Can My Machine Tool Access My Support Structures?

Analyzing the machinability of support structures opens a new way of thinking about optimal build orientation.

Basics

Understanding Surface Finish of Metal 3D-Printed Parts

Additive manufacturing imposes inherent manufacturing and design challenges that impact the dimensions and tolerances that you can (or cannot) achieve on an “as built” part.

How Machining Support Structures Affects the Cutting Tool

Studies show that thin-walled additively manufactured support structures may be more challenging to machine than they might appear.

How Machinable Are Support Structures in a Metal 3D-Printed Part?

What happens when you cut away thin-walled supports on your metal 3D-printed part?

Basics

Finding the Value Proposition for Additive Manufacturing

Why would anyone want to use additive manufacturing?

Postprocessing

Postprocessing Steps and Costs for Metal 3D Printing

When your metal part is done 3D printing, you just pull it out of the machine and start using it, right? Not even close.

Basics

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

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

Basics

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.

Lightweighting with Lattices

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

Prototyping

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.
