About the Process

PolyJet is a 3D printing technology. It's 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.

The most advanced PolyJet systems, Objet Connex 3D Printers, combine diverse 3D printing materials in one model by jetting multiple materials simultaneously. This means the user can selectively position multiple materials in one printed prototype and even combine two or three materials to create composite models with distinct, predictable properties.

Machines

Capable of impressive detail and multi-material printing, PolyJet printers are some of the most expensive printers in the world, with even rudimentary machines costing tens or hundreds of thousands of USD.

At Fictiv, we accept only the top models of Polyjet machines on our platform for reliability and accuracy. Below is a snapshot of some of the machines on the Fictiv network:

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
