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 the co-creator and co-host of a video series, The Cool Parts Show, which showcases interesting 3D printed production parts. 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.

Shoe Insoles Precisely Tailored to Individual Feet: The Cool Parts Show S1E4

This episode of the The Cool Parts Show looks at how 3D printing will deliver tailored products. Scanning feet for their geometry and pressure enables Aetrex and EOS to manufacture insoles that are unique to individual wearers.

Aerospace

What Is the Role for Additive Manufacturing in Aircraft Structural Components?

Spirit AeroSystems recently began installing the Boeing 787’s first titanium structural component to be made through AM. The part is not critical but also not minor. I spoke with manufacturing leaders at Spirit about the meaning of the part and the way forward for additive in aircraft structures.
