Build your own 3D printer with a $200 kit

Posted on May 22, 2014 by robertwilkie

Oh and another $30 for shipping, oh and you need a heated bed.  It looks promising, and could be a good way to start into 3D printing.  Personally, I am waiting for some reviews on it before doing anything. http://store.quintessentialuniversalbuildingdevice.com/
