DLS

The partnership between GKN Additive (Forecast 3D) and 3D-printing technology company Carbon equals greater
capabilities for the automotive market as well as adding value for prototyping.

Carbon Digital Light Synthesis™ (DLS) is a rapid 3D-printing process that uses digital light projection, oxygen-permeable
optics, and programmable liquid resins to produce high-performance robust parts comparable to traditional manufacturing
plastics. This process accelerates high-value product development cycles while using the same platform specifically designed
to provide a cost effective path from prototyping to high-volume production.

BENEFITS

  • Isotropic parts with exceptional surface finish
  • Best-in-class material performance
  • Highly precise fine features
  • Excellent accuracy and repeatability
  • Technology built for rapid scaling from prototype to
    production

APPLICATIONS

  • Automotive interior and exterior parts
  • Electrical connectors
  • Parts that require flame-retardant material
  • Tough, durable industrial applications

MATERIALS

EPX 82. A high-strength epoxy-based engineering material with excellent long-term durability and mechanical properties, comparable to lightly glass-filled thermoplastics.

EPX 86FR. A flame-retardant resin with an unmatched combination of functional toughness, high strength, and long-term stability.

RPU 70. This rigid polyurethane – comparable to acrylonitrile butadiene styrene (ABS) – is a good choice for parts that require strength, toughness, and moderate heat resistance.

RPU 130. A strong, tough, and heat resistant resin with a unique combination of performance attributes, making it comparable to an unfilled thermoplastic such as nylon and polypropylene.

EPU 40. This high-performance polyurethane elastomer is a good choice for applications where high elasticity and tear resistance are needed.
