3D printing is everywhere these days. People use it to make everything from product prototypes to jet engines, and everything in between — but how do 3D printers work, exactly?

Learn what a 3D printer is, how it works, and how much it costs. 3D printing is helpful for personal use, prototyping and manufacturing.

All 3D printers on the market today are, at least primarily, additive. That is to say, they work by precisely depositing more and more of a building material, creating an object up out of nothing.

Although 3D printers use a variety of technologies and can print from materials ranging from titanium to chocolate to living cells, they have one thing in common: the ability to produce a physical ...

A 3D printer is one that can create three-dimensional objects. The printing process works by dripping tiny beads of hot plastic on top of one another, following a pattern laid out by the blueprint ...

NASA and Made in Space have teamed up to build a 3D printer that works in zero gravity. They plan on shipping it up to the International Space Station late next year.

Some readers may consider that a revolting oversimplification, but it is a helpful one to make a point about how 3D scanning, 3D printing, and CAD work do (and don’t) work together.

The Bambu Lab H2S rounds out the company's current selection of 3D printers nicely. It's fast -- nearly a third faster than ...
