What is Carbon Digital Light Synthesis ?

Carbon DLS technology, using the digital light synthesis (DLS) processes, is best used for small to medium-sized prototypes and end-use production parts. Carbon DLS is a new additive manufacturing technology that 3D prints parts using digital light projection (DLP) with engineering-grade materials to provide injection molded like parts with a similar finish, strength, and material properties.

Carbon stands out due to the wide range of material offerings. Here are some of the most popular materials for production applications:

    • EPU 40 and 41 are similar to a 70 shore A TPU with either energy damping or energy return characteristics.
    • EPX 82 is used for high strength, rigidity and durability are needed.
    • RPU 70 is the most commonly used material because it mimics a production ABS material.


  • UMA 90
  • CE 221
  • EPU 40/41
  • EPX 82
  • FPU 50
  • IND 405, Clear
  • MPU 100
  • RPU 70
  • RPU 130
  • SIL 30
