Unlike FDM technology, UV LCD 3D printer utilizes the principle of light curing to make the photopolymer resin solid, achieving an unprecedented level of detail. uv led printing has great application in Jewelry, Action figures, Art models, Collectors’ items, Medical and so on. There is a matrix LED array at the bottom as the light source in combination with a high-resolution LCD photomask to shape the light image and cure thin layers of resin in the print bed. And through the layer-by-layer curing, the final product is produced. The LCD photomask is digitally displayed and it is composed of square pixels, the higher resolution unit the finest accuracy.
