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.
Austin Grogan
Austin joined Gardner Business Media's Custom Content Team in 2017 as the company's first videographer. He works with all 12 brands creating engaging editorial and marketing video content for various segments of the manufacturing industry. To put it in a lighter sense, Austin aims to find the beauty in manufacturing and combine it with technical knowledge for both old and new generations to enjoy through an expanding digital platform. Austin graduated from Ball State University with a B.A. in video production. He spends most of his time immersing himself in geek culture and discovering new hobbies related to that culture.

Directed Energy Deposition (DED) Error Turns Nozzle Into Chess Piece — AM: Why the Failure? #3
Chess pieces are often 3D printed as demo parts, but this one was an accident! What happened? The answer involves heat transfer.
Metal 3D Printed Part Should Be Flat, Has Bubble — AM: Why the Failure? #1
What should have been a straightforward application of laser powder bed fusion to make a simple component in 316L stainless steel turned into a printing fail. See why the failure happened.
Metal 3D Printed Part Has Unplanned Feature, Not Part of the Design — AM: Why the Failure? #2
This component for the oil and gas industry features a shelf through the lattice structure that does not appear in the CAD model. How did it get there? The answer does not involve STL, but we talk about that anyway.
