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.

9812984曾本小额探索性研究拨款旨在证明一种新方法的可行性，即利用自由形状制造系统制造复杂的三维金属材料。本项目以平面层沉积技术为基础，构建了一个原型系统，包括一个配有可调喷嘴的平面射流发生器，一对用于压制、冷却和调平的辊，以及一个配有位置可控基板的沉积室。由平面射流发生器形成的具有理想宽度的薄片或层有助于最终的三维结构。平面层沉积方法改变了目前的自由曲面制造概念，从点对点成形到逐层沉积，从而大大提高了生产率。发电机坩埚的设计温度可达1000摄氏度。本项目将选择熔化温度相对较低的金属自由成形一个精度为0.2 mm的金属零件，以证明平面层沉积技术的概念和潜在能力。
