Jump to Section
PolyJet is an industrial 3D printing process that builds multi-material prototypes with flexible features and complex parts with intricate geometries in as fast as 1 day. A range of hardnesses (durometers) are available, which work well for components with elastomeric features like gaskets, seals, and housings.
Common applications for PolyJet 3D printing:
- prototyping designs for overmolding or silicone rubber parts
- combining two colors or durometers into a single part
- simulating elastomers or flexible parts
PolyJet Design Guidelines and Capabilities
Our basic guidelines for PolyJet include important design considerations to help improve part manufacturability, enhance cosmetic appearance, and reduce overall production time.
| US | Metric | |
| Maximum Part Size | 19.3 in. x 15.4 in. x 7.9 in. | 490mm x 390mm x 200mm |
| Layer Thickness | 0.00118 in. | 30 microns |
| Minimum Feature Size | 0.012 in. | 0.3mm |
| Minimum Freestanding Wall, Hole, or Channel Size | 0.030 in. | 0.76mm |
Tolerances for PolyJet: For well-designed parts, tolerances of ±0.005 (0.1mm) for the first inch plus 0.1% of nominal length can typically be achieved. Note that tolerances may change depending on part geometry.
PolyJet Material Options
PolyJet provides the ability to choose a desired hardness or combine material properties into a single build, which makes it ideal for prototyping overmolding parts. Shore A hardnesses of 30A, 40A, 50A, 60A, 70A, 85A, 95A, and rigid are available in these colors:
- Digital Clear/Translucent
- Digital Black
- Digital White
