专利汇可以提供A THREE-DIMENSIONAL IMAGING APPARATUS HAVING A COLOR MIXING CHANNEL专利检索,专利查询,专利分析的服务。并且The present invention relates to a three-dimensional imaging apparatus for modeling a colored three-dimensional object on a layer-by-layer basis in accordance with a computer aided design (CAD) image of the object. The apparatus includes a printhead unit comprising a melting chamber; a primary feeding channel arranged between a supply of primary modeling material in solid state, preferably in filament form, and the melting chamber; driving means to drive and regulate the flow of the primary modeling material through the primary feeding channel toward the melting chamber; secondary feeding channels each of which is arranged between a supply of colorant material in solid state, preferably in filament form, and a color mixing channel in connection with the melting chamber; driving means to drive and regulate the flow of the solid colorant materials in accordance with a predetermined computer generated coloring pattern to the color mixing channel; heating means arranged adjacent to the color mixing channel and the melting chamber for supplying heat energy inside the color mixing channel and the melting chamber for converting the primary modeling material and the colorant materials therein from a solid state to a flowable fluid state to obtain a colored modeling material; a dispensing nozzle through which the colored modeling material in flowable fluid state is conveyed from the melting chamber to an object supporting platform positioned at a predetermined distance from the dispensing nozzle and motion devices coupled to said platform and said nozzle for moving said nozzle and said platform relative to one another in a plane defined by first and second directions and in a third direction orthogonal to said plane to deposit said flowable fluid material into a three-dimensional object.,下面是A THREE-DIMENSIONAL IMAGING APPARATUS HAVING A COLOR MIXING CHANNEL专利的具体信息内容。
