About the Process

PolyJet is a 3D printing technology 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 instantly cure them with UV light. The layers build up to create a precise 3D model or prototype.

Along with the selected model materials, the PolyJet 3D printer also jets a gel-like support material specially designed to uphold overhangs and complicated geometries. It is easily removed by hand or water.

Materials

Vero

High resolution 3D printing material for visual models. Great for checking for fit and accuracy.

VeroClear

Perfect for light pipes and prototypes that need optical transparency.

ABS-Like

Great for simulating ABS plastics with higher temperature resistance and toughness.

Rubber-Like

Great for simulating overmolds and rubbers with different durometers (hardness).

Cost Saving Tip

Limit the amount of support material necessary, as this drives up the cost due to the amount of extra material used + cleaning time.

+ Design for Manufacturing Tips

- Gaps for mating parts: 0.1mm off of each wall
- Avoid sharp corners at
- Avoid enclosed designs. To remove support material from PolyJet parts, the machinist must have line-of-sight access to all areas that require cleaning.
- Ribbing helps avoid warping on long, flat parts
