Three-dimensional model generation

A system, comprising:

• an analysis module comprising at least one scanner to analyze a structure of an object and to analyze compositions of components of the object;
• and
• a modeling module comprising a processor receiving input from the analysis module to generate a three-dimensional model of the object based on the structure of the object and based on compositions of components of the object;
• and
• an additive manufacturing device to replicate the object by additive manufacture based on the three-dimensional module of the modeling module;
• wherein the three-dimensional model comprises a number of voxels, each voxel representing and corresponding to a particular location in three-dimensional space within the object;
• wherein each voxel comprises location information specifying a particular location of that voxel in three-dimensional space;
• wherein each voxel also specifies both physical attributes and chemical attributes, including composition, of that location within the object;
• and
• wherein the scanner of the analysis module further comprises a surface profiler to profile a surface of the object, the modeling module to incorporate data from the surface profiler into voxels of the three-dimensional model of the object that correspond to the surface of the object.

A 3D modeler, comprising:

• a structure analysis module to analyze a physical structure of an object, including material density at various locations in the object;
• a composition analysis module to analyze a composition of the object;
• a modeling module to generate a three-dimensional model of the object, where the three-dimensional model includes data describing physical attributes of the object, including material density at various locations in the object, that are generated based on the physical structure of the object, and where the three-dimensional model includes data describing the composition of the object;
• wherein the three-dimensional model comprises a number of voxels, each voxel representing and corresponding to a particular location in three-dimensional space within the object;
• wherein each voxel comprises location information specifying a particular location of that voxel in three-dimensional space;
• and
• wherein each voxel also specifies both physical attributes, including material density, and chemical attributes, including composition, of the corresponding location within the object.
