STEREOLITHOGRAPHY APPARATUS
First Claim
1. A stereolithography apparatus configured to fabricate a three-dimensional model by forming a cured layer by irradiating an interface of a photocurable resin with light corresponding to sectional data of the three-dimensional model and staking the cured layer, the stereolithography apparatus comprising:
- a container holding the photocurable resin and having a constraining window configured to constrain the interface of the photocurable resin;
a vertical movement table movable in a vertical direction orthogonal to the interface of the photocurable resin;
an optical system configured to form the cured layer between the vertical movement table and the constraining window by irradiating the interface of the photocurable resin with light through the constraining window; and
a position constraining mechanism configured to substantially flatten the constraining window by applying a force to the constraining window from the outside of the container when the cured layer is formed by the optical system.

6. A stereolithography apparatus configured to fabricate a three-dimensional model by forming a cured layer by irradiating an interface of a photocurable resin with light corresponding to sectional data of the three-dimensional model and stacking the cured layer, the stereolithography apparatus comprising:
-
a container holding the photocurable resin and having a constraining window configured to constrain the interface of the photocurable resin; a vertical movement table movable in a vertical direction orthogonal to the interface of the photocurable resin; an optical system configured to form the cured layer between the vertical movement table and the constraining window by irradiating the interface of the photocurable resin with light through the constraining window; pressure detecting means for detecting pressure applied to the vertical movement table; and contact detecting means for detecting contact between the vertical movement table and the constraining window on the basis of a change in pressure detected by the pressure detecting means, wherein, when stacking the cured layer, the vertical movement table moves in the vertical direction with reference to a position of the vertical movement table in the vertical direction when contact is detected by the contact detecting means.
