Abstract

L'invention concerne des systèmes et des procédés de fabrication additive faisant appel à un modulateur de lumière optique conçu pour moduler spatialement l'intensité d'un faisceau laser, conjointement avec un sous-système d'écriture et d'effacement configuré pour écrire et effacer de manière répétée des motifs du modulateur de lumière optique de façon à varier de manière répétée la modulation spatiale du faisceau laser. Selon certains modes de réalisation, les systèmes et les procédés peuvent également faire appel à des faisceaux laser supplémentaires ou à d'autres sources d'énergie qui ne sont pas modulés spatialement par le modulateur de lumière optique. Selon certains autres modes de réalisation, les systèmes et les procédés peuvent faire appel à des faisceaux laser supplémentaires ou à d'autres sources d'énergie conçus pour réduire la rugosité de surface de la poudre ou d'un autre matériau utilisé pour la fabrication additive.
