It is a process that builds 3-D objects by converting liquid materials into solid parts by curing them using a light source, which causes chains of molecules to link, forming polymers. The process is used for creating models, prototypes, patterns, and production parts. A typical method uses a UV laser to create cross-sections of the object within a vat of liquid photopolymer. The process was first developed in 1986. The process is valued to create accurate parts with repeatable dimensions; applications include engineering assemblies, jewelry casting, and dental repairs. ]]></dc:description></metadata>
