摘要

Method for obtaining three-dimensional articles, in which a sheet (2A, 2B, 2C), composed of a material whose solubility varies when it is subjected to a specific radiation and of fibres or of a reinforcing weft, is prepared, the sheet having a stiffness sufficient for being manipulated and being able to adhere to a similar sheet. The sheet is subjected to the said radiation (18) in a defined zone, then a new sheet is fixed to it and the transmission of radiation is recommenced and then the stack is subjected to a selective dissolution which reveals the desired article (31). ……
