Abstract

The present invention relates to a three-dimensional imaging process for making objects, preferably metal objects or ceramic objects, on a layer-by-layer basis under the control of a data processing system. The process includes the steps of (i) providing a supply of mold building material in filament form; (ii) providing a supply of crafting medium in paste form; (iii) providing a dual printhead including a first dispensing nozzle and a second dispensing nozzle; (iv) feeding the filament to enter one end of a flow passage of the first dispensing nozzle having a first discharge orifice on another end; (v) feeding the crafting medium to enter one end of a flow passage of the second dispensing nozzle having a second discharge orifice on another end; (vi) heating the first dispensing nozzle to convert a leading portion of the filament therein to a flowable fluid; (vii) dispensing the flowable fluid through the first discharge orifice to an object-supporting platform; (viii) during the dispensing step, moving the dual printhead and the object-supporting platform relative to one another in a plane defined by first and second directions and in a third direction orthogonal to said plane to form the flowable fluid into a three-dimensional hollow pattern having a molding cavity shaped in accordance with a predetermined threedimensional object; (ix) during the dispensing step, operating the second dispensing nozzle for extruding the crafting medium on a layer by layer basis through the second discharge orifice onto the three-dimensional hollow pattern in order to gradually fill the molding cavity, thereby forming the predetermined three-dimensional object; and (x) removing the three-dimensional hollow pattern in order to release the predetermined three-dimensional object.The present invention further relates to an apparatus for performing the process.
