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.
A method for forming three-dimensional objects by photo-curing a photo-curing liquid polymer exposed to a radiation, wherein said three-dimensional objects form by growth, due to the progressive curing of said photo-curing liquid polymer, in a space between a base transparent to the radiation and a supporting plate, said supporting plate progressively moving away from said transparent base, characterized in that said motion of said supporting plate is tilting, swinging, rotating, and/or swirling in three-dimensional space.
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 having a hole therein covered by a material transparent to said radiation, and a supporting plate configured to move away from the base of the tank, characterized in that said motion of said supporting plate is tilting, swinging, rotating, and/or swirling in three-dimensional space.
