1. A cartridge for printing a three-dimensional (3D) object, comprising:
a single-use or disposable enclosure adapted to be aligned with a curing light engine external to the cartridge, the enclosure housing a channel, a first chamber, and a second chamber, wherein:
the channel connects a side wall of the first chamber with a side wall of the second chamber to fluidly communicate the first chamber with the second chamber,
the first chamber is adapted to sealably store a printing material, and
the second chamber is adapted to receive a platform; and
a piston, movable within the first chamber adapted to hydraulically move the platform and transfer a portion of the printing material from the first chamber to a printing area between a surface of a window and the platform in the second chamber for receiving a curing light from the curing light engine for curing a layer of the printing material onto the platform or onto a cured layer of the printing material on the platform, in order to build the 3D object on the platform.
