摘要： 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 an 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.

摘要： A three-dimensional printer adapted to construct three dimensional objects is disclosed. In an exemplary embodiment, the printer includes a first surface adapted to receive a bulk layer of sinterable powder, a polymer such as nylon powder; a radiant energy source, e.g., an incoherent heat source adapted to focus the heat energy to sinter an image from the layer of sinterable powder; and a transfer mechanism adapted to transfer or print the sintered image from the first surface to the object being assembled while fusing the sintered image to the object being assembled. The transfer mechanism is preferably adapted to simultaneously deposit and fuse the sintered image to the object being assembled. The process of generating an image and transferring it to the object being assembled is repeated for each cross section until the assembled object is completed.

摘要： A baseball pitching machine is disclosed preferably employing a counterrotating wheel type baseball launch subsystem pitching a series of baseballs and a computer controlled system for selecting the type and percentage of pitches, pitcher and batter characteristics, strike zone areas and other parameters to provide a meaningful batting training session. The pitching machine includes a ball transport subsystem including a carousel for receiving and transporting baseballs in sequence to a position adjacent the counter rotating wheels. While being transported, each baseball stops at seam orienting stations where seam rotators rotate the baseball to provide a commanded seam orientation for the particular pitch selected. The baseball is oriented by the ball orienter for insertion in the launch subsystem. A computer allows the selection by the operator of a variety of pitches, random or selected order. The computer has memory capability for storing pitches corresponding to any pitcher's typical pitch pattern and the system includes video, audio and data recording to record each batting session. An alignment system is included utilizing a laser light source. A remote control is also provided for the batter or his coach. A manual baseball inserter is disclosed for use with other pitching machines.
