Abstract: System and methods for three-dimensional printing are provided. In accordance with one aspect, a method for multimaterial fabrication of three-dimensional (3D) printed structures includes lifting a printing platform having a 3D printed structure formed thereon to remove the 3D printed structure from a plate through which radiation was transmitted to fabricate the 3D printed structure and activating a blast of an air jet focused on the surface of the plate under the printing platform to remove waste material left on the surface of the plate when the printing platform is lifted. In accordance with another aspect, method for three-dimensional (3D) printing includes photopolymerizing a photocurable resin to form a fabricated structure and programmed thermal treating of the fabricated structure for transesterification of material of the fabricated structure.
