Abstract

La présente invention concerne un procédé de fabrication additive d’une pièce (1) comprenant une étape de fabrication, par fusion d’une couche de poudre, d’un support mixte présentant au moins une surface plane (21) destinée à supporter de la poudre de fabrication additive non fondue et au moins une aiguille (22) présentant une extrémité de soutien (23) permettant de soutenir une portion de la pièce (1). L’extrémité de soutien (23) de ladite au moins une aiguille (22) se situe à une altitude (A) supérieure à l’altitude (B) de ladite au moins une surface plane (21), de sorte que l’espace (C) entre ladite au moins une surface plane (21) et l’extrémité de soutien (23) de ladite au moins une aiguille (22) puisse être comblé par de la poudre non fondue de fabrication additive pour former un tapis supportant partiellement la pièce (1).
