3D Printed Stepper Motor... kind of.

For those who don't know, a stepper motor is the basic muscle of a 3D printer. Instead of other motors which are basically "on = go, off = stop" a stepper motor is told how far to move and it does, which makes it perfect for, say, telling the arm of a 3D printer to go to a specific location and start drawing.

This iteration is rough to say the least. Basically it's a frame that you can use homemade windings and electronics to make a stepper motor with. It's got a minimum step of 7.5 degrees, which is rough but it's a start and could be geared down. Talk on Reddit about making it more 3D printed is encouraging, but until someone undertakes to do something it's all just talk. I don't know if this stepper is significantly cheaper than just buying a stepper motor either. But it's exciting nonetheless. 105% cool.

  1. Such a cool idea. I would give it a "150% cool" Joe.
