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. He has been writing about manufacturing technology for more than two decades, and he also serves of editor-in-chief of Modern Machine Shop, a sister publication focused on metalworking and CNC machining. He holds a degree in mechanical engineering from the University of Cincinnati.

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.

Video: 3D-Printed Brackets Are Key to Automated Coolant Delivery for Lights-Out Machining

An on-site look at the different elements of the coolant-delivery system developed by a machine shop committed to running unattended.

Design for Additive

Video: Additive Manufacturing Will Change How We Design

Geometric freedom is just the start. AM will also change how design happens.

Video: In Conventional Manufacturing, 3D Printing Is a Solution for Tooling

Tooling for conventional operations doesn't have to made conventionally. Rather than being made through machining, these welding fixtures are now made via 3D printing.

Metal 3D Printing in a Machine Shop? Ask the Marines

A hybrid system combining metal 3D printing with machining gives the Marine Corps perhaps its most effective resource yet for obtaining needed hardware in the field. It also offers an extreme version of the experience a machine shop might have in adding metal AM to its capabilities.

AMUG Conference Highlights Industrialization of Polymer 3D Printers

Exhibits at the conference this year included various examples of 3D printers being rethought and redesigned in pursuit of the speed, economy and reliability of industrial production. Polymer printers are leaving behind their roots in prototyping.

Education

2019 AMUG Conference Introduces Technical Training Lab Sessions

The largest version of the event so far gave technology suppliers a context for interactive deep-dive tutorials on their own products. It seemed to work.
