Abstract (en)
[origin: CA3089776A1] The invention relates to a device for treating 3D powder printing elements, in particular 3D laser printing elements and/or 3D powder bed elements, in particular produced using a plastic powder laser sintering method, comprising at least one first chamber, at least one first partial chamber and a second partial chamber, separated by at least one screen grid means, wherein the grid meshes are adaptively designed to allow compressed powder residues to pass through, a rotation means for rotating the first chamber about an axis of rotation, in particular with a rotary passage, wherein the screen grid means is inclined, in particular perpendicular, to the axis of rotation of the first chamber, a filling region for filling the 3D powder printing elements into the first partial chamber chamber, gas medium supply means, in particular air supply means, in the first chamber, in particular in the first partial chamber, gas medium suction means, also designed to extract plastic powder residues from the first chamber, in particular from the second partial chamber, wherein the gas medium suction means are to be mounted in particular in or parallel to the axis of rotation and/or centred by the rotary means, in particular within the rotary passage.
