Photopolymer Jetting (Polyjet)

Inkjet print heads are used to jet liquid photopolymers onto a build platform. The material is immediately cured by UV lamps and solidified which allows to build layers on top of each other.

Advantages:

  • Multiple materials can be jetted together allowing multi-material and multi-color parts
  • Functionally graded materials are possible.
  • Multi-material and/or multi-color parts
  • Can achieve good accuracy and surface finishes

Disadvantages:

  • Does not work with standard materials but with UV-active photopolymers which are not durable over time (thermoset)
  • Works with UV-active photopolymers. Therefore, parts are not durable over time and have limited mechanical properties
