US 2022/0032539 A1 · STEREOLITHOGRAPHY DEVICE COMPRISING CARTRIDGE DEVICE

Abstract

In a stereolithography device (1), a three-dimensional object (2) is generated by curing a photosensitive substance (3) under the action of specific radiation, wherein the device includes a support unit, a radiation source (8) for generating the radiation, and a cartridge unit (10) that can be positioned on the support unit and removed therefrom. The cartridge unit (10) includes an interior space (140) surrounded by a casing (14), wherein the casing of the cartridge unit is deformable and at least partially transparent to the radiation triggering the curing process. The interior space (140) surrounded by the casing has a volume including a receiving space (4) in which the photosensitive substance (3) is present for at least a duration of an irradiation and curing process and accessible to the radiation.
