So I decided to build a 3d printer. I have been pouring over the RepRap documentation, and settled on the idea of building a RepStrap "seedling" based on recycled flat bed scanner parts.

I happened to be looking around a Hard OFF and found two identical scanners, perfect for X and Y axis.

I peeked down inside, and saw that they were belt driven by a geared down stepper motor. This should give a lot of torque, and higher resolution printing, at the expense of speed.

Also, they have a guide shaft on one side, and sit on a metal guide bar on the far end.

This class is taught by Yusuke Yumae of HotProceed.

The CupCake is a commercialized kit based upon the open source RepRap 3D printer. It can make parts, models, and machines using plastic fiber that has been melted and deposited by its robotic hand.

RepRap and CupCake "print" three dimensional parts!

Yusuke will demonstrate the part design and build process from start to finish.
