Abstract
The present invention relates to a method for producing a 3D object and to a system adapted to implement the method, wherein the method comprises: —providing a powder material (G); —providing a radiation absorbent material, in the form of optically resonant particles (P), on a region to be sintered of the powder material; and—sintering the region to be sintered of the powder material (G), by exposing to light the optically resonant particles (P) to radiation. The method comprises providing the optically resonant particles (P) according to a distribution and proportion, with respect to the powder material (G) included in the region to be sintered, selected: —to disperse the optically resonant particles (P) within the powder material (G) included in said region, and—to avoid substantial agglomeration and substantial self-sintering of the optically resonant particles (P).
