PolyJet is a 3D printing technology developed by Stratasys. It is an additive manufacturing process that allows for the creation of high-resolution, multi-material, and multi-color parts. PolyJet technology utilizes inkjet printheads to jet and layer ultra-thin droplets of liquid photopolymer materials onto a build tray.

The process begins with the selection of the desired materials, which can include rigid, flexible, transparent, or rubber-like options. These materials are loaded into the 3D printer as liquid photopolymers. The printer then jets these materials in precise patterns onto the build tray, layer by layer.

Each layer of photopolymer material is cured instantly using UV light as it is jetted, resulting in the solidification of the material. By jetting different materials simultaneously, PolyJet technology enables the creation of parts with varying material properties, colors, and textures within a single print.

PolyJet 3D printers can produce highly detailed and complex parts with smooth surfaces. They are particularly suitable for applications that require intricate features, fine details, and realistic textures. The ability to use multiple materials in a single print allows for the fabrication of prototypes, models, and functional parts that closely resemble the properties of the intended final product.
