The invention relates to an additive manufacturing machine (10) for additive manufacturing by deposition of layers of powder and selective consolidation of these layers of powder, the machine (10) comprising a device (18) for depositing layers of powder, a working plane (12), a selective consolidation zone (14), a main jacket (42) of outer contour (Cex), and a secondary jacket (46) arranged inside the main jacket (42) and defining a non-manufacturing zone (48) inside the selective consolidation zone, the device (18) for depositing layers of powder comprising a powder distribution device (22) and a powder spreading device (24), the secondary jacket (42) is closed at the top by a flat closure wall parallel to the working plane (12) of the machine, and the powder spreading device (24) moves in translation above the selective consolidation zone (14) along a rectilinear movement axis (DR). L'invention concerne une machine (10) de fabrication additive par dépôt de couches de poudre et consolidation sélective de ces couches de poudre, la machine (10) comprenant un dispositif de dépôt (18) de couches de poudre, un plan de travail (12), une zone de consolidation sélective (14), une chemise principale (42) de contour extérieur (Cex), et une chemise secondaire (46) disposée à l'intérieur de la chemise principale (42) et définissant une zone de non-fabrication (48) à l'intérieur de la zone de consolidation sélective, le dispositif de dépôt (18) de couches de poudre comprenant un dispositif de distribution de poudre (22) et un dispositif d'étalement de poudre (24), la chemise secondaire (42) est fermée en partie supérieure par une paroi de fermeture plane et parallèle au plan de travail (12) de la machine, et le dispositif d'étalement (24) de poudre se déplace en translation au- dessus de la zone de consolidation sélective (14) le long d'un axe de déplacement rectiligne (DR).
