Abstract
Methods and apparatus for forming three-dimensional objects by photo-curing a photo-curing liquid polymer exposed to a radiation in a space between a base transparent to the radiation and a supporting plate. The supporting plate moves progressively, in some cases continuously, away from said transparent base during the printing process, and that movement is characterized in that it is tilting, swinging, rotating, and/or swirling in three-dimensional space, based on the print geometry, in order to expedite printing speed and resin propagation throughout the build area. In one embodiment, the movement may resemble a spiral or helical path from the standpoint of points around its circumference.
Claims5
An apparatus for forming three-dimensional objects by photo-curing a photo-curing liquid polymer through exposure to a radiation, said apparatus including a tank for collecting said photo-curing liquid polymer, a base of the tank being transparent to said radiation, a supporting plate configured to support an object being formed, and a controller that includes a processor and memory, the memory storing instructions that when executed by the processor, cause the supporting plate to continuously move away in a helical manner from said transparent base during photo-curing of said photo-curing liquid polymer.
