A polyjet printer works like an inkjet printer, but instead of ink it deposits liquid photopolymer, which is then cured with UV light. By building up layers, the Objet, a polyjet professional 3D printer, creates a 3D part. The properties can be adjusted via digital combinations of materials. Polyjet printing enables the simulation of diverse mechanical and physical properties. Base materials can be mixed to make materials that range from rubber to rigid, opaque to transparent, and black to white.

Our polyjet printers can make a rigid part with a soft over-mold. The parts can be created to withstand repeated bending and flexing. The system is ideal for designers and engineers looking to use 3D prototyping to effectively demonstrate the varying material components in complex or assembled products.

The new Stratasys J750 can mix five different color materials (cyan, magenta, yellow, black, and white) to make a full spectrum of color, similar to the way a 2D printer works. The Stratasys J750 can also print color gradients, transparent and translucent materials, and materials of different durometers. In addition to all its material and color capabilities, the Stratasys J750 can print layers as thin as 14 microns (.00055 inch) for fine, delicate features. The Stratasys J750 also has great repeatability, so if you need copies of full-color models, you can be assured that they will be identical. In the past, we would have had to make different parts or use complicated masks and paint to make a complicated color model. Now, we can make the model in one printing operation.

We can also make parts with simulated ABS. Digital ABS simulates ABS-grade engineering plastics by combining high-temperature resistances with high toughness (RGD5160-DM fabricated from RGD515 and RGD535). High-temperature materials can be used for advanced functional testing, hot air and water flow, static applications, and exhibition modeling.
