Explore the mechanics of a 3D printer through detailed animations and explanations. This video reveals the fundamental ...

Fast-forward a decade, and the world of 3D printing has evolved tremendously. Printers are faster, smarter, and more refined.

Currently, 3-D metal printers work a bit like a computer-driven milling machine, a standard manufacturing tool in high-precision metal parts making, TechCrunch explains.

This 3-D printer can fit in the palm of your hand The proof-of-concept device is a step toward making the technology more portable This prototype 3-D printer is roughly as long as a quarter is wide.
