A machine reads data generated from a CAD drawing and lays down successive layers of liquid, powder or sheet material and builds up the model from a series of cross sections. These layers, which correspond to the virtual cross section from the CAD model are joined together or fused to create a final shape.
The advantage of this process is the ability to create almost any shape or geometric feature.
Polyjet 3D printing
This is a 3D printing process that allows precision with layers up to seven times finer than standard stereo lithography models.
Prototypes can be built from seven different resins making our 3D printer extremely versatile. The fine layer resolution and the material options make the process well-suited for building a variety of shapes, small figurines, rubber-like parts and injection molded-like models.
- Produces ultra fine details with .0006 inch (16 microns) horizontal layers.
- Currently able to print six different resins, including flexible, Shore A materials.
In the RTV (Room Temperature Vulcanized) tooling process, liquid silicone rubber is poured around a master pattern. The resulting mold is pulled from the pattern and cured, then subsequently used to cast urethane parts. The key advantage of this process is being able to obtain higher quantities of prototypes at a relatively low cost.
- Functional prototypes and models with excellent surface finish and detail
- Multiple urethanes offering multiple temperature tolerances, as well as color and texture
- Extremely accurate
- Low run production
Post Process Model Finishing
MPI Restoration Services offers detailing to improve the aesthetic properties through machining, sanding, filling, dying and painting.
This is the automatic construction of physical objects using additive manufacturing technology. Virtual designs are created using computer aided design (CAD) software which transforms thin, virtual, horizontal cross-sections of the object so that an identical model is created.
