Most of us are familiar with the PolyJet 3D printers by Stratasys. They are high quality, very expensive polymer jetting machines that utilize UV likes to cure a liquid resin. These printers are so pricey that they are reserved mostly for large companies. One man, name David Feintrenie is in the process of developing an affordable polymer jetting 3D printer, and it costs less than $2000 to build. While it is not yet capable to coming close to the quality of the Stratasys PolyJet 3D printers, Feintrenie hopes to get it there soon.
