Carbon's current-generation Digital Light Synthesis (DLS) production printers for polymer parts. The M3 Max features a true 4K light engine with double the build area of the M3. Both use closed-loop force and temperature control to reduce variation across a single build by up to 50%, enabling consistent production of footwear midsoles, automotive brackets, and medical devices at volume.
Carbon's large-format production printer with a 400 x 250 x 460 mm build volume, designed for high-volume runs of large polymer parts. Used by Adidas for mass production of Futurecraft midsoles. Operates on subscription with accompanying resins and process expertise, enabling true additive manufacturing at industrial scale without injection molding tooling.
A generative design and automated orientation software suite that optimizes part geometry for DLS printing. Analyzes functional requirements and automatically generates lattice structures and support strategies. In 2025, Carbon expanded the AO Suite with new features for dental and industrial parts showcased at IDS 2025.
