  • Patent number: 11938678
    Abstract: Disclosed herein are an adhesion blocking element, a three-dimensional printing device and a three-dimensional printing method. The adhesion blocking element comprises: one light-transmittable main body comprising a first surface and a second surface which are disposed opposite to each other, and side faces connecting the first surface and the second surface; and a plurality of microstructures arranged on the main body, wherein each microstructure has one cavity formed in the main body and one first open face which is arranged on the first surface of the main body and communicated to the cavity. The present invention decreases the adhesion between the adhesion blocking element and the cured layer by improving the structure of the adhesion blocking element itself, and eliminates the negative pressure adsorption between the cured layer and the adhesion blocking element, so that it is easier to peel the adhesion blocking element off from the cured layer.

  • Patent number: 11938675
    Abstract: The present invention discloses a three-dimensional printing device, comprising: a chassis, a light source and a controller, wherein a liquid storage tank is arranged in the middle of the chassis, an anti-sticking element is arranged on the inner wall of the liquid storage tank, and the liquid storage tank is used for holding polymerizable liquid; and further comprising: a base which is adapted to the liquid storage tank in a para-position way, wherein the base is connected with a driving device, and the light source is matched with the bottom of the base. By using the anti-sticking element as a covering part for the liquid storage tank, the forming part formed by curing the polymerizable liquid can lose contact with the anti-sticking element quickly and efficiently, so as to carry out further formation and processing operations. In this way, the whole three-dimensional printing process is more rapid and efficient.

  • Publication number: 20220324165
    Abstract: The present disclosure relates to systems and methods for treating a printed model. The methods may include placing at least a portion of the printed model into a heat treatment medium. The methods may further include performing a heat treatment on the printed model based at least in part on the heat treatment medium. The heat treatment medium may provide a constraint force to prevent a deformation of the printed model during the heat treatment. And the methods may also include obtaining a printed object based at least in part on the heat treatment performed on the printed model.

  • Patent number: 11173655
    Abstract: A 3D printer uses slides to illuminate the photocurable liquid. A slide carrier holds one or more slides that contain different patterns. To form each layer of a three-dimensional part, the corresponding pattern is projected onto the photocurable liquid, thus forming that layer. A controller switches the slides as needed, coordinating the slides with formation of the three-dimensional part.
