Title Support Structure Design for Titanium Alloy Spiral Case in Additive Manufacturing
Abstract
Additive manufacturing technology (3D printing) is a kind of new manufacturing technology, different from the traditional processing way has the extensive attention of related industries. Support structure design is in the process of forming metal parts need to focus on a key technique, design of supporting structure is related to the processing efficiency, the forming quality of parts and material consumption. Parts of morphology characteristic determines the support design principle, especially for complex shaped structure, thin wall structure, pipeline structure, in order to ensure that increase the success rate of the material manufacture on supporting type selection, support structure optimization problem needs to be addressed. This article is in serious study and research, on the basis of predecessors' achievements, according to the structural characteristics of spiral case structure of the form, use Magics ,established the optimal forming direction at the same time, for the support structure of the optimal design of this product.

1.1 增材制造技术概述
增材制造技术(Additive Manufacturing，AM)[1]是一种由CAD模型直接驱动，将材料逐层或逐点堆积出实体零件的技术总称，它是制造业领域正在迅速发展的一项新兴技术，被称为“具有工业革命意义的制造技术”。增材制造的理念区别于传统的“去除型”制造，与传统材料去除——切削加工技术相比，是一种“自下而上、分层制造、逐层叠加”的加法制造思想，俗称“3D打印”技术。
