Abrégé

A stereolithography method is provided for the production of a three-dimensional object through the superimposition of layers. The method includes: application of a base substance to a supporting surface belonging to a first laminar element and to a second laminar element; selective irradiation of a layer with a predefined thickness of the base substance in contact with the supporting surface in such a way as to obtain a solidified layer; separation of the solidified layer from the supporting surface through a movement intended to move them away from each other. The application of the base substance is carried out by depositing a single layer with thickness at least corresponding to the predefined thickness so that it comes into contact with the second laminar element at least in the areas corresponding to the volume of the three-dimensional object to be obtained.

Abrégé

The invention concerns a stereolithography method for the production of a three-dimensional object through the superimposition of layers on one another. The method comprises the following operations: application of a base substance (2), liquid or pasty and suited to be solidified through exposure to predefined radiation (4), to a supporting surface (3) belonging to a first laminar element (51) and to a second laminar element (52); selective irradiation of a layer with a predefined thickness of the base substance (2) in contact with the supporting surface (3) in such a way as to obtain a solidified layer (2b); separation of the solidified layer (2b) from the supporting surface (3) through a movement intended to move them away from each other. The operation of applying the base substance (2) is carried out by depositing a single layer (2a) with thickness at least corresponding to the predefined thickness so that it comes into contact with the second laminar element (52) at least in the areas corresponding to the volume of the three-dimensional object to be obtained. The operation of selective irradiation is performed on the first laminar element (51) at least in the areas corresponding to the volume of the object to be obtained and at the same time as the operation of applying the base substance (2) to the second laminar element (52). The operation of applying the base substance (2) to the first laminar element (51) is performed before the operation of applying the base substance (2) to the second laminar element (52).

Abrégé

To provide a method for producing an artificial tooth which is excellent in strength, abrasion resistance, hardness, low water absorption, aesthetic property, functionality, and the like within a short time, especially less than 1 hour, smoothly and simply, without requiring skill using a dental photocurable resin composition. [Solution] (c) repeating the operation of the step (b) until the objective artificial tooth is obtained.
