LCD/DLP Small 3D Printers

One of the latest developments in resin 3D-printing is MSLA, also called LCD based 3D-printing. This technique uses an affordable LCD screen to create the mask, eliminating expensive DMD chips that are used in DLP techniques. This technique works by an array of LED’s illuminating on the LCD. The LCD is used as a mask, which creates the curing pattern. The liquid resin turns into a rigid plastic on the spots where the light ‘hits’ the resin.

DLP was originally a kind of projection technology. Later, the light-curing 3D printer using this projector was also called a DLP 3D printer.
DLP light curing forming can form one surface at one time, and the forming speed is fast. With high-resolution projectors and good forming quality resin, the 3D printed products have very high precision.
This kind of forming technology first uses slicing software to cut the model, and the projector plays the slide. The image of each layer is photopolymerized and cured in a thin area of the resin layer to form a thin layer of the part, and then the forming table moves one layer. The projector continues to play the next slide, continues to process the next layer, and so on, finally forming a finished model. It is often used in fields such as jewelry and dentistry.
