METHOD OF OPERATING STEREOLITHOGRAPHIC DEVICE TO PREVENT STICKING OF 3D OBJECT TO CONTAINER USING VIBRATIONAL EXCITATIONS Russian patent published in 2023 - IPC B29C64/255 

FIELD: stereolithographic devices.

SUBSTANCE: invention is related to a method for operating a stereolithographic device for creating a three-dimensional object from a photocurable substance. The stereolithographic device contains: a container; a platform; an optical block; and an oscillating block. The method includes the stages of storing the photocurable substance in the container; supporting the three-dimensional object using a platform that is movable relative to the container; sequentially projecting multi-layer images onto the photocurable substance using the optical unit in order to cure the photocurable substance deposited between the three-dimensional object and the bottom of the container. The method additionally includes the stage of horizontal oscillations of the container using an oscillating unit simultaneously with the projection of multilayer images. The horizontal oscillation of the container is produced with an amplitude that is smaller than the pixel size of the multi-layer images.

EFFECT: preventing the three-dimensional object from sticking to the bottom of the container and reucing the blurring of the three-dimensional object.
