Patent application number | Description | Published |
20080247008 | Scanner and method of scanning - A scanner and a method of scanning an image on an original includes an optical sensor having sensor elements for each of three basic colors that is used to generate pixel values of the scanned image. Each pixel value represents an optical density of a pixel of the image and is generated mainly on the basis of a signal of only one of the sensor elements. Each of the sensor elements for each of the basic colors is used to generate pixel values representing substantially different parts of the image. | 10-09-2008 |

20120007287 | METHOD AND APPARATUS FOR LAYERWISE PRODUCTION OF A 3D OBJECT - A system and method for layer-by-layer production of an object is provided. The system includes a construction shape having a carrying surface adapted for carrying a layer of build material, a plate having a holding surface adapted for holding an object in an object build area, a moveable reservoir having a plurality of containment surfaces defining a containment area adapted for containing a volume of build material within the moveable reservoir, and an exposure unit adapted for exposing at least a portion of the layer of build material in the object build area so that the portion of the layer of build material solidifies to form a solidified layer of the object. In one embodiment, the moveable reservoir is moveable between a first position and a second position and at least one of the plurality of containment surfaces of the moveable reservoir includes a portion of the carrying surface when the moveable reservoir is in the first position, and the portion of the carrying surface is positioned in the object build area when the moveable reservoir is in the second position. | 01-12-2012 |
20120057143 | Illumination System for Use in a Stereolithography Apparatus - The invention concerns an illumination system for use in a stereolithography apparatus, comprising: a planar support; a multilens projector array mechanically supported on the planar support over the array on a plano side, and having a work surface arranged to receive a resin applying device for applying a resin layer, the projector array comprising a stack of optical elements, including a plurality of lenslets adapted to project the LEDs onto the work surface, and a two-dimensional array of individually controllable light-emitting diodes (LEDs) arranged between the planar support and the multilens projector. According to an aspect, the planar support and the plano side are supported on contact zones arranged over substantially the entire plano side; the illumination system thus forming a rigid body. | 03-08-2012 |
20120063131 | Illumination System for Use in a Stereolithography Apparatus - The invention concerns an illumination system for use in a stereolithography apparatus, comprising a planar support supporting a two-dimensional array of individually controllable wide-angle light-emitting diodes (LEDs); and a multilens projector array arranged relative to the array, and adapted to project a focused image of the LEDs onto a work area. The multilens projector array is arranged to project light from the LED array having a light emitting edge area image spot size which is smaller than or equal to a light emitting central area image spot size. | 03-15-2012 |

20130213567 | FOIL GUIDING SYSTEM FOR ADDITIVE FABRICATION - 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. | 08-22-2013 |
