通过增材制造技术制造由陶瓷材料制成的坯件的方法
摘要：
在立体成型机的工作平台(1)上，通过增材制造技术同时但分开地由相同的糊状光固化性陶瓷组合物制造：由生坯件的支撑件(2)和该支撑件上的生坯件构成的半成品组件，支撑件的自由表面带有生坯件的第一面部的印记；以及由陶瓷材料制成的坯件构成的半成品成形器(4)，该半成品成形器的自由表面带有生坯件的与第一面部相对的第二面部的印记；在窑炉中，将由此获得的半成品组件放置在由此获得的半成品成形器(4)上，该半成品成形器的印记转动成向上，该半成品组件的生坯件转动成向下，以使该生坯件接收在成形器(4)的印记中，并且使由此保持在成形器(4)和支撑件(2)之间的生坯件进行脱脂和烧结。
摘要（英）：

On a working platform 1 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 2 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 4, whose free surface bears the imprint of a second face of the green piece opposed to the first face, made of ceramic material parts; in a kiln, is placed, on the green shaper 4 thus obtained withits 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 4, and the green piece thus held betweenthe shaper 4 and the support 2 is subjected to debinding and to sintering.
