| 摘要 |
The invention relates to a method for the layered construction of a shaped part (11) from a highly-viscous photopolymerisable material, where layers (10) of said shaped part are formed one after the other and one on top of the other, a material layer (6) of a predetermined thickness (a) of said highly-viscous photopolymerisable material being formed in a basin (1), and the construction platform (5), or the shaped part (11) at least partially formed on said construction platform (5), being lowered into the material layer (6) such that, between said construction platform (5) or shaped part (11), and the base (2) of the basin, a layer of said highly-viscous photopolymerisable material is formed which, in particular, is cured by means of locationally-selective irradiation through the base (2) of the basin in order to form the desired shape for the shaped part layer (10). In said method, the thickness (a) of the material layer (6) during construction of the shaped part (10) is varied at least once. The invention also relates to a device for carrying out said method. |
