メタルジェットによる三次元構造体の造形(第2報)

メタルドットの結合力の測定

抄録

In recent years, various micro machining processes have been developed to meet the demands for micro machines. In this study, the authors developed a method to form micro functional parts by a metal jet. A thin layer is, first formed by molten metal jet ejected through a nozzle and a second layer is formed on the first layer. The repetition of this process produces the 3-dimensional structures. In this paper, new modeling system that can make 3-dimensional structure from 3-D CAD data is demonstrated. Various 3-D and 2-D models made by this system are also presented. Further, in order to determine the mechanical properties of micro structures, using metal jet, micro tensile and micro shearing test were conducted and the connecting strength between two metal drops was measured. Experimental results show the connecting strength between drops has strong unisotropy.
