These micro-mirrors correspond to each pixel of the image, and the building time of the object is minimized. DLP has moving micro-mirrors to control light reflection. DLP uses high power LEDs and photosensitive resin materials to build layers. Then, the nozzle extrudes melted filament onto the build plate of a print chamber, creating a 3D printed model. After accessing the feeding system, the material gets guided to the extruder where it is then melted. FDM comprises an extruder, a nozzle, a print chamber, and a filament feeding system. It uses materials extruded from nozzles, or a photopolymer jetted over the workspace and then the object is polymerized with a UV light source. Smooth and fine surface details and high accuracy are the advantages of SLA. SLA uses an ultraviolet laser to polymerize photosensitive resin liquid into the desired shape. The common techniques that use light to polymerize resin are stereolithography (SLA), polyjet or material jet (MJ), digital light processing (DLP), and continuous liquid interface production (CLIPTM ). 3D printing allows the production of complex objects, shortens manufacturing time, and reduces material costs. Additive manufacturing (AM) is also known as Rapid Prototyping (RP) or 3D printing, and it is a process in which objects are built layer by layer. CAD/CAM systems have been widely used in dentistry and definitive casts can be fabricated using subtractive or additive technology.
