  • Patent number: 11259904
    Abstract: A digital integrated molding method for dental attachments includes 3D design, aiming at acquiring 3D data of an attachment itself through 3D scanning of an attachment preform, carrying out modeling design directly on the basis of acquired data, adjusting corresponding positions of an inner-crown and an attachment, or a bridge and an attachment by design software, and directly designing the attachments of the inner-crown and the bridge into a whole; data processing, aiming at slicing the integrated inner-crown and attachment or bridge and attachment for additive manufacturing; and additive manufacturing, aiming at processing an integrated inner-crown, bridge or attachment. The molding method can greatly improve the molding accuracy of dental attachments, and ensure the relative accuracy of inner-crowns, bridges or attachments.

  • Publication number: 20210060646
    Abstract: A method for forming precise porous metal structure by selective laser melting, including 3D design, data processing, parameter setting and selective sintering, including the following steps: A. designing 3D model of precise and porous structure; B. adding support structure and slicing; C. setting parameters of laser scanning and beam offset; and D. arranging a soft recoater in the forming system. After coating the metal powder on the forming plate, the fiber laser emits a laser to melt the metal powder to form a single-layer cross section of the porous structure; E. lowering the forming plate by one layer, and repeating steps D-E, so that the metal powder is melted and accumulated layer by layer until the formed components of porous structure are obtained.
