What is a 3D printer and what is the PolyJet?
The PolyJet 3D printer technology "jets" out a liquid photopolymer resin that is held within the 3D printer head block via a slight vacuum. A 3-Dimensional image designed on a computer is "sliced" up into many 2-Dimensional bitmap images, basically resembling an image you print to your normal printer at home, or in the office. Each 2D layer is jetted down, one on top of another, in an additive process called "Rapid Prototyping". Jetting liquid material out of the print heads allow fine control of jetting onto a medium controlled tightly via system control hardware and software. Hence, PolyJet 3D printer technology produces 3D models with superior sidewalls and downward facing surfaces.

PolyJet 3D Printer Advantages
- High quality: Market-leading resolution of 16µ ensures smooth, accurate and highly detailed 3D models.
- Highly accurate: Precise jetting and material properties enables fine details and thin walls of the 3D model.
- Fast: Rapid 3D printer process with high-speed raster build at full width, simultaneous building of multiple items, and no post-curing with minimal post processing speeds Research & Development goals.
- Versatile: The wide variety of FullCure PolyJet materials enables 3D models with different geometries, mechanical properties, and colors.
PolyJet™ Technology – 3-Dimensional Printing Applications
Kaiser3D continues to push the technology envelope in order to bring PolyJet based high resolution 3D printing into the reach of an ever-broader range of companies and professionals.
Applications for the PolyJet 3D Printing are:
- Engineering Models for review and product development - Static and interactive 3D models used to convey conceptual design and marketability.
- Functional Testing - There are different PolyJet resins to meet each specific functional demand for parts and assemblies used for design and engineering purposes, including fit-check and functional testing.
- Molding & Casting applications - 3D models used to create impressions and cavities in temporary tooling to secondarily cast or mold plastic or metal parts. Also, 3D models used as master patterns for direct foundry burnout in some cases.
- Rapid Manufacturing - Production of end-use plastic components and assemblies directly from a rapid prototype machine.
