Abstract: Disclosed is a sintering system for manufacturing a three-dimensional object from sinterable powder. The system comprises a build chamber with a movable floor and four walls, an energy assembly disposed above the build chamber and which comprises at least one energy source adapted to emit an energy beam. The system further comprises a feeding assembly connected to the build chamber for providing sinterable powder to the build chamber and a powder distribution device connected to the feeding assembly for distributing sinterable powder in the build chamber. The build chamber further comprises at least one opening in at least one wall, below which the movable floor can be lowered, and a pneumatic assembly connected to the build chamber for transporting powder away from the build chamber through the at least one opening.

Abstract: Disclosed is a package (100) for powder for additive manufacturing comprising a body (110), a top (120), and a bottom (130), wherein the bottom (130) comprises a first part (200) having an inlet aperture and an outlet aperture, and a second part (300) having an inlet aperture and an outlet aperture. The second part is displaceable relative to the first part and in a closed position, the first part (200) is offset relative to the second part (300), such that neither of the inlet aperture and the outlet aperture of the first part (200) overlap with either of the inlet aperture and the outlet aperture of the second part (300). In an open position, the inlet aperture of the first part (200) is aligned with the inlet aperture of the second part (300) and the outlet aperture of the first part (200) is aligned with the outlet aperture of the second part (300).
