Innovative Jewellery Manufacturing Process using 3D Printing (JewelPrint)

“该项目的目的是为贵金属3D打印制造珠宝（JewelPrint）进行技术经济可行性路线图。今天，英国珠宝行业价值60亿英镑，2017年实现了6%的增长。总之，珠宝制造业是英国经济的重要支柱。珠宝制造涉及一个具有挑战性的，漫长的，多阶段的，低效的复杂过程。它包括设计步骤，创建一个模具，反过来又用于制作蜡复制品，铸造珠宝，然后抛光/精加工。这些步骤中的大多数几十年来几乎没有改变。这些工艺有几个限制：铸造精度、孔隙/空隙、铸造和精加工中的高成本贵金属浪费。此外，与制造业相关的劳动力费用也很昂贵。珠宝制造业的最初迹象出现在约3000-5000年前的古埃及社区，在那里，他们更喜欢黄金的奢华，稀有性和可加工性。Jewelry与关键的社交场合有关，具有情感和情感价值，因为产品通常与出生，婚礼和周年纪念等关键生活事件有关。我们的项目JewelPrint将创造一种创新的3D打印技术，以生产高质量的零件，提高效率、分辨率、表面光洁度，减少翘曲和热应力，并打开珠宝制造中3D贵金属打印的市场。"

"The aim of this project is to conduct the techno-economic feasibility roadmap for the 3d-printing of precious metals to manufacture jewellery (JewelPrint).Today, the UK jewellery sector is worth £6bn and achieved 6% growth in 2017\. In summary, the jewellery manufacturing sector, is a key pillar of the UK economy.Jewellery manufacturing involves a challenging, lengthy, multi-stage, inefficient complex process. It includes design steps, creating a mould which in-turn is used to make wax reproductions, casting of the jewellery followed by polishing/finishing. Most of these steps have barely changed over decades. There are several limitations associated with these processes: accuracy of casting, porosity/voids, high-cost precious metal waste in casting and finishing. Further, there are costly labour fees associated with manufacturing.The first signs of established jewellery making was in Ancient Egypt communities, ~ 3000-5000 years ago, where they preferred the luxury, rarity, and workability of gold over other metals. Jewellery is associated with key social occasions, with emotional and sentimental value attached since products are often linked to key life events such as births, weddings and anniversaries. This association is unlikely to ever change.Our project, JewelPrint, will create an innovative 3-d printing technology to produce high quality parts with improved efficiency, resolution, surface-finish, reduced warpage and thermal stresses and open-up the market for 3d-precious metal printing in jewellery manufacture."
