Peter Zelinski Editor-in-Chief

Peter Zelinski is the founding editor of Additive Manufacturing magazine and Additive Manufacturing Media, which for over 10 years has reported on industrial 3D printing and its adoption by manufacturers. As the brand’s editor-in-chief, Pete is exploring the advance of 3D printing as a means of production, and the ways it is changing both part design and manufacturing enterprises. He has been a regular speaker at the Additive Manufacturing Conference, which is now the Formnext Forum, and he is co-creator and co-host of the video series on 3D printing for part production, The Cool Parts Show — a show that has been honored with a national award for Best Use of Video in niche media. He is a podcaster, appearing regularly with Additive Manufacturing Media colleagues in AM Radio, and he has also appeared in a sister podcast, Made in the USA. In 2020, he was co-host of the U.S. Air Force’s week-long event aimed at manufacturing for military readiness and sustainment, the Advanced Manufacturing Olympics. Pete also serves as editorial director of Modern Machine Shop, a sister publication focused on metalworking and CNC machining, and the magazine he has been part of for over 25 years. He holds a degree in mechanical engineering from the University of Cincinnati.

Ultra-Complex 3D Printed Scaffolds Enable Cell Growth: The Cool Parts Show #70

Perhaps the ultimate surface-area challenge is in bioengineering: creating structures that can grow sufficient cells within a compact volume to be effective for leading-edge medical treatments. The Southwest Research Institute develops bioreactor scaffolds that could only be made using 3D printing.

6 Cutting Tools for Machining Made Via 3D Printing

By making tools, additive manufacturing aids so-called “subtractive” manufacturing (better known as machining). Here are examples of how 3D printing balances performance, coolant flow and weight in small and large cutting tools.
