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.
Claims29
A method for forming a three-dimensional object, comprising:
- (a) altering a three-dimensional model of a requested three-dimensional object to form an altered model, which altering comprises a structural alteration, wherein at least a first derivative of the difference between (i) the altered model and (ii) the three-dimensional model of the requested three-dimensional object, is continuous;
- and
- (b) transforming at least a portion of a material bed with an energy beam according to the altered model, wherein the three-dimensional object is substantially similar to the requested three-dimensional object.
