt and sand can enter their engines.  

“PADT has supported advanced research in a wide variety of fields which have centered around various applications of our services,” said Eric Miller, co-founder and principal, PADT. “We’re especially proud of this award because it requires the use of our three main areas of expertise, 3D printing, simulation and product development. Our team is uniquely capable of combining these three disciplines to develop a novel solution to a problem that impacts the readiness of our armed forces.”

The challenge PADT will be solving is when helicopters are exposed to environments with high concentrations of dust, they can accumulate micro-particles in the engine that clog the metal liner of the engine’s combustor. Combustors are where fuel is burned to produce heat that powers the gas turbine engine. To cool the combustor, thousands of small holes are drilled in the wall, or liner, and cooling air is forced through them. If these holes become blocked, the combustor overheats and can be damaged.  Blockage can only be remedied by taking the engine apart to replace the combustor. These repairs cause long-term downtime and significantly reduce readiness of the Army’s fleets.

PADT will design various cooling hole geometries and simulate how susceptible they are to clogging using advanced computational fluid dynamics (CFD) simulation tools. Once the most-promising designs have been identified through simulation, sample coupons will be metal 3D printed and sent to a test facility to verify their effectiveness.  Additionally, PADT will experiment with ceramic coating processes on the test coupons to determine the best way to thermally protect the 3D printed geometries.

“When we developed new shapes for holes in the past, we had no way to make them using traditional manufacturing,” said Sina Ghods, principal investigator, PADT. “The application of metal additive manufacturing gives PADT an opportunity to create shapes we could never consider to solve a complex challenge for the U.S. Army. It also gives us a chance to demonstrate the innovation and growth of the 3D printing industry and its applications for harsh, real-world environments.”

Honeywell joined PADT to support this research because it is well aligned with the company’s Gas Turbine Engine products. The outcome of this research has the potential to significantly improve the performance of the company’s engines operating in regions with high dust concentrations.

This will be PADT’s 15th SBIR/Small Business Technology Transfer (STTR) award since the company was founded in 1994. In August 2018, the company, in partnership with Arizona State University, was awarded a $127,000 STTR Phase I Grant from NASA to accelerate biomimicry research, the study of 3D printing objects that resemble strong and light structures found in nature such as honeycombs or bamboo.

Talking Hydrogen Fuel Cell Blowers for Trucking at the Governor’s House

Posted on July 11, 2019, by: Eric Miller

As we shared in our recent press release, PADT was invited to be one of nine companies presenting at the 2019 Commercial Vehicle Cleantech Challenge. We happily spent the day at the Colorado Governor's mansion talking and learning about how to make the road transportation of goods with large and small vehicles cleaner and more efficient. As one of nine companies presenting, PADT talked about our custom blower technology for hydrogen fuel cells.

We want to thank both the Colorado Cleantech Industries Association (CCIA) and the North American Council for Freight Efficiency (NACFE) for hosting such an informative event. We were able to meet people from across the energy and learn about their needs, and give them an opportunity to learn more about PADT.

You can find their blog post here.

Here are some pictures describing how our day went.

The building and grounds at the Colorado Governor's Mansion are truly beautiful. We spent most of the day in the carriage house in the garden... which I failed to get a picture of.

It was a packed day as can be seen from the agenda. And the list of sponsors was fantastic. We were able to talk with key industry visionaries for more efficient and cleaner commercial vehicle fleets.

One of my favorite things about the site were these very cool napkins they gave us. Nice seal. And, "Executive Residence" sounds so much classier than "the Gov's House"

We spent most of our day in the green room where they gave us wifi, coffee, power, and a flat surface. So Rob and I set up a portable office. The three blowers we brought with us helped decorate the place.

We can's share the full presentation, but we can discuss some key slides. They gave us 10 minutes to talk about our solution, then 10 for questions.

The problem is fairly simple. People designing stacks need custom blower solutions because of the hydrogen and the pressure/flow requirements on the air side of a hydrogen fuel cell.

PADT's proven solution is to design custom blowers to meet very specific needs.

In the end, we just wanted to know that we are excited to see that Hydrogen fuel cells are seeing a resurgence, our blowers are perfect for most applications, and that we would love connections to people who need our solution.

When we were done we went inside the house. Room after room was stunning.

We gave a 2-minute short presentation with this great view behind us.

A great day where we met a lot of great people from around the country. Sadly, PADT didn't win the competition. The truth is that the challenge was for new and disruptive technology and we talked about proven and enabling solutions. Useful to the sponsors, but not what they were looking for when handing out prizes.

Visiting Colorado in the summer is always a nice break for those of us from Phoenix. We hope to participate in this and related events in the future.

If you have any needs for air our hydrogen blowers for your fuel cell, or any complex engineering for your product, please contact us and we would love to learn how we can help.

History for the future: PADT seals time capsule as part of 25th-anniversary celebration

Posted on July 9, 2019, by: Eric Miller

The past is a tricky thing to remember. When we started preparing for PADT's 25th anniversary celebration we spent a lot of time thinking about the past, about our journey from an idea to the thriving business we are today. And one though kept coming back to us, "we really should have captured and stored more."

We can't change that past but we can preserve our history for the future with a Time Capsule. On July 1st of 2019, we took 49 items and crammed them into a sealed box that we embedded into the wall of PADT's Tempe headquarters.

You can see a list of all the items at the bottom of this post. Some of the highlights are a copy of our different business card designs over the past 25 years, a collection of PADT logo'd shirts, bits and pieces from our SCA product, parts from various fuel cell blowers, samples of 3D Printed parts, and some old manuals. We also included a collection of tech from the past 25 years including four cell phones of various types.

The most interesting object we stored from our perspective was a binder with documents and images from the past 25 years. Here are some of the items in that binder that are interesting today:

A timeline of PADT Business Cards over the past 25 years. We did think they looked cool back then.
We didn't take any early photos, but we do have pictures of most of our employee for almost every year since 2000.
Our first report to a customer was a stress analysis for a sprinkler valve housing.
Our staff took a look at the way things were in 1994 and in 2019. Technology, politics, entertainment, and news. A great look back at then and now.

It was a lot of fun gathering the items and thinking about the impact they all had on PADT over the years.

All of that stuff we wanted to save is piled on the cart. A lot of memories.

On Monday we crammed it all in and sealed it up. In 25 years, July 1, 2044, PADT employees, customers, and partners of the future will open it up to see what is inside. That is not too far into the future and with luck, many of us will be around to witness it.

PADT's founders... 25 years older... Eric Miller, Ward Rand, and Rey Chu
Jeff expertly filled the box full
Co-Founder, Rey Chu puts in the first screw.
Ward Rand adds the second fastener.
Eric Miller tightens everything up.

We wonder what they will make of our past, some of which will be fifty years old by then. Will they laugh? Or scratch their head wondering what the heck a cell phone was? We can't wait to find out.

PADT’s Penchant for Patents

Posted on June 5, 2019, by: Eric Miller

When they walk into PADT's main office in Tempe, Arizona, the first thing most people notice is our "wall-o-patents." Over the years, PADT employees have been named on 43 patents. They range from fuel cell membranes to silicon wafer coating to a slew of medical devices. When we received notification that staff members were listed as co-inventor on two patients with numbers over 10,000,000 we thought it was a good excuse to celebrate the years of contributions our engineers have made.

The rich collection highlights the diversity of industries we work on and the ingenuity of our staff. When the companies who own the Intellectual Property (IP) represented on that wall came to PADT looking for assistance with research, development, troubleshooting, and testing of their products they found a partner that did more than carry out tasks. PADT collaborated with them to create novel solutions and approaches that resulted in IP.

You can view all of our patents on our wall... or on our patent page here.

We want to say thank you to our staff and our customers for letting us be part of their innovation.

If you are looking for a partner that can work with you to turn your ideas in into Intellectual Property, please learn about our Product Development team or reach out to info@padtinc.com.

Seven Tips for 3D Printing with Nylon 12CF

Posted on April 10, 2019, by: Pam Waterman

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.

Best Practices for Successful Part Production

Follow these steps to produce best-practice Nylon 12CF parts:
  1. Part set-up in Insight or GrabCAD Print software:
    • If the part has curves that need a smooth surface, such as for use as a bending tool, orient it so the surface in question builds vertically. Also, set up the orientation to avoid excess stresses in the z-direction.
    • The Normal default build-mode selection works for most parts unless there are walls thinner than 0.2 inches/0.508 mm; for these, choose Thin Wall Mode, which reduces the build-chamber temperature, avoiding any localized overheating/melting issues. Keep the default raster and contour widths at 0.2 inches/0.508 mm.
    • For thin, flat parts (fewer than 10 layers), zoom in and count the number of layers in the toolpath. If there is an even number of layers, create a Custom Group that lets you define the raster orientation of the middle two layers to be the same – then let the rest of the layers alternate by 90 degrees as usual. This helps prevent curl in thin parts.
    • Set Seam Control to Align or Align to nearest, and avoid setting seams on edges of thin parts; this yields better surface quality.

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.
