Design Guidelines: PolyJet

Our basic guidelines for PolyJet include important design considerations to help improve part manufacturability, enhance cosmetic appearance, and reduce overall production time.

Size

Accuracy

For well-designed parts, tolerances of ±0.005 (0.1mm) for the first inch plus ±0.001 in./in. (0.001mm/mm) for each additional inch can typically be achieved. Note that tolerances may change depending on part geometry.

Minimum free-standing wall or feature is 0.030 in. (0.76mm). Holes, channels, and slots less than 0.030 in (0.76mm) in diameter/width will not form; maximum length-to-width aspect ratio is 4:1.

Materials

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
