摘要： 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.

摘要： A 3D screen-printing apparatus for producing a shaped article includes: a printing table; a printing screen with a printing mask having a layer geometry for producing the shaped article layer by layer; an application unit to apply a printing material to the printing screen and to work it into the printing masks to produce a shaped-article layer; and a first positioning unit configured to increase the distance between the printing table and the printing screen by way of a first relative movement after the production of each shaped-article layer. The printing screen has printing masks, and the 3D screen-printing apparatus has a second positioning unit configured to perform a second relative movement between the printing table and the printing screen so different printing masks of the one printing screen can be positioned one after the other at a shaped-article position where an individual shaped article is to be built.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
