3DPOD: Insight from 3D Printing Pros

Eric Ronning started ReMixers when he and his team discovered a new way to more efficiently mix fluids, pastes, and other materials. Multiple materials could be more thoroughly mixed with new geometry. The ReMixers team then found that they could reduce waste in static mixer use. This led them to industrialize the production of millions of mixers using their own print farm. The team now uses several 3D printing technologies to produce 2K and other mixers at scale.

An Duong, a former Rolls-Royce innovation manager working on 3D printed aeroengines, made an unexpected shift from aerospace to entrepreneurship. The work was challenging and engaging, and he very much enjoyed his time at the company. But a side project creating desktop material extrusion models for display has now become his full-time job. We talk to An about his journey so far, how he makes his models, how he distributes them, and whether he can make a living from his company, Morethan3D.

Edvin Resebo has grown in LPBF as LPBF has grown, starting at Siemens and then the Alfred Nobel Science Park. Now he heads up AMEXCI, an effort to industrialize Additive Manufacturing. AMEXCI can design, optimize, test, and print parts from prototypes to volume production. Working across exacting industries, the firm is trying to take its partners Atlas Copco, Electrolux, ABB, Husqvarna, Hoganas, Saab, Scania, SKF, Stora Enso & Wartsila. But it works with other firms also in a collaborative approach that could be a method for other regions, clusters, or alliances to industrialize additive.

Alastair Jennings has been reviewing cameras for a very long time. A chance digression led him to review one of the first RepRap 3D printers. Since then, Alastair has reviewed many dozens of 3D printers over the years for various leading websites, national newspapers, and magazines. He has dozens of systems at home and uses them to make props, camera add-ons, and much more for his work at the local college, where he teaches. Alastair’s knowledge of desktop machines is deep and vast. At the same time, he is also honest and direct; he doesn’t mince his words. We talk to Alastair about the development of desktop 3D printers over the past decade, milestone 3D printers, good printers now, and much more. We talk about the current flock of systems in a very open way and hope that you appreciate Alastair’s deep insight and candor.

Rajeev Kulkarni was an early 3D Systems employee. He would spend 29 years at 3D Systems and was their VP of Corporate Strategy, CPO Printer Products, Manager of their Desktop Solutions business, VP of Global Engineering & R&D, and more. If we only discuss that storied career, we’d barely scratch the surface in this podcast. But, later Rajeev goes on to be on the board of Ackuretta, the board of Caracol, and is now the Chief Strategy Officer of Axtra3D. An hour was far far too short indeed. But, in that hour we got a lot of insight from Rajeev and I just know that this will be valuable to you.

Stefan Hermann is an engineer who spent 15 years at Liebherr Aerospace and Transportation. Rather surprisingly, he switched from making LPBF landing gear components possible & simulation to having his own YouTube Channel. CNCKitchen, therefore, was going to be a very different YouTube channel. And Stefan has taken his engineering rigor to desktop printers, material testing, 3D printing tips, layer height and part strength as well as 3D printer reviews. We talk about simulation, test, failure modes and much more with Stefan in an enlightening talk.

Jeff Thornburg has a wealth of experience, starting in the Air Force, Aerojet, NASA, SpaceX, and more. His experience in additive and space has now led him to start Portal Space Systems. Portal wants to make maneuverable satellites. This could be a real asset in case space is militarized, but even if it is not, more flexibility, different orbits, and additional capabilities could change what satellites can do. Taskable satellites and new propulsion systems can have a real impact on our planet and beyond. Jeff talks us through additive manufacturing in propulsion and why 3D printing in space is important.

3D printed suppressors are one of the largest and fastest-growing applications in 3D printing. Our colleague Scott Dunham first wrote a report on suppressors in 2017, before the boom, and we released another in 2024. But why exactly are suppressors in demand? And how does one make a good suppressor? To answer that, we spoke with Sean Bernstein, a former US Special Forces soldier with over 12 years of service in the Marine Corps. We talk about his remarkable journey to mastering CNC and 3D Printing. We learn a lot about suppressor design and what is important about suppressors. His company, Irregular Design Group, is using OneClick 3D printers to make an outstanding suppressor, and the future looks bright.
