LCD 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.
