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: 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.
