Abstract
Sintering methods comprising (a) providing a layer of powder material on a platform; (b) projecting incident light from a source onto a surface area of the layer of powder material, wherein the incident light is projected for a sufficient time to densify the layer of powder material and form a layer of densified material; (c) optionally cooling the layer of densified material to a sufficient temperature to solidify or vitrify the layer of densified material to form a layer of sintered material; and (d) repeating steps (a) to (c) to form a sintered article in a layer-wise fashion are disclosed. The incident light may cause complete melting of the powder material or heat the powder material above its glass transition temperature. In general, the incident light is projected simultaneously and for a time span substantially the same as formation of the layer of densified material.
