Abstract: The present disclosure provides systems and methods for printing three-dimensional (3D) objects. A system for printing a 3D object may comprise at least one platform configured to hold a film of at least one mixture, a deposition unit for providing the film of the at least one mixture, and a building unit for forming at least a portion of the 3D object from the film of the at least one mixture. The system may further comprise a controller operatively coupled to the at least one platform. The controller may be configured to direct the at least one platform to move from the deposition unit to the building unit, or vice versa, along a plurality of non-overlapping paths.

Abstract: Methods, systems, and apparatus, including a method of multi-material stereolithographic three dimensional printing comprising, depositing a first material through a first material dispenser of a stereolithographic three dimensional printer onto an optical exposure window to form a first material layer; curing the first material layer to form a first material structure on a build head of the stereolithographic three dimensional printer; depositing a second material through the first material dispenser or a second material dispenser onto the optical exposure window to form a second material layer; and curing the second material layer to form a second material structure on the build head.

Abstract: Methods, systems, and apparatus, including medium-encoded computer program products, for improving 3D printing systems and techniques include, in one aspect, a system including: three dimensional (3D) printer hardware; and at least one computer communicatively coupled with the 3D printer hardware, the at least one computer programed to receive 3D print type inputs for an object to be 3D printed and create a 3D print profile including parameters for 3D printing the object using the 3D printer hardware by matching the 3D print type inputs against a database.

Abstract: Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium, including a system for reducing adhesion during cure processing for a stereolithographic 3D printed object. The system includes resin tank for maintaining a liquid photopolymer resin. The system further includes a light source. The system further includes controller for selectively exposing the liquid photopolymer resin to form a solid object in the resin tank. The resin tank is constructed of a rigid material that has an oxygen permeability that is above a first threshold so as to reduce a separation force required to remove the solid object from the resin tank after curing.
