There are a few delta bot 3D printers out there such as the Rostock which, while being a very nice printer, is still a little expensive. When [Shai] from SUNY wanted to use a 3D printer for his artistic and academic pursuits, he decided to build his own printer. Thus the Deltaprintr was born.

Instead of printed parts, the Deltaprintr uses laser cut and machined parts for just about all of its bill of materials. The three motors mounted in the base are connected to the delta arms with Spectra fishing line, thus getting rid of the ludicrous cost of belts of the requisite length.

Everything is Open Source, and the guys behind the project should be putting their printr up on Kickstarter sometime next month. Word is the entire thing should be sub-$500, and a little bit of guessing tells me that doesn’t mean $499.
