Why Does My 3D-Printed Part Cost So Much?

The machine, the facility and the material are just three costs behind the price tag.


With Additive Manufacturing, No Tooling Is Required

In conventional manufacturing methods, tooling can easily cost hundreds of thousands of dollars. With AM, you print as needed, no jigs, fixtures or tooling required.

Design for Additive

AM Enables Manufacturing for Design, Not the Other Way Around

Additive manufacturing allows us to make any shape we want, without having to adapt the design for the manufacturing process.

Metal AM

Lightweighting with Lattices

Building components as a network of unit cells may improve material utilization and performance. 


Benefits of Additive Manufacturing in Functional Prototyping

Additive manufacturing enables companies to build functional prototypes faster, allowing for more iterations and better designs. 


Are AM Parts as Strong as Those Made Conventionally?

An additively manufactured flight-critical helicopter part indicates that they are.


Removing Metal Supports from AM Parts

What is the best way to remove metal support structures from AM parts?


Will My AM Part Explode?

Will my additive manufactured part explode? Not if you’re careful. Postprocessing parts built from metallic powder requires extra precautions.


Easing into AM

A layered approach to learning the technology behind additive manufacturing (AM) will help lessen the headaches.


Where Do I Start with Additive Manufacturing?

Here are a few basic questions to ask yourself before diving in.

Wanted: Flexible Shops and Open-Minded Pros

AM is more complicated than the hype implies. It needs creative people to advance its adoption in this industry.
