FIELD: stereolithography devices.
SUBSTANCE: invention is related to a stereolithography device for generating a three-dimensional object. The device contains an optical unit for projecting an image onto a photocurable substance for curing the photocurable substance deposited in the focal layer; and a control block. The device further includes a detection unit, which includes detection means movably positioned in the detection portion for detection during generation or during a pause in generation of an image projected by the optical unit, and for outputting a detection signal. The device includes a first drive means for moving the detection means into or out of the detection area. The optical block includes a second drive means coupled to the optical block for moving the focal layer into or out of the detection region. The control unit adjusts the optical unit and/or changes the image to be projected based on a signal indicating the detected image.
EFFECT: invention provides a stereolithography device that can selectively perform optical adjustment and modification of an image during generation or during a pause in generation in a universal, extensive and flexible manner.
