A method of preparing image data for three-dimensional printing in which a digitised (e.g. voxelized) representation of a virtual three-dimensional object (e.g. CAD model) is eroded to create an internal volume of the object. Subsequently, a vector-based surface representation of this internal volume is generated and combined with a corresponding vector-based surface representation of the original virtual three-dimensional object to yield a hollowed out model in a format suitable for three-dimensional printing. A microstructure may be introduced into the interior of the hollowed out model for example by extracting a volume corresponding to the inverse of that microstructure from the eroded digitised representation. |
