Abstract: Systems and methods for continuous printing of a three-dimensional (3D) object are provided. The system includes a resin tank, an optical image source, a support fluid reservoir and a pumping structure. The resin tank is where the 3D object is printed and includes a print bed to form a base of the 3D object. The optical image source modulates light in accordance with a 3D image to vary a degree and pattern of crosslinking in a photocrosslinkable resin in the resin tank. The support fluid reservoir is in fluid communication with the resin tank and includes a support fluid which is immiscible with the photocrosslinkable resin. And the pumping structure is configured to transfer the support fluid from the support fluid reservoir to the resin tank such that the support fluid rises in the resin tank at a same rate as vertical height of a top of the 3D object as the 3D object is printed on the print bed.
