A stereolithography machine (1) comprising: a tank (2) provided with a bottom (2a); a modelling plate (3) facing the bottom (2a); a moving unit (4) suited to move the modelling plate (3) according to a direction of movement (Z) that is orthogonal to the bottom (2a); a coupling unit (5) between the modelling plate (3) and the moving unit (4), comprising a first coupling member (6) integral with the moving unit (4) and a second coupling member (7) integral with the modelling plate (3) and movable with respect to the first coupling member (6) according to the direction of movement (Z); tightening means (8) suited to be operated in such a way as to tighten the coupling members (6, 7) against each other according to a tightening direction (X) that is orthogonal to the direction of movement (Z), in order to lock the mutual movement of the coupling members (6, 7). |
