Abstract: A method for physically reconstructing a body part using multi-material additive manufacturing includes receiving image data of the body part in the form of arrays of voxels, each array of voxels representing image data pertaining to cross-section of the body part, translating the image data in the arrays of voxels to printable bitmap images representing combinations of modeling materials for reconstructing the body part, and dispensing the combinations of modeling materials responsive to the bitmap images in a layerwise manner.

Abstract: A method for slicing a three-dimensional model for printing of a corresponding object by a 3D printer, comprises: obtaining the envelope of the object as polygons, then for each region of a predefined work area within the slicing plane:identifying the closest polygon of said envelope that is positioned above said respective pixel; where no polygon is identified, then marking a corresponding region as a no-print region; if the direction vector of said closest above polygon has a positive component in the Z direction, then marking said corresponding region as a model region; and if the direction vector of said polygon has a negative component in the Z direction, then marking the region as a support region, and printing accordingly. An advantage of the above procedure is that the slicing, and in addition texture mapping, can be efficiently carried out on a graphics card or GPU.
Abstract translation: 一种用于通过3D打印机对用于打印相应对象的三维模型进行切片的方法，包括：获取所述对象的包络作为多边形，然后对于所述切片平面内的预定义工作区域的每个区域：识别最接近的多边形 所述包络位于所述相应像素上方; 其中没有识别多边形，然后将对应的区域标记为无打印区域; 如果所述最近的多边形的方向矢量在Z方向上具有正分量，则将所述对应的区域标记为模型区域; 并且如果所述多边形的方向矢量在Z方向上具有负分量，则将该区域标记为支撑区域，并相应地进行打印。 上述过程的一个优点是可以在显卡或GPU上高效地执行切片（另外还有纹理映射）。

Abstract: A method of printing a three-dimensional (3D) color object, layer-by-layer, comprises: obtaining a 3D CAD specification defining a 3D geometry and a surface color distribution for the color object to be printed, defining regions on a surface of the color object; defining colors for each region based on the CAD specification; determining, using the 3D geometry of the specification, conditions applying at respective regions that are liable to cause color variation, such that using the colors as defined at the respective regions may give rise to a coloration error; selecting color corrections defined for respective determined conditions; correcting the defined colors; and printing the 3D color object with the color corrections.
