1. A method for physically reconstructing an object using multi-material additive manufacturing, the method comprising:
- receiving tomography data of the object from one or more of a CT scanner, MRI and ultrasound device, wherein the tomography data is in the form of arrays of tomography voxels, each array pertaining to a cross-section of the object and each tomography voxel having a value;
defining a relationship between tomography voxel values and target physical properties for reconstructing the object;
defining a relationship between combinations of modeling materials and their physical properties; and
defining a relationship between tomography voxel values and the material combination responsive to the relationship defined between the voxel values and the target physical properties and the relationship defined between the combinations of modeling materials and their physical properties;
translating tomography data to printable bitmap images representing combinations of modeling materials for reconstructing the object; and
dispensing the combinations of modeling materials responsive to the bitmap images in a layerwise manner, wherein the combinations of modeling materials in each layer are dispensed in a dropwise manner with an additive manufacturing device;
wherein the translating of the tomography data to the printable bitmap images is by raster-raster translation.

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.
