    摘要: A method to form laterally supported features of a three-dimensional object by sequentially extruding the adjacent beads of a flowable and thermally solidifiable material. The feature comprises a series of adjacent and laterally offset beads, with at least a part of the laterally supported feature covering a vertically unsupported region. The method comprising the steps of vertically laminating a hub bead (34) over the vertically supported region (90), allowing the hub bead (34) to cool, laterally laminating a shelf bead (92) to the solidified hub bead (34), and repeatedly laminating additional shelf beads (94, 96, etc.) until the laterally supported feature is complete.

    摘要: Data corresponding to a desired shape of a prototype is transmitted to a rapid prototyping system. The system calculates (110) a sequence for extruding flowable material that thermally solidifies so as to create a desired geometric shape. A heated flowable modeling material is then sequentially extruded (112) at its deposition temperature into a build environment that maintains the volume in the vicinity of the newly deposited material in a deposition temperature window between the material's solidification temperature and its creep temperature. Subsequently the newly extruded material is gradually cooled (114) below its solidification temperature, while maintaining temperature gradients in the geometric shape below a maximum value set by the desired part's geometric accuracy.
