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).

Abstract: Disclosed is a method for calculating a tool path for additive manufacturing, comprising obtaining (S110) a three-dimensional model describing an object to be formed, dividing (S120) the model into a plurality of layers, and analyzing (S120) each layer of in order to obtain at least one outline of each layer. The method further comprises analyzing (S130) each outline to obtain an inside and outside for each outline of each layer. It further comprises determining (S140) a smallest rectangle that encloses each outline, calculating (S150) an infill curve for each rectangle, using a Hilbert* algorithm. The method further comprises overlaying (S160) the outline on its corresponding rectangle, and determining (S170) which parts of the infill curve are on the inside of the outline, thus obtaining a tool path for the outline comprising at least one infill curve and the outline.
