3D Digital Printing - Plastic Prototypes
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 creates a 3D part.

Prototypes can be printed in over 360,000 colors. The new Stratasys J750 can mix five different color materials (cyan, magenta, yellow, black, & 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") for fine delicate features. The Stratasys J750 also has great repeatability, so if you need copies of full color models you can be assured they will look the same. In the past, we would have 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.

Materials can be different durometers from soft flexible rubber-like to rigid. Our polyjet printers can make a rigid part with a soft overmold. Materials can range from clear to opaque. Parts can be created to withstand repeated bending and flexingThe system is ideal for designers and engineers looking to effectively demonstrate the varying material components in complex or assembled products.

The polyjet printing enables you to simulate diverse mechanical and physical properties. Base materials can be mixed to make materials that range from rubber to rigid; opaque to transparent; black to white. Base materials include: flexible TangoPlus to vary translucency and flexibility, flexible TangoBlack to vary shade and flexibility, and VeroClear to vary color intensity and translucency.

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 material can be used for advanced functional testing, hot air and water flow, static applications and exhibition modeling.

Midwest Composite has two polyjet printers.
