專利摘要(中)
一種新穎的快速3D原型/製造技術，其特點在於使用一異向雙出口佈料頭，包含兩個分佈方向不同的佈料出口，分別可以塗佈立式或臥式的帶狀材料，增進組成3D製件的幾何彈性；佈料路徑可採用彈性變向式積層方式，使材料能沿3D製件的表面切線方向成形；並突破現行的細線薄層的佈料方法，也可採取一厚層成形方法逐層佈料，以一微分模具改變出料曲率或以一整形裝置修整已塗佈的材料，以消除積層階梯問題，使表面光滑度更好，並加快3D成形速度。

專利摘要(英)
A rapid prototyping and production system features a dispensing head capable of dispensing material from two connected but basically perpendicular exits, one for dispensing material in erected positions and one for dispensing material in horizontal positions. In general, the dispensing head of this invention comprises adjustable exit capable of changing cross-sectional area by a factor of at least 10 to 200 to accommodate variation of required geometric feature size and to increase build rate. Further, this invention includes a shaping tool for reshaping solidified dispensed material to improve curvature and surface finish. Still further, this invention includes a Thick-layer Building procedure, which builds a 3D object by repeatedly alternating a dispensing step to dispense a thick layer of material and a shaping step, using a shaping tool, to reshape the layer.
