The polyjet 3D printing process can be compared to an inkjet printing process. Finished components are of very high precision and individual layers can hardly be detected. Photopolymers (resin) are used as the material.
At the start of the printing process, liquid material is applied to a build platform by means of jets. Then the applied polymer layer is cured by UV light. After curing, the process is repeated, which step by step creates a component. As a rule, polyjet 3D printers have several jets so as to be able to apply various materials simultaneously. This permits components with different materials and different colours to be produced in one printing operation. The minimal layer thickness is only 0.016 mm or 16 μm.
This printing process is recommended above all for high-precision parts that require a very smooth surface. At the same time, the most varied colours even through to transparent parts are possible without additional processing stages.
