Abstract: Provided are a resin reservoir (1) for photocuring for use in a 3D printer and a 3D printer using the resin reservoir (1). The resin reservoir (1) comprises: a reservoir body (11) for accommodating a liquid photosensitive resin, at least one side wall of the reservoir body (11) being an optically-transmissive wall (111); a transverse guide element (12) disposed at the reservoir body (11); and a load-bearing element (13) disposed inside the reservoir body (11) and capable of moving transversely along the guide element (12), wherein a load-bearing surface of the load-bearing element (13) faces the optically-transmissive wall (111). The resin reservoir (1) and the 3D printer enable a printed object to be transversely formed at the load-bearing element (13) and kept immersed in the liquid photosensitive resin, and a buoyancy provided by the liquid photosensitive resin can substantially offset the weight of the printed object.

Abstract: A photocuring 3D printer includes: a resin tank including a tank body for containing a liquid photosensitive resin, at least one side wall of the tank body being an optically-transmissive wall; a transverse guide element arranged on the tank body; and a load-bearing element arranged inside the tank body and movable transversely along the guide element, a light source provided outside the optically-transmissive wall, and an LCD display unit having a same area as the optically-transmissive wall and covered at an outer side or an inner side of the optically-transmissive wall.
