We use two major types of rapid prototyping methods at Omnica. Both have their advantages when producing working prototypes or demonstration models.
- Subtractive – We fabricate metal or plastic parts and components by removing material with our manual and CNC machine tools.
- Additive – We use our 3D printers to create plastic parts and components by building in layers from CAD models.
Machining (subtractive rapid prototyping)- Machine tools are a necessity for a company who develops complex, high-tolerance products. The ability to mill metal and plastics is important enough that we have two full-time machinists and an in-house CAD/CAM specialist (for programming MasterCAM™). We can either fabricate production-quality parts outright, or mill an aluminum mold to be used with our Arburg injection molding machine. Both methods allow us to build parts from production-spec polymers or with materials to be used in the final product.
3D Printing (additive rapid prototyping)- We have five 3D printers that can quickly produce Polymer-Jet (right) or FDM (fusion Deposition Modeling – below) parts made from either UV-cured polymers or production-grade thermoplastics like ABS. The items these "additive manufacturing" methods produce work well as accurate patterns for our urethane molding shop, "one- off" models, and in some cases, robust components or low volume articles for fit and testing purposes.
We can trim days from a project timeline.
When Omnica was founded in 1984, we had a lathe and a Bridgeport milling machine. As you can see from our in-house equipment list, we now have the sophisticated tools and capabilities to perform all but the most esoteric milling, metal shaping, and plastics fabrication operations.
