Jewellery from Hong Kong is mainly hand-craved especially for the gem-setting and assembling processes. As 3D printing technology matures, many jewellery brands have begun to apply this advanced technology to make jewellery moulds and parts. Today, 20% to 30% of the production of jewellery rely on 3D printing and the percentage will increase in the future. Not only can it save time and labour costs, but it also realise more complicated and detailed designs. To meet the growing demand for personalised jewellery products, 3D printing can manufacture customised designs and make each item unique and more valuable.
