  • Patent number: 11584077
    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.

  • Patent number: 10399270
    Abstract: Disclosed is a photo-curing 3D printer comprising a storage unit for accommodating liquid photosensitive resin and a light source disposed underneath the storage unit. Wavelength of light rays emitted by the light source is 420˜460 nm. A bottom of the storage unit is configured to display a pattern composed of a shielding area for shielding the light rays and a transmissive area for passing-through of the light rays. In addition, the disclosure provides a 3D printing method. Due to the limitations of photopolymerization initiators and the LCD display unit currently available, it was unexpected to complete photo-curing 3D printing with a light source with 420˜460 nm wavelength. It is unexpected that a photo-curing 3D printer as provided in the present application not only can ensure the service life of the LCD display unit but also that the curing efficiency is significantly higher than existing devices.
