Abstract:
A method of solid free-form fabrication (SFF) includes receiving SFF data collectively pertaining to a three-dimensional shape of the object and comprising a plurality of slice data each defining a layer of the object. The method further includes dispensing a building material containing a solvent, drying the building material so as to remove at least some of the solvent from the building material and leveling the building material. The method further includes selectively ablating the building material, for at least several of the multiple layers, according to the slice data corresponding to the layer, and dispensing at least one additional building material onto the building material to fill vacant regions formed in the multiple layers by the selective ablation. A resolution of the dispensing of the additional building material may be less than a resolution of the selective ablation.
