One could say that the PolyJet process is a development of the SLA-process. A photopolymer fluid is sprayed according to a geometry generated by an STL- file, just like a dot-matrix printer. The layer is then cured immediately after being sprayed by ultraviolet light. The support material is sprayed out at the same time but this is not hardened by the UV light it has a more gel like consistency. Machines that utilise this process tend to be much faster when compared to other free form methods.
The thickness of the polymer layer is adjustable from 0.016 to 0.030 mm, which is amongst the best the market has to offer at the current time. Such fine layers naturally result in the finish offered by this method being outstanding.
Advantages: Extremely fine surface and high accuracy. Check out how our new polyjet Connex 500 works!
