AMUG July 2021

By July 22, 2021

July 2021

President’s report

Hello AMUG Members,

July marks the start of our new board of directors. Please help me in welcoming the new directors to the AMUG Board. We are excited to have them join yet saddened to see some of the past board members step down. However, this new team is working hard to keep our organization fresh and exhilarating. We appreciate your help in doing this.

It’s a very challenging schedule, considering our shortened time frame between conferences, where we address everything from our last event and build a great AMUG 2022. Your feedback is greatly appreciated, and we will work to incorporate all the improvements that we can. Should you ever have ideas to share, we are always eager to hear from you. All of our activities for 2022 have begun—we are already working to prepare another event that exceeds the last one. Based on the positive feedback on AMUG 2021, that may be very hard to do, but hey, that’s been said before.

Hopefully, you have had a chance to enjoy some summertime with family and friends. Summer is typically a time for vacations and relaxing…not so much if you sit on the AMUG Board. We hope you have more opportunities to get away and enjoy some of the return to normal. If you have travels coming up, please be safe and enjoy!

Enjoy the summer before it’s gone!

My AMUG 2021 Experience

AMUG 2021…where to even begin?

To call it a life-changing experience may seem like the height of hubris, but it’s not far from the truth. But before we get there, it may behoove us to go back to the beginning.

I had applied for the Randy Stevens Scholarship in 2020 when I had a desktop FlashForge printer and zero clues. The 2020 scholarship was awarded to an incredible man, Chris Kaminsky, whom I’m now proud to call my friend. However, I’m not the type to give up, so as our program grew, I decided to reapply in 2021.

By this time, we had begun to see the value of using AM as an avenue for therapy for kids with extreme trauma. My students have all been removed from their homes and live in a residential treatment center where they receive intensive therapy for their experiences. They’re a mix of kids that have severe behavioral issues and that are juvenile sex offenders. My team and I have access to their records and their legal charges, but we rarely read these. We want to get to know the student, not their crimes. I choose to believe that no one is born bad, but unfortunate experiences can quickly steer a child in that direction. I also choose to believe that positive experiences can get that same child back on track to a healthy life.

I could go on and on, but we’re here to discuss my AMUG 2021 experience.

When Brett Charlton, AMUG Scholarship Committee chair, called me and told me I was chosen as the 2021 Randy Stevens winner, I was incredibly excited…for a week in Florida. I distinctly remember reading in one of the newsletters where Carl Dekker wrote, “AMUG is not a vacation in disguise.” “Sure, Carl, whatever you say,” I thought to myself.

Well, it turns out that Carl might know what he’s talking about. My fellow scholarship winner and friend, Sean Dobson, and I delivered our presentations on Tuesday of that week. I decided at the last minute that I would publicly admit, for the first time, that I am a survivor of sexual abuse, much like many of the students. I understand their trauma because I share it with them. I went on to describe how we’re using 3D design and printing to help our kids work through their feelings and to introduce them to a career path that is both rewarding and achievable. The rest of the week was a blur. I was on the move constantly—meeting people, learning, and making connections.

I’ll fully admit that I am well below noob status when it comes to AM. I learned a great deal about the industry of AM in my week in Florida. But, more importantly, I learned about the people in AM. Another thing Carl wrote about in the newsletters is that AMUG is about making connections. Once again, Carl proves himself prescient. I met so many good people who just want to help.

I’m currently working with several of them to grow our programs in directions I never thought possible. I’ve been empowered to reach out to anyone who will listen and ask for help for my kids. Our program is growing in directions I would have never dreamed of. Several incredible people have already stepped forward to help me attend AMUG 2022 in Chicago so that I might share what new projects we’re taking on and hopefully continue to grow my network.

No essay could possibly hope to capture what my experience at AMUG was like, so if you’d like to learn more about our kids and how we’re using AM to help, come find me in Chicago next year!

Chris Kaminsky: 2020 Randy Stevens Scholarship winner

My AMUG 2021 Experience

In early 2020, I saw a post from Zac Holcomb on LinkedIn that talked about a scholarship for AMUG 2020, and while I only had a couple of days to submit my entry, I got to work. It sent me back in time through everything I have done in life, including my most recent position as the Lakeshore Fab Lab manager. When you’re in the daytoday, you forget about the big picture, but by working on my entry, AMUG allowed me to see all the good that I’ve helped facilitate at the fab lab during my time there!

I honestly didn’t think I had a chance at winning, but I knew I wanted to attend the AMUG Conference, which wasn’t going to be in the budget for my department. A few weeks later, I found out that I had won, but then the victory was bittersweet because the world was shutting down due to the pandemic! I thought, “Just my luck!” Little did I know it would be a blessing in disguise.

The 2021 AMUG Conference offered me so much, including incredible friendships with the other 2020 and 2021 scholarship winners. Right off the bat, we all clicked. We arrived at the conference early in the weekend to start setting up and learning about what we would be doing throughout the week, and from the start, we bonded. When we weren’t volunteering somewhere, you would most likely see two, three, or four of us hanging out together. So thanks, 2020, for allowing us to all be together in the same year. Without the strife of 2020, we would not have bonded so closely, and the ‘Badge of Shame’ would not have been born! (The badge of shame, created by our little group, was awarded when someone accrued the most points for being late, forgetting something, or just dropping the ball).

I went to many sessions where I learned a lot about the additive world that I did not know before. I took back so much information and spilled it out to my team at the community college for weeks on end! One thing that we were told was to engage in everything; don’t just go to the workshops and sessions, also go to the social events and interact with everyone. I can say I was floating down the lazy river taste testing bourbon and whiskey with rocket scientists and leaders of this industry that I am passionate about. Nerd win.

Multiple times throughout the week, I would just be grabbing food, and people would come up from behind me and beg me to take their information because they wanted to help us at the fab lab. So, I now have direct contact info for some at SpaceX, NASA, and other places that are doing amazing things in additive. What other conference gives you those kinds of relationships?

We’ve all been to other industry conferences, and while great, there just isn’t this personal touch that I felt from AMUG. It truly is amazing. I want to thank everyone that made my AMUG journey possible through the Randy Stevens Scholarship. Randy’s passion and involvement in the AM community made it possible for me to go. And thanks to In’Tech Industries for keeping that passion alive via the scholarship. The education sector often gets left out of the professional world, and I think that is a huge mistake that we need to work on together.

Thank you to the AMUG Board and volunteers for truly an incredible event. I walked away with new friendships, industry contacts, and insights. And I got to live out a childhood dream of being in Harry Potter’s Diagon Alley holding a wizard’s wand!

Jordan Weston—Director, Education & Conference

I am both excited and humbled to be elected to the AMUG Board of Directors.

The very first AMUG Conference I attended was in Costa Mesa in 2012. The group had voted to expand the users group beyond SLA and SLS in the previous year, and the 2012 conference saw a then-record turnout of over 260 attendees. My, how things have changed!

Since that first year I attended, I was hooked. I was fascinated by the openness of the group, the networking, and the engagement through conversations. I was enamored with the sharing of information and knowledge, as well as the sense of community.

Each year that I attended, I was motivated to give back to the AMUG community what I had gotten out of attending. Over the years, I have volunteered as a speaker, moderator, track leader, liaison, and committee member. Along the way, I was privileged to work so closely with past and current board members, all of whom shared a passion for education and advancement in the AM industry. Through their mentorship, I was able to get a glimpse of the “behind the scenes” of AMUG, the year-round efforts, and incalculable volunteer hours that make it the success that it is, year after year. Through those interactions with the AMUG leadership team, it inspired me to continue increasing my contributions to this group that I’ve grown to cherish so much.

This year, I look forward to a new challenge. As Director of Education & Conference, I intend to work closely with the agenda committee, sponsors, and speakers to maintain the high-quality content and education that initially drew me into this group nearly a decade ago. I look forward to serving you and cannot wait to see you in Chicago next April!

Bill Macy—Director, Membership

AMUG has an important role in the maturation of 3D printing and AM. Early on, we gathered to discuss our challenges and collaborate on solutions. 30-plus years later, this mission is still being fulfilled!

In my roles as a user, consultant, and most recently an equipment manufacturer, this community continues to grow more important to me. It is critical that we are all accountable for the roles we support and the results we can produce as an AM community. Participation in a user community is vital; it was my time and my turn to contribute.

I am truly honored that the AMUG members gave me their vote of confidence to serve in this capacity. Thank you!

Tim Bell—Director, Business Development

Over the years of attending AM trade shows (about 15 years), I often found them to be nothing more than a way for the sales & marketing teams to generate leads. While there was always something new to learn and absorb, typically you were met in the booths by someone who can’t answer many technical questions. So, you would walk away with little more than a shiny brochure or trinket they printed.

And then I stumbled across AMUG—I think it was 2015 or maybe 2016—and I was blown away!

AMUG’s event is a gathering of people who share their experiences on success as well as failed builds, machine problems, materials they trust…and some they don’t. And I thought to myself, “WOW, this is amazing, and I want to be part of this!”

Well, here we are six years later, and I have gained the trust of the membership to take on the role of Director of Business Development.

I have spent many years doing business development. When I look at both the growth of AMUG and the members who attend the conference, I see many of the same people year after year. Wait, don’t get me wrong, I love these people and their support of the users group. But, I am positive that many users are hacking away at some 3D printer trying to solve problems in isolation. They need to know about us.

In my AMUG role, I am on a mission to bring those new members into our group to continue to build on the amazing work that has been done up until now!

TTM protects the factory floor from ESD occurrences with Essentium materials

In electronics factories like TTM Technologies, Inc. (TTM), one of the constant challenges is protecting products from electrostatic discharge (ESD) damage. TTM goes to great lengths to ensure that its factory floor is ESD-safe, including the procurement of electrostatically dissipative filament for all AM efforts.

Using its one-stop-shop approach to manufacturing, TTM needed an ESD-safe filament to print custom fixtures. Through trial and error, TTM discovered that most ESD-safe filaments on the market have a marring defect that results in scratching, streaking, or otherwise damaging parts or equipment during manufacturing.

Enter Essentium’s Z Collection of non-marring, electrostatically dissipative materials. These industrial-grade ESD-safe materials helped TTM ensure product quality to support its one-stop-shop manufacturing approach. Learn more here.

Additive Manufacturing

Does AM compete with conventional manufacturing? 3D-printed tooling says otherwise

Is AM in competition with other, more established manufacturing processes? Yes, because AM makes it possible to create shapes never before possible and to do so without the lead times and costs of many incumbent processes. But also no—in some ways, AM is actually advancing those conventional processes not by making parts directly but by providing the tooling these processes need.

3D printed tooling is the focus of the latest issue of Additive Manufacturing magazine, with stories covering its use for casting, injection molding, foam molding, low-temperature molding, assembly, and machining. Read the issue or subscribe.

AM experts offer advice to shops on adoption

Most manufacturers have heard stories about the myriad capabilities of AM. But for shops new to the technology that are more interested in what AM can do for them than in gee-whiz tales about the technology, they need to know the best way to get started with 3D printing and successfully integrate it into their conventional manufacturing operations. Representatives from Forerunner 3D Printing, Jabil, and Markforged offer tips for these shops in an article posted on The Additive Report website. (Read here.)
