One of my first discoveries about 3D printing was the large number of mostly-free objects people have designed and made available for you to simply download and print. You don't have to have an iota ...

Maybe the “printer” part of “3D printer” is not exactly the right word, since printing has so long been thought of as a two-dimensional process of applying ink to paper. But the term, like the 3D ...

3D printing creates solid objects from the additive process of layering plastics, metal, wood, synthetic fibers, and more. You can 3D-print your own designs using a ...

Explore 3D printing in robotics for custom, lightweight parts, rapid prototyping, and on-demand spare components.

It's a frustrating limitation of 3D printing: Printed objects must be smaller than the machine making them. Huge machines are impractical for printing large parts because they take up too much space ...

A 3D printer cannot make any object on demand like the "Star Trek" replicators of science fiction. But a growing array of 3D printing machines has already begun to revolutionize the business of making ...
