The brief

Analyst view
  • Founded December 2013 by Joseph DeSimone and others; Sequoia Capital was the first major investor.
  • M3 and M3 Max released January 2022 with 4K light engines and improved throughput and surface finish.
  • November 2025: Carbon raised $60M to scale large-format platform with support from Sequoia, Silver Lake, adidas.

Technical approach

As reported
Digital Light Synthesis

Continuous liquid interface production

DLS uses a programmable light engine to polymerize photopolymer resin continuously, not layer-by-layer. This produces smooth surfaces and faster print times.

Hardware lineup

M-series and L1 printers for different scales

M2 for prototyping, M3/M3 Max with 4K light engines for speed and resolution, L1 for serial production.

Materials library

Rigids, elastomers, dental materials

Proprietary resins optimized for different end-use: rigid parts, flexible elastomers, and dental formulations.
