Abstract: Tool having a molding surface is formed from a flowable material (e.g., powder material) wherein the shape of molding surface is formed from a molding process using a master pattern having a surface with a shape substantially the same as the shape of the molding surface to be formed. The tool has at least one thermal control element located within it and spaced from the molding surface where a component used in forming the thermal control element is located within the flowable material prior to solidifying the material. The powder material is preferably a mixture of metals. The thermal control elements include fluid flow paths, heating elements, temperature sensors, and the like.

Abstract: A three-dimensional object is formed by selectively depositing successive layers (14) of build material from a print-head (9) having a plurality of orifices or nozzles (10(1)-10(96)), such as an ink-jet type of print-head. The print-head (9) is moved (X-Y control) relative to a support platform (15) in a series of scans in the X-direction offset from one another in the Y-direction and possibly overlapping. The orifices (10(1)-10(96)) extend transversely of the scan X-direction and may be set at an angle (α) to it to control the resolution perpendicular to the scan direction. The platform (15) is movable relative to the print-head in the Z-direction for forming each successive layer (14). The build material is a flowable material and may be a radiation-curable material, such as an ultra-violet curable photo-polymer. The data according to which each layer is formed may be manipulated according to a selected build style to determine the selective activation of the print-head orifices.
