摘要： A rapid prototyping and manufacturing (e.g. stereolithography) method and apparatus for making three-dimensional objects on a layer by layer basis by selectively exposing layers of material to prescribed stimulation, using a beam having a first smaller diameter and a beam having a second larger diameter, to form laminae of the object. The power of the smaller beam is typically lower than the power of the larger beam. Object formation is controlled by data representing portions of the layers to be exposed with the larger beam (large spot portions) and those portions to be exposed with the smaller beam (small spot portions). In a preferred embodiment, portions exposed with the larger beam are formed first, for a given layer. Portions are exposed with the small beam next. Thereafter the entire perimeter of the laminae is traced using the small beam. Data manipulation techniques are used to identify which portions may be formed with the large beam to decrease exposure time and which should be formed with the small beam to maintain accuracy of the lamina being formed. More than two beam diameters may be used.

摘要： An illumination system includes optics capable of adjusting the size of a beam of light and adjusting the focus of the beam of light. Spot size control optics adjusts the lateral extent of the beam of light. Light from the spot size control optics passes to focus control optics that control the focus of the beam of light. The beam of light focussed by the focus control optics has a first focus position for a first lateral component of the beam of light and a second focus position for a second lateral component of the beam of light, the first and second lateral components being perpendicular. The focus control optics adjust the first focus position to a greater axial extent than the second focus position. Actuators adjust the focus control optics.

摘要： An illumination system includes optics capable of adjusting the size of a beam of light and adjusting the focus of the beam of light. Spot size control optics adjusts the overall size of the beam of light and separately adjusts the ellipticity of the beam, primarily in one dimension. Light from the spot size control optics passes to focus control optics that control the overall focus of the beam of light and adjust the astigmatism of the beam by altering the focus position of the beam of light in one dimension. The laser system, the spot size control optics and the focus control optics are within an enclosure. Actuators under remote control from outside of the enclosure adjust both of the spot size control optics and focus control optics in the thermal environment of the illumination system.
