Video: This Custom Part Illustrates the Promise of Polymer 3D Printing

A low-quantity plastic part used instead of metal components saved weight for a motorcycle. The application illustrates the expanding opportunities for polymer manufacturing.

Metal AM

Video: HP on Additive Manufacturing for Production

HP’s Timothy Weber discusses VW’s plans for making metal parts via AM and the way forward to implementing additive as a production process.

Metal 3D Printing in a Machine Shop? Ask the Marines

A hybrid system combining metal 3D printing with machining gives the Marine Corps perhaps its most effective resource yet for obtaining needed hardware in the field. It also offers an extreme version of the experience a machine shop might have in adding metal AM to its capabilities.

AMUG Conference Highlights Industrialization of Polymer 3D Printers

Exhibits at the conference this year included various examples of 3D printers being rethought and redesigned in pursuit of the speed, economy and reliability of industrial production. Polymer printers are leaving behind their roots in prototyping.

Education

2019 AMUG Conference Introduces Technical Training Lab Sessions

The largest version of the event so far gave technology suppliers a context for interactive deep-dive tutorials on their own products. It seemed to work.

Video: Selective Laser Sintering for Production of Large Parts

SLS offers a production option enabling large, precise plastic parts to be made cost-effectively in quantities generally too low for injection molding.

Basics

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.

How a Solid-State Process Stood Firm Until Additive’s Moment

Early on, this company saw the promise of friction stir welding for building forms in layers. Few understood at the time. They understand now, in part because this process offers benefits such as blended materials and freedom from stress that other metal AM approaches can’t match.

Tooling

Video: The Pella Corporation Is Succeeding With 3D-Printed Tooling

An engineering leader with the window and door maker shows examples of the tooling and machine parts now produced for the company's manufacturing processes using 3D printing.
