Watch our video on PolyJet 3D Printing:
Xometry offers PolyJet rigid photopolymer (PJ3D), which is a 3D printing technology that builds parts out of a UV-curable resin with high detail and the ability to apply different material properties. PJ3D works similar to an inkjet printer, where thousands of micro-dots of material are deposited and cured, layer by layer, to build a part from the bottom to the top.
This process is best for concept models, test-fitting parts, or creating multi-material parts that simulate the feel of the eventual end-use part, such as applying a rubbery overmolded feature over a rigid one. The ability to have both rigid and rubber-like features on one print via multi-material printing is one of the most overlooked advantages of PolyJet technology.
At Xometry, our PolyJet machines also support full-color prints, rendering hundreds of thousands of colors and textures in a single print. Simply upload a compatible CAD file with color information (we recommend .3MF) and select Multi-Color, CAD-Defined from the material drop-down.
Tolerances and Limitations
Here are the basic tolerances and limitations of PolyJet:
- +/- 0.004” for the first inch is typical, plus +/- 0.002” for every inch thereafter.
- Build area up to 19 x 15 x 7"
- Rubber-like materials approximate shore A values and may vary between geometries.
- PJ3D prints in 0.0012" layers (30 μm), making it a very detailed and accurate process.
If you plan on painting your PolyJet part, it is recommended to go over it thoroughly with a wet abrasive pad to remove remnants of its gel-like support material. If your part requires more mechanical strength or high durability, you may want to consider other processes like SLS, FDM, or SLA.
