A glue gun that dispenses molten PLA instead of hot glue turned out to be a handy tool for joining 3D-printed objects together, once I had figured out how to print my own “glue” sticks out of PLA.

We continue our 3D printing discovery series by showing you how quick and easy it is to customize the size of pre-designed objects -- without ever going into a 3D design program.

D printing has come a long way since its invention in 1983 by Chuck Hull, who pioneered stereolithography, a technique that ...

The entire design is far too large to print as a single piece, so I divided the object into aluminum segments linked together by 3D printed parts. Here are the wireframe diagrams: ...

A new printing system called Forust is using scrap wood to 3D print wooden objects that are as structurally sound as regular carved wood.

How a 3D printer works can vary depending on the type of printing it's doing. Use this guide to understand the variations in materials and technique.

The 3D printing process turns a whole object into thousands of tiny little slices, then makes it from the bottom-up, slice by slice. Those tiny layers stick together to form a solid object.

3D printing transforms spools of plastic filament or trays of resin into physical objects. 3D printing is quite literally out of this world.

It's difficult to build devices that replicate the fluid, precise motion of humans, but that might change if we could pull a few (literal) strings. At least, that's the idea behind "cable-driven ...

A new 3D printing technique suspends the object being built in a gel to eliminate the need for structural supports that must be somehow etched away after the build process is complete.
