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.

Video: What is Directed Energy Deposition?

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

AM 101: Multi Jet Fusion (MJF)

From functional prototypes to end-use parts, HP’s Multi Jet Fusion (MJF) is capable of efficient production. Learn about MJF, including its materials, postprocessing requirements, benefits and more, in this 101 post.

AM 101: Continuous Liquid Interface Production (CLIP)

Continuous Liquid Interface Production (CLIP) is the key to Carbon's Digital Light Synthesis. Here's a look at how it works and how it differs from stereolithography.

To Succeed With Additive, See It As More Than Just Another Method of Making Parts

A fundamental challenge of AM relates to mindset: recognizing it as not just a manufacturing method but also a choice with far-reaching impacts.

What Is Directed Energy Deposition?

Analyzing directed energy deposition and powder-bed fusion provides a thorough understanding of the extra machining necessary for a “near-net shape” versus a “net shape” manufacturing process.

AM 101: Binder Jetting

Binder jetting requires no support structures, is accurate and repeatable, and is said to eliminate dimensional distortion problems common in some high-heat 3D technologies. Here is a look at how binder jetting works and its benefits for additive manufacturing.
