<p>The invention relates to a three-dimensional printer suitable for printing three-dimensional parts and prototypes (4) in light-curable resin (2), said three-dimensional printer comprising: a secure horizontal tray (1) containing the resin (2) and disposed above the light source (3); a vertical modelling platform (5) which is mounted on an actuating device and can tilt laterally between two end positions, forming two acute angles in opposing directions in relation to the horizontal. The actuating device is provided with: two vertically moveable supports (6) on which are mounted two opposing ends of a bridge (8) carrying the platform (5), such that they can rotate relative to respective horizontal axes (7); and linear actuators (11-13) that can be actuated independently. The linear actuators comprise threaded sleeves (13) secured to the respective supports (6) that are moveable and mounted on respective vertical spindles (11) connected to respective independently actuated stepper motors (12). The moveable supports (6) comprise respective linear bearings (9) mounted such that they can move longitudinally on the vertical guides (10).</p> |
