The jewellery industry is facing significant market and customer challenges because it is still centred on traditional fabrication methods based on manual hand work. Except for a few international companies, most jewellery manufacturers do not apply advanced digital and/or physical technologies. The inclusion of new production methods, including 3D CAD and additive manufacturing processes, is one of the ways to overcome these challenges and limitations and increase its market and customer satisfaction. In this paper, advanced digital manufacturing technologies will be applied to design jewellery based on cultural heritage artefacts as the case of the Portuguese guitar. After that this are modelled as pendant, earrings, and ring. 3D modelling is an indispensable tool to design novel complex concept and through 3D printing the production is realized in a short time with least material waste.
