9812984 Tseng这个探索性研究的小补助金是为了证明一种通过自由成形制造系统生产复杂三维形状的金属材料的新方法的可行性。该项目涉及建立一个原型系统，基于平面层沉积技术，由一个平面射流发生器配备可调喷嘴，对辊的压力，冷却和平整，和一个沉积室配备了一个位置可控的基板。由平面射流发生器形成的具有期望宽度的片或层有助于最终的三维结构。 平面层沉积方法将当前的自由成形制造概念从点对点成形改变为逐层沉积，并且因此将显著地提高生产率。发生器坩埚的设计温度可达1000摄氏度。一个相对较低的熔化温度的金属将被选择为自由成型的金属零件，0.2毫米的精度在这个项目中，以证明平面层沉积技术的概念和潜在的能力。

9812984 Tseng This Small Grant for Exploratory Research is to demonstrate the feasibility of a novel means of producing complex three dimensional shapes of metallic materials by a freeform fabrication system. This project involves building a prototype system, based on the planar layer deposition technology and consists of a planar jet generator equipped with adjustable nozzles, pairs of rollers for pressing, cooling, and leveling, and a deposition chamber equipped with a position-controllable substrate. A sheet or layer with a desirable width formed by the planar jet generator contributes toward the final three-dimensional structure. The planar layer deposition approach changes the current freeform fabrication concept from point-to-point forming to layer-by-layer deposition and as a result, will dramatically improve the production rate. The generator crucible is designed to achieve temperatures up to 1000 degrees centigrade. A relatively low melting temperature metal will be selected for freeforming a metal part with a 0.2-mm accuracy during this project to prove the concept and potential capability of the planar layer deposition technology.
