Methods for removing an object from powder after forming the object in an additive manufacturing apparatus are provided. The method may include: positioning a cover over a build platform with the object being positioned within a powder; removing the build platform from the additive manufacturing apparatus with the cover positioned over the build platform; and thereafter, removing the powder from the build platform to expose the object.

Methods for removing loose particles from an object built by additive manufacturing

An additive manufacturing apparatus may include a process chamber, a coating device, a shielding device, and a guiding device. The process chamber may include first and second working plane areas. The first working plane area may include a construction plane, and the second working plane area may house at least a part of the guiding device. The coating device may include a coating element assembly group that is, movably supported relative to the construction plane by the guiding device, and at least one coating element configured to form construction material layers in the construction plane. The shielding device may shield the second working plane area from intrusion of construction material or impurities from the first working plane area. The shielding device may include a shielding band, and the shielding band may be coupled for movement with the coating element assembly group. The shielding band may be guided movably along a plurality of supporting points that define an interior region of the second working plane area, and the guiding device may be arranged or formed above the first working plane area.
