Abstract
Process for obtaining three-dimensional objects, according to which process a sheet (2A, 2B, 2C) is prepared, which sheet is composed of a material, the solubility of which varies when it is subjected to a specific radiation, and of fibers or of a screen for reinforcement, the sheet having a sufficient rigidity to be handled and being capable of adhering on a similar sheet. The sheet is subjected to said radiation (18) in a defined zone, and then a new sheet is fixed onto it and the passing of radiation is recommenced, and then the stack is subjected to a selective dissolving which causes the desired object (31) to appear.
