Abstract
The present disclosure various apparatuses, and systems for 3D printing. The present disclosure provides three-dimensional (3D) printing methods, apparatuses, software and systems for a step and repeat energy irradiation process; controlling material characteristics and/or deformation of the 3D object; reducing deformation in a printed 3D object; and planarizing a material bed.
Claims23
A method for printing a three-dimensional object, comprising:
- (a) providing a material bed comprising a pre-transformed material, wherein the pre-transformed material comprises a solid, a semi-solid, or a liquid material, wherein the material bed comprises an exposed surface;
- (b) planarizing the exposed surface by directing an excess of the pre-transformed material from the exposed surface disposed above a plane into an internal compartment of a material remover through a nozzle of the material remover, to form a planarized exposed surface, wherein the nozzle comprises an adjustable volume;
- and
- (c) using an energy beam to transform the pre-transformed material in at least a portion of the planarized exposed surface to a transformed material, wherein the transformed material is at least a portion of the three-dimensional object.
