    • Methods and apparatus for fabricating structures, extrusion units, and structures fabricated using such methods and apparatus are disclosed. The apparatus may include a support configured for rotation about a central axis, a carriage that may move along the support when the support rotates about the central axis such that the carriage may move along a first spiral path about the central axis, and an extrusion unit that may be supported by the carriage and may move along a second spiral path as the carriage moves along the first spiral path. The extrusion units may be configured to extrude a strip of material through an extrusion die as the extrusion unit moves along a previously extruded strip of material such that the extruded strip may be fused onto the previously extruded strip as the extruded and previously extruded strips pass the extrusion die.
    • 公开了使用这种方法和装置制造结构,挤出单元和结构的方法和装置。 该装置可以包括构造成用于围绕中心轴线旋转的支撑件,当支撑件围绕中心轴线旋转时可以沿支撑件移动的滑架,使得滑架可以围绕中心轴线沿着第一螺旋路径移动,并且挤出单元 其可以由滑架支撑并且随着滑架沿着第一螺旋路径移动时可以沿着第二螺旋路径移动。 挤压单元可以被配置为当挤出单元沿着先前挤出的材料条移动时挤出一条材料条,使得当挤出的和预先挤出的带通过时,挤出的条可以被熔合到先前挤出的条上 挤出模具。
