Abstract
A device for keeping the liquid level constant during 3D printing includes a liquid bath for containing printing liquid, a printing platform for carrying a printed sample, a liquid level counterbalance inserted into the liquid bath, and a link mechanism connected with the printing platform and the liquid level counterbalance respectively for driving the liquid level counterbalance to ascend when the printing platform descends. The printing platform is inserted into the liquid bath and driven by a lifting device to ascend or descend. The printing platform and the liquid level counterbalance are in a relationship that a volume of a portion of the printing platform immersed into the printing liquid due to descending of the printing platform is equal to a volume of a portion of the liquid level counterbalance leaving the printing liquid due to rising of the liquid level counterbalance caused by descending of the printing platform.
