My Fellow Users,
It was amazing to see all of you at our users group conference. The sharing of information and debating of ‘facts’ was amazing and nonstop. And seeing everyone enjoy the event was invigorating.
I had barely enough time to see what all of our sponsors and exhibitors had to offer. Getting to learn of all of the new and innovative advancements made the effort worthwhile, and I am still processing what I discovered. As usual, having other members to confer with, and to share with, really helped. I hope you were able to gain the insights that will help you answer your questions and advance your AM projects. But the information flow doesn’t end with the conference. For example, you will also see a lot of sponsor information shared in this newsletter right up to the start of AMUG 2022. Please support the AMUG sponsors…I encourage you to reach out to them for your AM needs.
During AMUG 2021, we heard from four scholarship winners. Sitting in on their presentations, I found the discussions of their work fascinating, and I was moved/touched by their stories. The scholarships are a great tool to help build successes for our members and the industry. Getting these brilliant up-and-coming minds involved provides an avenue for them to apply their passion to our industry. In this newsletter, we hear firsthand accounts of the AMUG experience from two Guy E. Bourdeau Scholarship winners, Kate Schneidau and Sean Dobson.
I want to thank all of the candidates that accepted a nomination for our director positions. We had an impressive slate of candidates for the election. And with our members’ votes, we have a great AMUG Board that will take the reins on July 1st. Considering board transitions, open projects, and 2022 planning, we have a lot of work to do. But I am confident that we will be able to prevail. After all, look what we had to do to pull off a fantastic AMUG 2021. Please reach out with your comments and any words of support for all of our volunteers.
We have a lot of information that will be coming at you as we wind down AMUG 2021 and spin up AMUG 2022. This information will be communicated through our LinkedIn posts (and other social channels), the newsletter, and the website. Keep an eye out for all of our communications with more details and sponsor information.
I look forward to toasting with you at the next opportunity that we have to get together! Please be safe until we meet again.
All the best!
Second generation DINO
DINOs are rare (only 174 awarded in 33 years). Rarer still are ‘seconds.’ There are two individuals (Joe Allison and Graham Tromans) with two DINOs. And there are several companies that had multiple employees receive DINOs, such as BD, DSM, GE Additive, and ProtoCAM. With DINOs awarded to Jerry Bordner (2010), Bret Bordner (2011), and Paul Bordner (2013), AMUG had its first occurrences of second-generation recipients.
With the 2021 DINO presentations, we had a second occurrence. When Robin Van Bragt of Eagle Design and Technology Inc. accepted her award, her family became the second to have second-generation DINOs. Back in 2010, her father, Bruce Okkema, received his DINO.
Robin and Bruce held the same position (president of Eagle Design and Technology) when they were named as DINOs.

My AMUG 2021 Experience
While the journey to my very first AMUG Conference was not what I envisioned, I can say without a doubt that it was worth the wait. Everything I had been told to expect was reached and exceeded within the first day. Words cannot describe the feelings of attending AMUG 2021, especially for the first time, and meeting so many individuals with a boundless passion for AM.
I learned an incredible amount about applications, processing techniques, and even about other technologies I previously knew nothing about beyond news articles. With many session tracks to choose from, I was able to learn not only about advancements in my application background but introduce myself to different perspectives in additive from nanometals to casting and mold making. I attended the hands-on silicone mold making and urethane casting workshop. While I met challenges that did not allow my success, I enjoyed myself, the topic, and the conversation with the instructors and other attendees. Next year, I will go through the workshop again and walk out with a finished part.
Personally, my favorite parts of the week were the networking dinners. At the beginning of the week, I met and talked to the many people who came early to the AMUG Conference to set up. They embraced me with open arms and spoke with me—not just about additive but also about life. I felt as though I had entered a giant family. Anyone I spoke with was so excited to be there and was engaging to learn more about the other person, especially since they knew it was my first year attending. I knew before the conference started that AMUG is a group of people who truly live and work with the intent to share and build relationships with their peers. This was only confirmed through the week as I met with more attendees and had the chance to not only talk about new technologies and applications but hear their stories of projects that they have done in the past. I received a history lesson on additive and AMUG that had me excited for the future. Since I am part of the next generation, I can use that knowledge that I learned to bring about more innovation and share with more young people who want to get involved in additive.
Having an extra year before attending my first AMUG, due to the postponement of the 2020 event, only made me appreciate the conference even more. My journey has only begun in additive, but I know that as I progress through my career, AMUG Conferences will be the events I will attend every year. There is so much I do not know within the field of additive, but I am excited to continue learning.
I am forever grateful to all the people I met at AMUG 2021 and the relationships that I created. Thank you to Renee Bourdeau, Cimquest, and the AMUG Board for giving me the opportunity to share my work and meet so many individuals. And I thank them for having this annual scholarship so that other students can start their AM journey meeting people who can impact their lives within the span of a week, just like I did.
I cannot wait for next year’s AMUG Conference.

My AMUG 2021 Experience
My AMUG 2021 experience was as expected in some respects and in others completely unforeseen. I had expected to network with great people and learn some of the incredible initiatives being developed within the AM industry. I had expected to see some great talks from leaders in their fields. I had expected an abhorrent amount of great food and drink. These expectations were met, especially that last one, because this was what the AMUG Conference was ‘pitched’ to me as. However, I did not anticipate how personally meaningful the experience would be to me. The people who run this event and those who attend are family, and I felt overwhelmed, in the best way, to be a part of it.
The conference and its activities proved two things: I had already learned a lot about my industry, and I had a lot more to learn. I was surprised and appreciative of how well curated the discussions were. I was able to keep up in my somewhat limited experience while also acknowledging potential avenues to explore in my various projects. Additionally, I was shocked when talking to people by just how knowledgeable yet excited they were about what they were working on. It made networking not only necessary but enjoyable.
In my application essay for this scholarship, I mentioned in my conclusion that “AMUG is a place where the titans of our industry meet….” While this is correct, the sentiment was wrong. Yes, big players in the industry come to the AMUG Conference, but they are not cordoned off in some strange VIP area I had created in my mind. They were usually the ones coming up and introducing themselves, asking the questions, and genuinely curious about my response. It was a refreshing and meaningful point that stuck out to me about the conference.
However, the event’s setup; the time squeezed in between sessions; and the late nights were where much of my personal and professional growth occurred over the week. One of the hundreds of people I had the pleasure of meeting used the adage, “You get out what you put in with AMUG.” I couldn’t agree more. You might be tired from that 3 a.m. chat with a select few who accompanied you on laps around the lazy river (just a hypothetical), but it’s the jovial commiseration that your diet will start again at the end of the event, the inside jokes you somehow developed in the two days of knowing someone, and the realization that some of these people will become lifelong friends, that carries you to the next 3 a.m. lazy river escapade.
I wouldn’t trade my AMUG experience for anything and can’t wait to help out next year and see my friends again.

New toolpathing API for AM
On April 20, 2021, at the annual Dyndrite Developer Conference, Dyndrite CEO Harshil Goel revealed new toolsets as part of the Dyndrite Accelerated Computation Engine (ACE) Toolpathing API. Developed by working directly with our raster and vector OEM customers and the Dyndrite Developer Council (DDC) members, these toolsets open a new era in software and hardware development for AM.
- Control over RGBA and distance fields for functional grading in raster processes
- Anisotropic compensation in raster processes
- Support-free metal additive through field-based segmentation
Additionally, Dyndrite leverages GPU acceleration and Python-driven automation tools. GPU acceleration allows AM software to catch up to the performance of additive hardware. With significantly faster slicing, you can simulate and test more quickly, certify parts and materials more rapidly, produce more complex parts, increase production rates, and help additive realize its potential.

Exploring new horizons in 3D metal printing
Metal filament 3D printing offers a galaxy of benefits: Geometric design freedom without the need for molds or castings, outstanding strength and corrosion resistance even with increased form complexity, and a greatly simplified production process from prototype to serial production. Even better, the major investments in machines and tooling required by previous metal 3D printing methods are now history.
During catalytic debinding, the binding agents are removed in preparation for final sintering. This can cause a loss of stability and structural integrity in the printed component.
To reduce the risk of distortion or collapse, our Virtual Engineering Team recommends performing a virtual debinding stability analysis before printing. This provides an estimation of internal stresses to evaluate the part’s structural integrity during debinding—and also gives a visual indication of which structural features are at risk. With our Debinding Stability Simulation Guideline, you can quickly and easily determine which features may not yet be optimal for metal filament printing.

Essentium’s rapid prototyping speeds time to innovation
Rapid prototyping through 3D printing gives manufacturers the flexibility to develop, test, and refine products or part designs before committing to costly large-scale production. However, innovation speed is entirely dependent on making the prototyping process fast, efficient, and effective.
Traditional AM platforms are often hindered by lengthy revision turnaround times for prototype refinements. Multiple revisions can be created in rapid succession by utilizing a machine like the Essentium High Speed Extrusion (HSE™) 3D Printing Platform.
On June 23 at 10 a.m. CST, Essentium will host a webinar focused on how to leverage the HSE 3D Printer to make changes quickly and print them with high speed. Additional topics will include techniques on how to create multiple revisions of a part without the cost of additional time, as well as methods to segment complex geometries to speed slicing revisions on whole parts.

Case study: Metal binder jetting speeds up product development at MSA Safety, Inc.
MSA Safety, Inc. leads the industry in innovative products that protect people and facility infrastructures. MSA needed to determine a process to allow engineering to quickly iterate metal parts through design concepts while saving time, reducing cost, and shortening time to market.
MSA turned to ExOne for their metal binder jetting expertise, and since then, ExOne’s technology has helped ensure MSA products get developed quickly for testing so they can get to customers even faster.
“ExOne saved us a good amount of time. Time is critical for all projects at MSA. Lead times for a tool are 16-plus weeks, meaning we would traditionally have to order these parts without a good prototype solution to evaluate performance. ExOne’s solution allows the engineering team to quickly iterate through design concepts, saves time, and price savings over buying a tool.” Matthew Jacob, Mechanical Engineer, MSA.
