Continuous Liquid Interface Production begins with a pool of liquid photopolymer resin, part of the pool bottom is transparent and the resin solidifies by ultraviolet light which has a wavelength from 10.
The continuous process begins with a pool of liquid photopolymer resin. Part of the pool bottom is transparent to ultraviolet light (the "window"). The light causes the resin to solidify. Ultraviolet (UV) is a form of electromagnetic radiation with wavelength from 10 (with a corresponding frequency around 30 PHz) to 400 nm (750 THz), shorter than that of visible light, but longer than X-rays.
