Digital Light Synthesis™
Digital Light Synthesis is a breakthrough technology that uses digital light projection, oxygen permeable optics, and programmable liquid resins to produce parts with exceptional mechanical properties, resolution, and surface finish. Carbon DLS™ technology allows engineers and designers to iterate faster, deliver projects with less risk, and radically reimagine their products by introducing consolidated parts, impossible geometries, and programmable lattices.
Digital Light Synthesis technology is driven by Carbon’s groundbreaking Continuous Liquid Interface Production™, or CLIP™, and programmable liquid resins. CLIP uses digital light projection in combination with oxygen permeable optics, and was described in a groundbreaking article in the journal Science.
Traditional resin-based 3D printing processes produce weak, brittle parts. Carbon overcomes this by embedding a second heat-activated programmable chemistry in our materials. This produces high-resolution parts with engineering-grade mechanical properties.
The Dead Zone
The heart of the CLIP process is the “dead zone” — a thin, liquid interface of uncured resin between the window and the printing part. Light passes through the dead zone, curing the resin above it to form a solid part without curing the part onto the window. Resin flows beneath the curing part as the print progresses, maintaining the “continuous liquid interface” that powers CLIP and avoiding the slow and forceful peeling process that is inherent to many other resin-based printers.
Heat Sets the Mechanical Properties
Once a part is printed on a Carbon printer, it’s baked in an oven. Heat sets off a secondary chemical reaction that causes the materials to adapt and strengthen, taking on exceptionally strong characteristics.
Isotropic Parts With Exceptional Surface Finish
Conventional 3D printed materials often exhibit variable strength and mechanical properties depending on the direction in which they were printed. Digital Light Synthesis parts behave consistently in all directions. The resolution and gentleness of our process — where parts aren’t harshly repositioned with every slice — make it possible to exploit a range of materials that have surface finish and detail needed for end–use parts.
Traditional 3D Printing
3D printed parts are notoriously inconsistent. Their mechanical properties vary depending on the direction the parts were printed due to the layer-by-layer approach.
Digital Light Synthesis
Digital Light Synthesis produces consistent and predictable isotropic mechanical properties, creating parts that are solid on the inside like injection molded parts.
Product Design, Perfected
Digital manufacturing sends modern design soaring, giving designers and engineers the freedom to bring their most inspired ideas to life without the constraints of molding or machining.
