This small desktop machine is built inside a 300mm cube of 20mm extrusion. Work area is 14cm by 14cm. I used 400 step nema17 motors all around.

Designed from the ground up as a low cost, highly scalable delta printer. This printer has been built as small as carry on luggage size, up to an 18in wide print surface and is capable of larger. Approximate cost is low to mid $500 range start to finish, including electronics for a basic model.
