3D Printing Process Overview: Carbon DLS®

What Is Carbon DLS? How Does It Work?

Carbon Digital Light Synthesis® (Carbon DLS®) is a 3D printing technology that uses digital light projection, oxygen-permeable optics, and programmable liquid resins to produce products with end-use durability, resolution, and surface finish. Unlike other methods it employs a unique process called Continuous Liquid Interface Production (CLIP) to create parts.

The process begins with a pool of liquid resin. A UV light projector shines patterns through an oxygen-permeable window onto the resin, solidifying it layer by layer. Unlike conventional layer-by-layer methods, CLIP maintains a consistent flow of liquid resin beneath the curing zone, enabling a continuous and seamless build process. This gives the parts isotropic properties, meaning that strength is even regardless of orientation.

After printing, parts undergo a thermal curing step to enhance their strength, durability, and thermal stability, resulting in production-ready components.

Advantages Complex part geometries can be achieved Excellent mechanical properties for demanding applications compared to SLA and Polyjet Food grade and biocompatible materials available Smooth surface finish Ideal for small parts or lattice structures Offers flexible 3D printing resins, including SIL 30, EPU 40, and FPU 50.

Disadvantages Limited material selection Need of support structures for overhanging features Higher cost compared to some other 3D printing processes. Thick walls (above 2.54 mm / 0.1″) may cause shrinkage and warpage Limited maximum part size with a typical build envelope of 187 mm × 116 mm × 325 mm.
