A stereolithographic machine (10) for making three-dimensional objects (21) in layers, comprising a vessel (13) containing a fluid or powder which is solidified through exposure to a defined radiation, means for emitting said radiation which are configured to irradiate selectively one layer of predefined thickness of the fluid or powder, which is placed adjacent to the bottom (15) of the vessel (13), and a rotating modeling head (20) which has a plurality of working surfaces (22), which lie on respective different planes, provided with grooves (25), in order to allow short machining times. |
