Abstract: A digital light processing system applied in a three-dimensional printing system includes a container set containing solidifiable material. A platform set in contact with a portion of the solidifiable material is included, together with a projector emitting a primary electromagnetic radiation. One or more optical component sets are between the projector and the platform. An optical component set can convert the primary electromagnetic radiation into a plurality of secondary electromagnetic radiations, and any of the plurality of secondary electromagnetic radiations can be projected on the solidifiable material contacting the platform set, to form a solid layer. A digital light processing procedure in a three-dimensional printing method is also disclosed.

Abstract: A digital light processing (DLP) three-dimensional (3D) printing system includes a container containing a solidifiable material; a platform contacting a portion of the solidifiable material; a projector projecting an electromagnetic radiation on the solidifiable material to form a solidified layer; and an optical component between the projector and the platform; wherein the optical component is rotated to shift the electromagnetic radiation during the formation the solidified layer, thus forming a rounded edge and an enlarged area of the solidified layer. A digital light processing (DLP) three-dimensional (3D) printing method is also disclosed.
