Who We Are

Carbon® provides industry-leading digital manufacturing solutions that empower companies to create revolutionary products anywhere and at any scale. Carbon joins advanced hardware, software, and polymer materials capabilities on one digital manufacturing platform – giving companies the ability to design and bring better products to market in less time.

Light and Oxygen

In 2015, we unveiled the scientific breakthrough behind the Carbon Digital Light Synthesis (Carbon DLS) process, a rapid 3D printing technology that controls light and oxygen to produce end-use parts directly from a pool of resin. Now, with the broadest range of engineering-grade materials in the industry, Carbon makes it possible to design, rapidly optimize, and digitally manufacture isotropic parts with the Carbon DLS process to meet your specific product performance needs. Across a range of industries, Carbon has enabled leading companies, including adidas, Riddell, Ford, and Beckton Dickinson to create and produce products that have set new standards for design, performance, and speed to market.

Carbon has customers in 17 countries and is continuing to expand globally.
