  • Publication number: 20210024422
    Abstract: Disclosed is a method for manufacturing, by stereolithography, a green part made of a ceramic or metallic material. Layers based on a curable composition including: the ceramic or metallic material formed by at least one ceramic or metallic powder, respectively, and an organic part including at least one monomer and/or oligomer and at least one initiator for the polymerization of the one or more monomers and/or oligomers, are successively cured by the polymerization according to a pattern defined for each layer. The first layer formed on a construction platform, each other layer being formed and then cured on the preceding layer. As an initiator, at least one thermal initiator is used capable of generating the initiation of a thermal polymerization by the thermal energy released by the ceramic or metallic material, respectively, during exposure to at least one irradiation source chosen from UV, visible or IR irradiation sources.

  • Patent number: 10335288
    Abstract: An apparatus and method is provided relating to artificial discs. An artificial disc is provided that facilitates simultaneous and independent articulation of flexion/extension, lateral bending, anterior/posterior translation, and axial rotation. The artificial disc provides these four simultaneous and independent articulations by independently addressing each type of articulation in the design of the artificial disc. In one example, an artificial disc is comprised of a bearing disposed between first and second end plates. The bearing is movable relative to each end plate, independent of the other end plate. The end plates are affixed to adjacent vertebrae.

  • Publication number: 20190015899
    Abstract: In a method of manufacturing, before making the first layer: the working tray is covered with a support sheet able to be biased against it, forming a rigid and fixed surface for receiving the successive layers, which is able to hold thereon the successive layers as formed; and the support sheet is biased against the working tray; the green piece is formed by the technique of additive manufacturing; and when the green piece is thus formed, the biasing is suppressed in order to detach, from the tray, the support sheet on which the green piece is located with the portion of the photocurable composition which has not been cured; the non-cured photocurable composition portion is removed; and the green piece is unhooked from the support sheet.

  • Publication number: 20180250845
    Abstract: Disclosed is a method for manufacturing a piece, especially a green piece made of ceramic material, by the technique of additive manufacturing according to which layers of a photocurable paste are successively allowed to cure according to a pattern defined for each layer, the first layer being formed on a working surface on a working tray, each layer, before curing according to a defined pattern, being spread by scraping by one scraping blade or parallel scraping blades from an amount of paste supplied onto the working tray, which is lowered upon each formation of a layer. Upon each formation of a layer, the amount of paste necessary to form the layer is dispensed onto the working surface, from at least one nozzle which is moved in front of the scraping blade, or in the case of parallel scraping blades, in front of the front scraping blade.
