Stereolithography machine with improved optical unit

Title:

Stereolithography machine with improved optical unit

Document Type and Number:

Japanese Patent JP6331096

Kind Code:

B2

Abstract:

Stereolithography machine (1) comprising: a container (2) for a fluid substance (14); a source (3) of predefined radiation (3a) suited to solidify the fluid substance (14); an optical unit (4) suited to direct the radiation (3a) towards a reference surface (5) in the fluid substance (14); a logic control unit (6) configured to control the optical unit (4) and/or the source (3) so as to expose a predefined portion of the reference surface (5). The optical unit (4) comprises a micro-opto-electro-mechanical system (MOEMS) (7) provided with a mirror (8) associated with actuator means (7a) for the rotation around at least two rotation axes (X, Y) incident on and independent of each other, arranged so that it can direct the radiation (3a) towards each point of the reference surface (5) through a corresponding combination of the rotations around the two axes (X, Y).
