Title Basic research of 3D printing used in fuze micro components
Abstract
The most advanced science and technology were used to develop weapons for the war is cruel. The performance of fuze is getting higher and higher， but the design space of fuze is getting smaller and smaller. 3D printing is a hot new manufacturing technology in recent years. It can accumulate any complicated curved surface which means that more sophisticated technology can be realized in design. This characteristic may bring better mechanical performance and further reduce the volume of fuze.
3D printing process is introduced， and its applicability for fuze is discussed. A micro part of fuze is designed and processed. Thus the effect of 3D printing on the design of the micro component of fuze is discussed. The existing results of the micro machining technologies are studied and then drawn on fuze design and three-dimensional printing application. Finally the main works are summarized，and the focus of the study in the future is put forward.

1.1 本文研究背景及意义
引信是武器系统发挥终端效应的最终执行装置，其作用成败直接决定了武器系统与目标对抗的成败。因此引信技术在世界各国都得到了重视。目前引信向着小型化、多品种的方向发展，零件的尺寸减小，对功能的要求提高，这时用传统的加工方式制造起来就会比较困难。尤其是对于引信中许多的微小构件，为了适合传统加工方式，设计上往往会存在许多局限性。
