Preassembled Turbojet Engine, 3D Printed in One Build: The Cool Parts Show #75
Stephanie Hendrixson | Additive ManufacturingTurbojet engines typically consist of hundreds or thousands of parts, but this engine — 2023 winner of The Cool Parts Showcase for Best Proof of Concept — was 3D printed as just two pieces, with the monolithic rotor embedded inside the stationary engine shell.
3D Printed Capo for Banjo Made With Binder Jetting not MIM: The Cool Parts Show #74
Peter Zelinski | Additive ManufacturingNew market, no mold tooling needed: Additive manufacturing via binder jetting enables a maker of guitar capos to expand to serve banjo players as well.
How 3D Printing Aids Sustainability for Semiconductor Equipment: The Cool Parts Show Bonus
Peter Zelinski | Additive ManufacturingHittech worked with its customer to replace fully machined semiconductor trays with trays made via DED by Norsk Titanium. The result is dramatic savings in tool consumption and material waste.
3D Printed Seal for Geothermal Power: The Cool Parts Show #73
Peter Zelinski | Additive ManufacturingPlugging a hole is a complex challenge when it’s a well for geothermal power. Additive manufacturing produces a shape-changing stainless steel seal for high-temperature applications deep underground.
3D Printed Titanium Replaces Aluminum for Unmanned Aircraft Wing Splice: The Cool Parts Show #72
Peter Zelinski | Additive ManufacturingRapid Plasma Deposition produces the near-net-shape preform for a newly designed wing splice for remotely piloted aircraft from General Atomics. The Cool Parts Show visits Norsk Titanium, where this part is made.

Peter Zelinski
Peter Zelinski helped to launch Additive Manufacturing in 2012. As the brand’s editor-in-chief, he is exploring the advance of 3D printing as a means of industrial production, increasingly including scale production. He is a regular speaker at the Additive Manufacturing Conference, and he is co-creator and co-host of a video series on 3D printing for part production, The Cool Parts Show, recently recognized in a national award for Best Use of Video in niche media. In 2020, Pete was co-host of the U.S. Air Force’s week-long event, the Advanced Manufacturing Olympics. Pete also serves as editor-in-chief of Modern Machine Shop, a sister publication focused on metalworking and CNC machining, and the magazine he has been part of since the late 90s. He holds a degree in mechanical engineering from the University of Cincinnati.
Stephanie Hendrixson
Stephanie (Monsanty) Hendrixson reports on 3D printing technology and applications as executive editor for Additive Manufacturing, and is also co-host of The Cool Parts Show, a video series that highlights unique, unusual and weird 3D printed parts. She got her start in manufacturing media in 2012, through an internship with AM's sister publication Modern Machine Shop, and continues to contribute to MMS as a guest blogger. Stephanie is a current co-ambassador for the Cincinnati chapter of Women in 3D Printing (Wi3DP). In 2019 she was named among Temboo’s 20 Women in Manufacturing That Are Influencing the Industry, and previously appeared in a panel discussion on “Digital Transformation: Gaining a Competitive Advantage with Data and Diversity” hosted by Women in Big Data at IMTS 2018.
