PolyJet 3D printing technology is a powerful additive manufacturing method patented by Stratasys. 3D printers powered by PolyJet technology feature 16-micron layers with accuracy as high as 0.1 mm for smooth surfaces, thin walls and complex geometries. It is the only technology that supports a range of materials with properties from rubber to rigid and transparent to opaque. And with Objet Connex technology, multiple materials can even be printed simultaneously in the same part.
PolyJet 3D printing is similar to inkjet document printing. But instead of jetting drops of ink onto paper, PolyJet 3D printers jet layers of liquid photopolymer onto a build tray and cure them with UV light. The layers build up one at a time to create a 3D model or prototype. Fully cured models can be handled and used immediately, without additional post-curing. Along with the selected model materials, the 3D printer also jets a gel-like support material specially designed to uphold overhangs and complicated geometries. It is easily removed by hand and with water.
PolyJet 3D printing technology has many advantages for rapid prototyping, including superior quality and speed, high precision, and a very wide variety of materials. Based on PolyJet technology, Objet Connex 3D Printers from Stratasys are the only additive manufacturing systems that can combine different 3D printing materials within the same 3D printed model, in the same print job.
