Abstract
The present disclosure provides three-dimensional (3D) printing methods, apparatuses, systems, and non-transitory computer-readable medium. The disclosure delineates real time manipulation of three-dimensional printing to reduce deformation. The present disclosure further provides 3D object formed using the methods, apparatuses, and systems.
Claims30
A method for forming a three-dimensional object, comprising:
- (a) transforming at least a portion of a material bed with an energy beam, wherein the material bed is disposed in an enclosure;
- (b) while transforming the at least the portion of the material bed, cooling the material bed with a first cooling member that is mobile, wherein the first cooling member is disposed in the enclosure, wherein the first cooling member is separated from an exposed surface of the material bed by a gap comprising a gas, wherein the first cooling member comprises a heat conductive material;
- and
- (c) cooling the first cooling member with a second cooling member that is disposed (i) at a wall of the enclosure, or (ii) outside of the enclosure, wherein the second cooling member is stationary, wherein the second cooling member comprises a first opening.
