摘要： A method cycle of a method for layerwise production of a tangible object (5) comprises the successive steps of: solidifying predetermined parts of a liquid so as to obtain a solid layer (14) having a predetermined shape; separating said solid layer from a construction shape (6); and moving, relative to one another, the separated solid layer and the construction shape to a predetermined position relative to one another. Solidifying is carried out such that the solid layer and the construction shape have nonmatching shapes in the sense that all surface portions of a solid layer side (70) that are or have been in contact with a liquid contacting side (11) of the construction shape can not simultaneously be brought in full contacting engagement with the liquid contacting side.

摘要： A method for layerwise production of a tangible object comprises repeatedly performing method cycles. Each method cycle comprises the steps of solidifying a predetermined area of an uppermost liquid layer (10) of a liquid (3) in a reservoir (2), so as to obtain a solid layer of the tangible object, and creating, above, parallel and adjacent to the solid layer, a successive uppermost liquid layer of the liquid. Said creating of the successive liquid layer is carried out by spraying such liquid onto upper parts of the contents in the reservoir. A height distribution over at least part of the surface of the uppermost liquid layer is measured by means of a measuring device (6). Based on the measured height distribution, the solidifying is carried out to compensate for unflatness of the measured height distribution.

摘要： An additive fabrication apparatus with an efficient reversal mechanism to reverse the orientation of foil guiding rollers is contemplated. To this end, according to an aspect, a foil guiding system comprising: a flexible foil guiding roller; and a bearing system arranged to bear said guiding roller, said bearing system comprised of end locking elements axially locking to the roller; a bearing arrangement defining a bearing position having the roller curved in bearing engagement. The bearing arrangement engages with an outer face of said roller in a manner so as to thereby flex the roller between at least two bearing positions in conformity with a rolling direction. The flexible roller in connection with the outside bearings replaces a fixed shaft arrangement of the prior art, which is easily tunable to the foil movement direction.
