Carbon DLS

Carbon DLS (digital light synthesis) is an industrial 3D printing process that creates functional, end-use parts with mechanically isotropic properties and smooth surface finishes. You can choose from both rigid and flexible polyurethane materials to meet your application needs for high impact-resistance components.

How Does Carbon DLS Work?

Carbon DLS uses CLIP (continuous liquid interface production) technology to produce parts through a photochemical process that balances light and oxygen. It works by projecting light through an oxygen-permeable window into a reservoir of UV-curable resin. As a sequence of UV images are projected, the part solidifies, and the build platform rises.

At the core of the CLIP process is a thin, liquid interface of uncured resin between the window and the printing part. Light passes through that area, curing the resin above it to form a solid part. Resin flows beneath the curing part as the print progresses, maintaining the continuous liquid interface that powers CLIP. Following the build, the 3D-printed part is baked in a forced-circulation oven where heat sets off a secondary chemical reaction that causes the materials to adapt and strengthen.
