PolyJet

The PolyJet processes use a UV light to crosslink a photopolymer. A printer head jets tiny droplets of the photopolymer drawing the shape of each layer of the model and the supports needed to sustain it. The UV lamp attached to the printer head crosslinks the polymer and solidifies it.

The materials used are photosensitive resins that can also be combined together in the printing process.

 

Advantages:

  • Good precision and surface finish

  • Use of multiple materials and colors

     

Disadvantages:

  • Slow Build Process
