Conventional 3D printed materials often exhibit variable strength and mechanical properties depending on the direction in which they were printed. DLS 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.
CLIP is a photochemical process that carefully balances light and oxygen to rapidly produce parts. 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.
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. Resin flows beneath the curing part as the print progresses, maintaining the “continuous liquid interface” that powers CLIP.
Once a part is printed with CLIP, it’s baked in a forced-circulation oven. Heat sets off a secondary chemical reaction that causes the materials to adapt and strengthen.
