Abstract

L'invention concerne un système de fabrication additive à haute résolution basé sur un procédé d'impression parallèle utilisant un modulateur spatial de lumière. L'invention concerne également un procédé et un système de fabrication additive à l'aide d'un DMD dans le trajet de faisceau laser. L'invention fait appel à l'utilisation d'un faisceau laser de préchauffage en combinaison avec un faisceau laser construit ayant un DMD le long du trajet de faisceau laser construit.
