A method for preparing image data for three-dimensional printing in which a physical three-dimensional object is scanned to obtain a digitized (e.g. voxelized) three-dimensional representation of the object. This representation is eroded to create an internal volume for the object. A microstructure is introduced into the interior of the hollowed out model, e.g. by extracting a volume corresponding to the inverse of that microstructure from the eroded digitised representation. Subsequently, the generated internal volume is subtracted from the digitised three-dimensional representation of the object to create a hollowed out representation of the object, which may be suitable for three-dimensional printing. The hollowed out representation of the object may be used to generate a vector based surface representation of the three-dimensional object. |
