Modeling plate for a stereolithography machine, stereolithography machine using said modeling plate and tool for cleaning said modeling plate

摘要

The invention is a modeling plate (6; 6′; 6″) for a stereolithography machine (1) suited to produce three-dimensional objects (A) through superimposition of a plurality of layers (E) with predefined thickness of a liquid substance (3) that solidifies when subjected to a selective stimulation (4). The plate (6; 6′; 6″) comprises a work surface (7) that supports the object (A) and grooves (8) made in the work surface (7) along a development trajectory (X).

主权项

1. A method for the stereolithographic production of a three-dimensional object, the method comprising: providing a tank suited to contain a liquid substance; providing a modelling plate comprising a work surface and a lateral surface, the work surface facing the bottom of the tank and suited to support the object, the modelling plate comprising at least one groove in the work surface along a development trajectory and extending to a perimeter edge of the work surface so as to have at least one open end in the lateral surface of the modelling plate; submerging the work surface of the modelling plate in the liquid substance so that a portion of the liquid substance is in the at least one groove, providing selective stimulation to the liquid substance to solidify the liquid substance in a plurality of superimposed layers each having a predefined thickness, maintaining a liquid layer of the liquid substance between the solidified object and the modeling plate in the at least one groove during the provision of selective stimulation.
