Are Emissions from 3D Printing Hazardous to Your Health?

And if so, what can you do about it? NIOSH researchers share the organization’s approach to eliminate, avoid and reduce operator contact with volatile organic compounds (VOCs) and ultrafine particles from fused filament fabrication (FFF) 3D printers.

Video: 3 Roles for Simulation in Additive Manufacturing

This conversation with PADT’s Eric Miller explores how simulation and 3D printing work together at three distinct stages in additive manufacturing, for DFAM and beyond.  

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: 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.

Additive Manufacturing via Material Extrusion

Material extrusion was the second process to be successfully commercialized. After three decades of material advancements and a diverse array of start-ups and applications, the use cases for this technology are still going strong.
