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 Your CEO Needs to Know About Additive Manufacturing

Additive manufacturing promises to affect far more than manufacturing alone. When evaluating AM, the perspective needed is the view that sees the impacts all across the enterprise.

Video: Support Structures Are Misnamed! How to Understand Anchors in Additive Manufacturing

Supports or anchors can account for a significant share of both the engineering investment and material use in metal additive manufacturing. Michael Hansen of SLM Solutions discusses the role and importance of support structures.

Video: Metal AM Affects Plastics Production via Conformal Cooling

Additive manufacturing allows cooling channels within mold tooling inserts to follow the form of the tool rather than being straight drilled holes. Here’s why this matters.

Video: The Impact of Part Orientation on Cost and Build Time in AM

A different build orientation might mean fewer layers and less support structure, though the part might need to be redesigned to take advantage of this different orientation.

Why Robots and Additive Manufacturing Go Together

3D printing and robots enable one another. We miss the possibilities of one if we do not consider the other. The combination includes AM for end effectors, robots for 3D printing parts, and different modes of metal and plastic production.

Video: How Simulation Assists Directed Energy Deposition

Scrapping an AM part is potentially as costly as scrapping a machined part. Directed energy deposition is an additive process that can benefit from a resource that safeguards machining: simulation software.

Video: What is Directed Energy Deposition?

DED is an additive manufacturing process that builds features or parts in metal by placing material where needed.

Robot Is Production Solution for Laser Metal Deposition

The move from prototyping to production might involve a move from machine tool to robot, but development work between Formalloy and the robot suppliers means the process and programming do not have to change.

The Promise of Robotic Metal Additive Manufacturing

Addere’s robot-based laser system builds using standard weld wire. The company was spawned from a robot integrator, and that background has been valuable for both overcoming the challenges and perceiving the possibilities of using a robot for metal 3D printing.

Video: Survey of AM Users Finds Machine Shops Employing 3D Printing for Plastic Part Production

Additive manufacturing provides an option for low-quantity production in polymer. One implication is that machine shops are liable to be less strictly metalworking businesses.
