1. Method of manufacturing a set E of three-dimensional solid components by phototransformation of a polymerizable or crosslinkable organic material, by absorption of light by polymerization or cross-linking photoinitiators, which comprises:
- a) providing at least one source of light radiation;
b) providing automated members for establishing and for superposing, automatically, thin layers of the material;
c) confining the light emitted by the source of light radiation in the form of at least one point of impact on the material;
d) automatically moving said at least one point of impact on the material;
e) storing the geometrical shape of the set E;
f) computing a set of elementary volumes such that, once they are phototransformed, said elementary volumes altogether constitute a set F of components such that E is included in F;
g) controlling and driving all the automated members necessary for the manufacture; and
h) including in the set F of components constructed for the manufacture of the set E, a set G of solid particles, which form during the manufacturing step, a powder of phototransformed material mixed with material still in liquid form, said particles not necessarily having the same geometrical shape.
