Abstract
There are 7 categories for the additive manufacturing (AM) technologies and a wide variety of materials that can be used to build a computer aided designed (CAD) 3-Dimensional (3D) object. The present article reviews the main AM processes for polymers for dental applications: stereolithography (SLA), direct light processing (DLP), material jetting (MJ) and material extrusion (ME). The manufacturing process, accuracy and precision of these methods will be reviewed, as well as, their prosthodontic applications. Keywords: 3D printing; Additive manufacturing technologies; Direct light processing; Fused deposition modelling; Material extrusion; Material jetting; Multijet printing; Prosthodontics; Stereolitography.
Highlights
C omputer aided manufacturing technologies (CAM) are based on milling or additive manufacturing (AM) where in the latter an object is fabricated through layer-by-layer building process [1]
In the fused deposition modelling (FDM) technologies, the 3D printer extrudes a melting plastic filament that has been heated just beyond its melting point and is deposited one layer at a time onto a building platform according to the 3D data supplied to the printer
The production of the pattern started with CAM processing and followed by model fabrication and post processing the 3D object, which is specific to the technology and the printer used
