摘要： Improved apparatus and methods for forming a layer of material over a surface of a previously-formed cross-section of a three-dimensional object in anticipation of forming a next cross-section of the object out of the layer. A volume of material, including at least some excess material, is placed over the surface, and the excess material is swept off by placing the excess material in the predetermined path of a sweeping member, the path being substantially in a plane spaced from a working surface of material. The member may be directed to sweep the excess material away through a successive number of sweeps, which may vary for each cross-section, at least a velocity which may vary for each sweep. Additionally, the clearance between the member and the surface of the previous cross-section may vary for each sweep. A "winged" member is also provided, comprising two legs extending from a base, and a "Trident" embodiment is also provided, comprising three legs extending from a base.
摘要翻译：改进的用于在三维物体的预先形成的横截面的表面上形成材料层的装置和方法，以期将物体的下一个横截面形成在该层之外。将一定体积的材料（包括至少一些多余的材料）放置在表面上，并且通过将多余的材料放置在扫掠构件的预定路径中来清除多余的材料，该路径基本上处于与工作材料表面。该构件可以被引导以通过连续数量的扫描来扫过多余的材料，该扫描对于每个横截面可以变化，至少每个扫描可能变化的速度。此外，构件和前一横截面的表面之间的间隙可以针对每个扫掠而变化。还提供了一个“翼形”构件，其包括从基座延伸的两个腿部，并且还提供了“三叉戟”实施例，其包括从底座延伸的三个腿部。

摘要： Apparatus for and related methods of forming three-dimensional objects out of a building material, which is normally solid, but which is flowable when heated. In one embodiment, a support material is used to fill in portions of layers which are not to be solidified as part of the object, thus providing support to otherwise unsupported portions of other layers. Advantageously, the support material is also normally solid and flowable when heated, and has a lower melting point than the building material enabling the support material to later be removed without damaging the object. In an alternative embodiment this support material can be used to build a support such as a web support, or the like, for supporting an object surface from a second surface. In another alternative embodiment, such an apparatus is combined with a conventional stereolithographic apparatus to provide means for forming an object out of conventional stereolithographic materials, but utilizing a normally solid but thermally-flowable support material to provide support to the object, either on a layer-by layer basis, or by building supports such as web supports.
