Claim:
1. A stereolithography machine comprising: a container for a fluid substance suited to be solidified through exposure to radiation; a laser source for providing said radiation, said radiation including a laser light with a visible or ultraviolet frequency; an optical unit operable to selectively direct said radiation towards any point of a reference surface arranged inside said container; and a logic control unit configured to control said optical unit and/or said laser source in such a way as to scan and solidify a portion of a volume of the fluid substance adjacent to said reference surface, wherein said optical unit comprises a micro-opto-electro-mechanical system (MOEMS) including: wherein said mirror is arranged with respect to said laser source and to said container in such a way as to be able to direct said radiation towards each point of said reference surface through a corresponding combination of rotations around said two axes, and wherein said actuator is configured so as to rotate said mirror around each one of said two axes in such a way as to arrange said mirror in an angular position in response to a control signal emitted by said logic control unit, said control signal having a value corresponding to said angular position.
