PolyJet technology, marketed in the US by Stratasys, is a relative newcomer to the RP industry. However, it is gaining ground rapidly for concept modeling applications. It is in the class of 3D printers that use multiple jets imaging in raster fashion to deposit UV-curable liquid. The supports are gelatinous and can be torn and jetted away with reasonable effort. Available systems use a remarkably thin layer thickness, which gives them great Z-axis resolution, but the X and Y resolution are significantly less impressive. Also, since they are raster-based, the parts look a bit rough. FineLine does not offer this service.
