Most 3D printers use stepper motors to control the movement of the extruder head. If you could actually print those motors it would be one more big step toward self-replicating hardware. Now obviously ...

TMC2209 is a stepper motor driver chip from German firm Trinamic that I suspect folk interested in the insides of 3D printers will be hearing a lot more about in the near future. In many printers, the ...

There’s a seemingly unending list of modifications or upgrades you can make to a 3D printer. Most revolve around the mechanical side of things, many are simple prints or small add-ons. This upgrade is ...

MIT researchers built a 3D printer that can produce a fully functioning electric linear motor in about three hours for 50 cents in materials. Linear motors are typically used in optical systems and ...
