A group of researchers from the University of California, Los Angeles (UCLA) are working on using an SLA 3D printing method to manufacture temporary teeth restorations. Temperature Controlled Mask image projection-based stereolithography (TCMIP-SL) processes use a set of horizontal planes to slice a 3D object, and each slice is converted into a 2D mask image. Then, a 2D patterned light beam, which is controlled by a digital micromirror device (DMD), is projected on the surface of a photocurable material, which is then cured layer by layer to build the 3D object.
