Overview of Technique
This technique is considered high resolution in contrast to FDM. A monomer ink turns into a solid while exposed to UV light (360-405 nm, depending on the printer). The specific pixel exposure to UV light can be achieved using a LASER beam or DLP projector, in order to form the structure layer-be-layer as thin as 50 μm. Since the ink is placed in a bath, the printed materials can easily be replaced to other type of acrylate-based inks with different properties and colors.
