Abstract: A rapid prototyping and manufacturing (e.g. stereolithography) method and apparatus for producing three-dimensional objects by selectively subjecting a liquid or other fluid-like material to a beam of prescribed stimulation. In a preferred embodiment a source of prescribed stimulation is controlled to reduce or inhibit the production of the prescribed stimulation during at least some periods when the prescribed stimulation is not needed to expose the material. In another preferred embodiment, the source of stimulation is controlled to vary the quantity of prescribed stimulation that is produced and allowed to reach the material. In a additional preferred embodiment control of laser output occurs based on a combination of supplying a regulated amount of voltage to an AOM in conjunction with temporary sensing of laser power and a known desired power to attain. In a further preferred embodiment, a quantity of prescribed stimulation may be set by consideration of desired solidification depths to be used, beam profile characteristics, material properties, and scanning speed limitations for different data types. In a still further preferred embodiment, a transition between selected consecutive exposure vectors is performed by scanning one or more interposed non-exposure vectors with the beam inhibited from reaching the building material.

Abstract: Techniques are described for controlling jobs in a Selective Deposition Modeling (SDM) system. A client computer system (40) can connect directly to a Selective Deposition Modeling system (46) to work with a job queue (60-80) located at the Selective Deposition Modeling system. Jobs in the job queue may be previewed in three-dimensional form (54, 56). Moreover, the jobs in the job queue may be manipulated to move the jobs to different positions in the job queue or to delete a job. Additionally, multiple jobs may be automatically combined (90, 92) to generate a single build process.

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 method of manufacturing a part involving steps of using data derived from a slicing programme to control a manufacturing means that makes coatings that are the cross sectional slices of the required part which also contain right angles or some other edge feature that is the male or female counterpart to a feature made by a base, and, placing the coatings in the base and vibrating them, so that they settle in register onto the base's feature. In addition it is necessary the coating may be bonded together when they have been registered or as each coating is registered.

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.
