  • Patent number: 11365157
    Abstract: On a working platform of a stereolithography machine, is manufactured, by the technique of additive manufacturing, simultaneously but separately, from a same pasty photocurable ceramic composition: a green assembly made up of a support of the green piece and of the green piece on the support, the free surface of the latter imprinted by a first face of the green piece; and a green ceramic shaper whose free surface bears the imprint of a second face of the green piece opposed to the first face; in a kiln, is placed, on the green shaper thus obtained with its imprint turned upwards, the green assembly thus obtained with its green piece turned downwards in order for it to be received in the imprint of the shaper, and the green piece thus held between the shaper and the support is subjected to debinding and to sintering.

  • Patent number: 11090725
    Abstract: The disclosed method includes selecting a suspension ceramic or metal photocurable composition (CPC or MPC); preparing a sacrificial organic material (SOM) forming a photocurable layer destroyed by heating; for manufacturing pieces, on the working tray, forming successive layers of SOM cured by irradiation, the one or more CPC or MPC-based pieces being manufactured by machining a recess in a layer of cured SOM; depositing the CPC or MPC within the recesses; curing the CPC or MPC to obtain a hard horizontal surface level with the adjacent layer of cured SOM, when forming each recess, it is delimited by previously defined patterns, the depth(s) selected in order to ensure the continuity of the one or more pieces to be manufactured; and obtaining one or more green pieces inserted in the SOM, which are subjected to debinding by heating in order to destroy the SOM in which they are trapped.

  • Patent number: 10639156
    Abstract: Disclosed is a synthetic block intended for filling in a bone defect. The block is made up of a part made of ceramic material which has a shape that enables same to fill in the bone defect, and which is capable of being stabilized once placed in the bone defect, a three-dimensional network of channels communicating with one another being formed at least partially in the part such as to allow through the fluids and cells that enable revascularization with a view to cell growth once the part is in place in the bone defect, the channels opening onto each surface of the bone defect in contact with the part once it is placed in the bone defect.

  • Patent number: 9192475
    Abstract: A cranial implant designed to fill a cranial defect of the skull of a mammal or a human, wherein the cranial implant is made of biocompatible ceramic and includes an implant body having a shape and size substantially matching the shape and size of the cranial defect to be filled, wherein the implant body includes an outer face facing outside the skull and an inner face facing inside the skull when the implant disposed on the skull, characterized in that the implant includes one or more reinforcing members protruding from the inner face of the implant body. A method of manufacturing the cranial implant is also described.

  • Publication number: 20120245024
    Abstract: A method for manufacturing a catalyst support, includes, in the following order, the steps of: (a) shaping a non-sintered porous ceramic base support; (b) depositing, on at least part of the surface of the non-sintered porous ceramic base support, a suspension of ceramic powder in a solvent or a mixture of solvents so as to form an interface layer able to increase the surface area of the base support; (c) sintering the base support, at least partially coated with the suspension. This method allows to economically and rapidly manufacture catalyst supports, and especially burners for fragrance diffuser.
