Video: More Than Just 3D Printing—An Additive Manufacturing Conference Recap

Editor-in-Chief Peter Zelinski and Senior Editor Stephanie Hendrixson cover the extent to which additive manufacturing is closing in on production as well as their impressions from the first full day of the 2019 Additive Manufacturing Conference + Expo.

Video: Topology Optimization versus Generative Design

Why do these strategies matter in design for additive manufacturing (DFAM), and what’s the difference? A conversation with PADT’s Eric Miller explores AM and design, including its human element.

Video: Controlled Porosity Can Be Functional Advantage Realized via 3D Printing

A wall of metal that looks solid is actually 90% dense, allowing gas to pass through. Mold venting is one application.

Video: The STL File Can Produce Surface Defects in 3D-Printed Parts

Timothy Simpson of Penn State University discusses the influence of model definition in additive manufacturing and what to do about its effects.

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.

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.

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.

Video: Periscope Case Shows 3D Printing for Niche Manufacturing

Manufacturing without mold tooling allows the production quantity to be tailored to the market size.
