Why Choose Carbon DLS for 3D Printing

Carbon DLS (digital light synthesis) Is an industrial 3D printing process that produces functional, end-use parts with mechanically isotropic properties and smooth surface finishes. It offers a range of rigid and flexible polyurethane materials designed for high-impact resistance and durability to meet your needs.

Key Advantages and Uses:

  • Ideal for complex designs that are difficult to mould
  • Provides isotropic mechanical properties and smooth surface finishes
  • Produces parts in materials similar to ABS or polycarbonate
  • Suitable for durable, end-use 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.
