What is PolyJet 3D Printing？

PolyJet 3D is a 3D printing technology known for its customizable material properties and excellent surface finish. Similar to inkjet printing, it operates by spraying UV curable resin onto a build tray. One of the most cutting-edge industrial 3D printing options available, PolyJet 3D printing creates parts with exceptional accuracy and speed. Additionally, it supports a wide range of building materials.

How Does PolyJet 3D Printing Work?

In the beginning of the PolyJet procedure, tiny droplets of liquid photopolymers are sprayed in layers that are quickly UV cured. During construction, voxels (three-dimensional pixels) are strategically positioned to enable the combination of flexible and rigid photopolymers, or digital materials. The vertical thickness of each voxel is 30 microns, which is the same as the layer thickness. On the build platform, the thin layers of digital materials stack up to produce precise 3D-printed items.

During the build, each PolyJet item is entirely covered with support material, which is then manually removed using a chemical solution bath and a pressurized water stream. Following the production procedure, no post-curing is necessary.

Benefits of Polyjet 3D Printing

PolyJet is renowned for its adaptable material characteristics and superior surface quality, producing prototypes that are smooth and detailed. With the help of numerous photopolymer alternatives, PolyJet enables manufacturers to replicate a wide range of distinct end-use materials. Rapid prototyping is made popular by the PolyJet manufacturing process's high CAD file accuracy and overmolding capability.

Common applications for PolyJet 3D printing

prototyping designs for overmolding or silicone rubber parts

combining two colors or durometers into a single part

simulating elastomers or flexible parts
