Technology Overview

Material jetting is similar to inkjet document printing, but instead of jetting drops of ink onto paper, PolyJet 3D printers jet drops of liquid photopolymer onto the build tray.  Multiple print heads jet material simultaneously to create each layer, and UV light is then used to cure the layers.  These layers build up one at a time in an additive process to create a 3D model.  Fully cured models can be handled and used immediately without additional post-curing.  Along with the selected model materials, a gel-like support material facilitates successful printing of complicated geometries. Support material can be removed by hand or by a high-powered water jet station.

Material jetting is the only additive manufacturing technology that can combine different print materials within the same 3D printed model in the same print job.  Additionally, the multi-material printing process is capable of constructing functional assemblies, which reduces the need for multiple builds.
