METHOD FOR MANUFACTURING PIECES MADE OF CERAMIC MATERIAL BY THE TECHNIQUE OF ADDITIVE MANUFACTURING
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.
