Zusammenfassung:	Systems, apparatus, and methods are described for additive manufacturing or three dimensional (3D) printing of objects using a set of physical masks and a flexible base vessel. An additive manufacturing device can include a light source configured to emit light; a vessel including: a receptacle configured to contain a volume of print material; and a transparent base through which light can be received to cure a portion of the volume of print material, which is not taut prior to photopolymer installation; a set of masks defining a set of patterns; and a mask carrier configured to support the set of masks between the light source and the transparent base to control a pattern of the light that is received through the transparent base, the mask carrier movable along the transparent base to cure portions of the volume of print material to form a layer of an object while releasing cured portions from the flexible base via a combination of forces.
