摘要： A method and apparatus for forming a three-dimensional article includes dispensing build material and thermally normalizing predetermined portions thereof at predetermined intervals during construction of the article. The thermal energy may be provided by a heated body (87) advanced adjacent to or in contact with the surface portions (212). Thermal energy may also be supplied by a radiation source. The thermal normalization may be performed after a predetermined number of successive layers are dispensed. Related methods are also disclosed.

摘要： A three-dimensional article making apparatus includes a processor operatively connected to a dispenser and positioner for constructing the article based upon the article defining data. The processor operates the dispenser to construct an enlarged surface of a first article portion to thereby define an enhanced target landing point area for dispensed droplets of build material for constructing a second article portion adjacent the first article portion. The enhanced target landing point area permits a slight misalignment or error that may occur between adjacent article portions. The processor also avoids shadowing during construction of the article by operating the dispenser to construct third and fourth adjacent article portions so that a dispensing path for constructing the third article portion is unobstructed by a previously constructed part of the fourth article portion. Related methods are also disclosed.

摘要： A three-dimensional article making apparatus includes a build material dispenser (34) positioned adjacent a platform for ejecting a plurality of droplets of build material; and dispenser positioners for relatively positioning the dispenser in five degrees of freedom with respect to the platform. Accordingly, the dispenser may be rotated and flipped to permit construction of a cantilevered portion of an article without requiring support material. The dispenser positioners include a Z-direction positioner for positioning the dispenser vertically relative to the platform, and X-Y positioner for positioning the dispenser in an X-Y planar direction relative to the platform, a flip angle positioner for rotatably positioning the dispenser relative to a generally horizontal axis, and a phi angle positioner for rotatably positioning the dispenser relative to a generally vertical axis. A processor is operatively connected to the dispenser and the dispenser positioners for advancing the dispenser along a predetermined path of travel while operating or firing the dispenser to construct the three-dimensional article in successive layers or portions based upon the article defining data. Method aspects of the invention are also disclosed.
摘要翻译：一种三维制品设备包括：一个邻近平台定位的构建材料分配器（34），用于喷射多个构建材料液滴; 以及分配器定位器，用于将分配器相对于平台相对地定位在五个自由度。因此，分配器可以旋转和翻转以允许在不需要支撑材料的情况下构造制品的悬臂部分。分配器定位器包括用于相对于平台垂直定位分配器的Z方向定位器和用于将分配器相对于平台相对于XY平面方向定位的XY定位器，用于将分配器相对于大致水平的可旋转定位的翻转角定位器以及用于相对于大致垂直的轴线可旋转地定位分配器的phi角度定位器。处理器可操作地连接到分配器和分配器定位器，用于沿着预定的行进路径推进分配器，同时操作或点燃分配器，以基于定义数据的物品构建连续层或部分的三维制品。还公开了本发明的方法方面。
