Abstract
The invention is a stereolithography machine (1) comprising: a container (2) suited to contain a fluid substance (3) suited to solidify through exposure to predefined radiation (4a); means (4) suited to emit the predefined radiation (4a) and to solidify a layer of the fluid substance (3) having a predefined thickness and arranged adjacent to the bottom (2a) of the container (2); a modelling plate (5) suited to support the solidified layer (6); actuator means (7) suited to move the modelling plate (5) according to a direction perpendicular to the bottom (2a) of the container (2); levelling means (8) arranged in contact with the fluid substance (3), associated with power means suited to move them with respect to the container (2) so as to redistribute the fluid substance (3) in the container (2). The power means are configured so as to move the container (2) in each one or the two opposite senses of a direction of movement (Y) and the levelling means (8) comprise two paddles (9, 10) that are opposite each other with respect to the modelling plate (5).
