PolyJet is technology for 3D printing that produces smooth, precise parts, prototypes, and tooling. Any PolyJet 3D Printer provides sharp precision, smooth surfaces, and ultra-fine details. Even the most advanced PolyJet systems can mimic anything from plastics and rubber to human tissue and create a full spectrum of colors by mixing various photopolymers at specific concentrations and microstructures.

Working of PJ 3D Printing

Jetting heads are at the heart of PolyJet printers. By sliding to and fro along the X-axis, the jetting heads deposit a single layer of the construction material (typically photopolymers). The depth of each photopolymer layer deposited by each jetting head is selectively software-controlled. The ability to generate precise models is provided by Raster scanning the head around the build platform.

There are several ways that PolyJet printers operate, but spraying a liquid photopolymer from a multi-nozzle, inkjet-style print head is one of the most common techniques. They are immediately cured and hardened by UV light as soon as the droplets of these liquid photopolymers are discarded. The build platform drops along the Z-axis once a layer is complete, and the next layer of photopolymers is ejected from the heads. Until the object is complete, the procedure is repeated. The raw material is contained in cartridges and connected to the nozzles directly.
