Also known as: multijet modeling, polyjetting, multijetting, jetted photopolymer
Polyjet is a versatile 3D printing process that is used to create smooth, detailed prototypes that look and feel like the end-product. Polyjet can be used to create rubber-like and multi-material models in one print.
An inkjet printhead sprays liquid drops of a photopolymer onto a build platform. The drops are immediately cured by a UV light and the model is built up layer by layer with the solidified droplets.
After parts are removed from the machine, they are water-jetted to remove excess support.
Polyjet has a good layer resolution and surface finish, making it a good choice for user testing models and visual prototypes. However, the material properties are not stable over time and it is not suitable for end-use parts. In addition, designers must take care when designing fragile pieces on polyjet parts as the models are waterjetted to remove the waxy support material and delicate features will likely break.
