Carbon M2 3D Printer

The Carbon M2 3D printer uses continuous liquid interface production technology (CLIP) to rapidly create physical objects from 3D models. Carbon's tunable photochemical process involves controlling the oxygen flux through a light- and oxygen-permeable window, which creates a thin (10’s of micrometers thick) region within the resin pool where oxygen inhibits photopolymerization. As cross-sectional images of the 3D model are projected into the resin pool from below, the physical object continuously materializes from just above this thin oxygen-rich region. This technology produces “layerless” components with smooth external surfaces and solid cross-sectional areas of printed features. Components created with the Carbon M2 are printed roughly 25 to 100 times faster than traditional SLA printing and have more consistent mechanical properties.
