Additive Manufacturing - Self-Lubricant Sublayer Photocuring (LSPc) technology:

​Founded by industrial engineers, Nexa3D has developed and patented the self-Lubricant Sublayer Photocuring (LSPc) technology, cutting down the printing time to 1 minute per centimetre while achieving highest precision. The technology seems to work similar to Continuous Liquid Interface Production (CLIP) technology -this technology was explained beforehand-, creating objects in a continuous process without layers.

Unlike conventional bottom-up 3D printing systems, LSPc interposes a transparent self-lubricating film between the bottom of the tank, the photo-curing resin and the light source. By gradually releasing a layer of oil, this enables the finished resin to solidify while suspended on the substrate. This sublayer of oil prevents newly formed layers from sticking to the build platform and eliminates the need for extraction systems used in conventional technologies.
