Prototyping of Plastic and Metal Parts

Dielectric Manufacturing helps manufacturers design and build better products through our prototyping service. Prototyping is an excellent way to test a component before investing in full-scale production. With our prototyping services, you can test multiple versions of your design before manufacturing for optimal results.

Our customers rely on our extensive design experience and our expertise in plastic and metal materials to collaborate in the design of parts and components for their manufacturing or assembly processes.

That includes prototyping of new products and enhancements to existing products.

Dielectric Manufacturing offers a complete range of prototyping capabilities:

  • Stereolithography (SLA) – produces parts one layer at a time with an ultraviolet laser that traces a cross-section of the pattern on the surface of a liquid resin. This cures and solidifies the pattern and joins it to the layer below.
  • Selective Laser Sintering (SLS) prototypes – for lightweight yet complex and highly detailed prototypes and end-use parts(which can include living hinges).
  • Fused Deposition Modeling (FDM) prototypes – for accurate, consistent models and end-use parts from a wide variety of production-grade thermoplastics.
  • Cast Urethane prototypes – for highly accurate, geometrically complex models and end-use parts.
  • Computer Numeric Controlled (CNC) prototypes – for models and end-use parts made from a wide selection of materials with optional value-added operations.

We also offer short-run manufacturing in conjunction with prototyping and as a stand-alone service.
