Creating 3D Printers out of E-Waste

[jzatopa]

Really you only need 2 things to make a 3d printer, linear motion and motion control. There are steppers in a lot of different applications, I found one in an old floppy drive. If you can find enough of the right steppers and a way to drive them, a linear motion system can be cobbled together out of a lot of things. It is impressive that someone has already achieved this.
