基于3D打印和失蜡铸造技术的首饰活动结构创新设计(英文)

3D打印技术为现代设计与生产带来了广泛的变革。全球各国政府、科研院所和企业都已大力推动与发展3D打印技术及其在各行业中的应用。在珠宝行业,运用喷蜡3D打印和失蜡铸造相结合的模式已广泛地作为一种创新的生产方式,在复杂与独特的首饰制造方面发展相对成熟。然而,3D打印技术所拥有的成形局限小、成形精度高的优势并没有得到充分的运用。其主要原因是把3D打印技术用于代替传统的手工起版,而没有将其3D打印技术成形局限小、成形精度高的优势运用于首饰的创新设计。本文基于3D打印技术及其成形工艺提出首饰活动结构的设计思路与原则。从首饰制造工艺的角度对球套活动结构、内悬挂活动结构、多螺旋式活动结构和轴活动结构展开3D打印首饰设计与应用研究。

Innovative Movable Structure Design for Jewelry Application Based on Integrated 3D Printing and Lost-Wax Casting Technology

3D printing technology has brought unprecedent innovation in modern design and production.Governments, research institutions and enterprises in many countries, have put great effort in developing 3D printing technology and its application in various industries.In jewelry industry, the 3D wax printing technology integrated with lost-wax casting method has been applied widely as an innovative production approach, becoming relatively mature method for making complex and novel jewelry.However, the advantages of 3D printing technology such as less molding geometry restriction and high molding geometry accuracy have not fully exploited yet.As 3D printing technology is primarily used for substituting traditional manual molding method, its molding geometry advantage and accuracy is seldom utilized for innovative jewelry design.In this paper, the design concept and principle for jewelry movable structure were proposed based on 3D printing technology and related lost-wax molding technique.3D printing design and application studies were conducted for ball sleeve movable structure, internal suspension movable structure, multi-spiral movable structure and axial movable structure in jewelry fabrication.
