The system for making an object from a photopolymerisable material (1) in a liquid or semi-liquid state that can be a seat of two-photon interaction when illuminated by a light beam comprises a multi-source lighting unit (2) allowing a series of light beams (3.1, 3.2) to be focused at different points (30, 31) inside the photopolymerisable material and a unit (DZ) to control the relative displacement of the focusing points within the material. The system for making a three-dimensional object from a photopolymerisable material (1) in a thick layer or a volume in a liquid or semi-liquid state that can be a seat of two-photon interaction when illuminated by a light beam consists of a multi-source lighting unit (2) allowing a series of light beams (3.1, 3.2) to be focused at different points (30, 31) inside the photopolymerisable material, and a unit (DZ) to control the relative displacement of the focusing points within the material, at least in a direction parallel to that of the light beams. A second control unit (DXY) can be use to move a platform (5) supporting a container (10) of the material. Variants of the design can include a spatial light modulator with a pixel matrix that has a distribution pitch greater than the dimension of the focusing points, a concentration matrix, an optical imaging unit, or a series of acousto-optical devices. |
