The present invention is a container for a predetermined radiation (4a) so that the solidified by exposure through a liquid or a paste state of the liquid substance (3) (2); And being adapted to discharge a predetermined radiation (4a) so as to selectively irradiated with a layer of said liquid substance (3) in advance with a predetermined thickness In the bottom part of the container (2) in order to solidify the liquid material (3) (2a ) adjacently arranged in the release means (4); Adapted to support the solidified layer 6 modeled plate 5; The modeling to move the plate 5 with respect to the bottom portion (2a) along at least modeling direction (X) perpendicular to the bottom part (2a), the actuator means 7; And the liquid material (3) is flattened means (8 they are combined with the power means so as to move with respect to the bottom portion (2a) of the container (2) in contact with the liquid material (3) in order to ensure that the redistribution in container 2 ); A three dimensional printing machine (1) comprising a. Power means includes two opposed, each one being adapted to move the container (2), said flattening means 8 of the two paddles (9, 10 opposite to each other with respect to the model plate (5) in the direction of the movement direction (Y) ) a.
