Abstract
The invention is a system and method for printing 3D objects. The method may include providing a disposable cartridge including a build chamber coupled to a storage chamber adapted to hold a build material; seesawing a piston and a platform within the storage chamber and the build chamber, respectively, to transfer the build material between the storage chamber and the build chamber via a feeding path; and curing a layer of the build material onto the platform or onto a cured layer of the build material on the platform until the 3D object is formed. The system may include the cartridge; a movement module coupled to the piston and the platform of the cartridge; and a controller configured to drive the movement module to seesaw the piston and the platform to hydraulically transfer a portion of the printing material to a printing area in order to build the 3D object.
