Peter Zelinski Editor-in-Chief

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, The Cool Parts Show, which showcases interesting 3D printed end-use parts. In 2020, the series won Niche Media’s award for Best Use of Video. 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. A writer in his free time as well, he is the author of books on theology, and more recently of an e-book offering a reader’s appreciation of printed books, e-books and how they differ. He holds a degree in mechanical engineering from the University of Cincinnati.
