What is polyjet 3d printing?

PolyJet 3D printing (also called PolyJet Matrix or just PolyJet) is a high-precision additive manufacturing technology developed by Stratasys. It works similarly to inkjet printing, but instead of depositing ink on paper, it jets tiny droplets of liquid photopolymer resin onto a build platform and instantly cures them with UV light, layer by layer.

Key Features of PolyJet Technology

1.How it works:

1.Multiple print heads jet photopolymer resin droplets (as small as 16–30 microns per layer).

2.UV lamps mounted on the print head immediately cure each layer.

3.Support material (usually a gel-like substance) is jetted simultaneously in areas that need support and is later removed (by hand, water jet, or dissolved).

2..Resolution & Surface Finish:

1.One of the highest-resolution 3D printing technologies available.

2.Layer thickness: typically 16–32 microns (0.016–0.032 mm).

3.Extremely smooth surfaces straight out of the printer — often comparable to injection molding.

3.Materials:

1.Wide range of photopolymers: rigid, rubber-like (Shore A hardness from 27–95), transparent, colored, biocompatible, high-temperature, and simulated ABS/PP.

2.Digital Materials: By jetting two or more base resins in different ratios at the voxel level, PolyJet can create hundreds of composite materials with varying hardness, color, or translucency in a single print (e.g., rigid parts with soft-touch overmolded grips).

4.Multi-material & Full-Color:

1.True multi-material printing in one job (unlike FDM or SLS).

2.Full-color capability (CMYK + white + clear) using Vero family resins — up to 500,000+ color combinations plus gradients and textures.

5.Typical Applications:

1.Highly detailed prototypes and visual models

2.Medical models (anatomical, surgical planning)

3.Consumer product design validation (appearance models)

4.Overmolding prototypes

5.Silicone molds (master patterns)

6.Jewelry and dental models
