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 of 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.

8 Cool Parts from Formnext 2019: The Cool Parts Show Special Edition

Editors Peter Zelinski and Stephanie Hendrixson attended Formnext 2019 in Frankfurt, Germany. Here are 8 cool 3D printed parts spotted on the show floor. 

Metal AM

Formnext 2019 Emphasizes Complete Additive Manufacturing Process Chain — Well Beyond 3D Printing

The biggest AM event gets bigger. The sophistication of attendees advances. Materials, digital tools and postprocessing are prominent. Here are 10 impressions of this year’s show.

Education

“The Cool Parts Show” Season One Now Complete: Here is Why We Launched the Show and How You Can Help

Our YouTube series showcases the parts and possibilities additive manufacturing is making real. Will you help us reach future AM users?

Tooling

AM Is Advancing into Tools for Machining: Examples from EMO

The design freedom of additive manufacturing delivers increased performance to tools used in subtractive processes. At the world’s leading exposition for machine tools, I saw various examples of this.

AM Technology

Largest ExOne Metal Binder Jetting System Yet Provides 160-Liter Build Volume

The design of this machine anticipates scale production, with compaction technology for repeatable part density and Industry 4.0 connectivity for lightly staffed AM factories.

Metal AM

Can 3D Printing Make a Better AM Build Plate? The Cool Parts Show S1E5

Ultrasonic metal additive manufacturing was used to create a build plate aimed at making powder bed fusion more effective. This episode of The Cool Parts Show looks at a part by AM, for AM.

The Cool Parts Show

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

The Cool Parts Show, Episode 1: This Rocket Fuel Injector Is a Solid Part That Contains a Working Motor

Our new video series debuts with a look at a solid metal part made through additive manufacturing that was built with a motor embedded inside. The motor sealed within the part adjusts the rocket’s fuel mixture while the rocket is in flight.

Metal AM

Velo3D: Avoiding Support Structures Means Metal AM Can Be a Solution for Direct Part Replacement

Because of the extent of the redesign they might call for, support structures can be an impediment to AM adoption. Reducing the need for support structures increases the viability of 3D printing for current parts.

Automotive

Video: Additive Manufacturing Expands Design Possibilities for Automotive Lighting

Automotive lighting maker Varroc Lighting Systems describes the impact 3D printing instead of injection molding will have on car features such as headlights.

Production

As 3D Printing for Production Becomes Practical, the Attention in Materials Shifts to Practical Concerns

Recent posts relate to ensuring sufficient materials supply for production, certifying processes for AM materials, and even whether the properties of polymer AM include the ability to hold a screw.

Materials

AM at Jabil: From 3D Printing Materials to Distributed Manufacturing

One of the largest manufacturers in the world has made a significant investment in 3D printing — both as a user and an advancer of this technology. Our original reporting dives into the what and why of additive manufacturing at Jabil.
