Jewellery design represents an area where artistic and handcraft approaches coexist with an industrial base. In recent years, large improvements have been made in those fields of jewellery design that use either non-noble or semi-noble metals. Among semi-noble metals, titanium stands out, giving the perception of a technical, advanced, and precious material. The peculiarity of titanium that makes this metal special for design applications is linked to its ability to be colored with electrochemical treatments. This research activity is focused on the application of a laser melting technique and the prototyping of titanium jewels with original design. This paper examines finishing techniques and the application of iridescent surface colour by anodic oxidation. It will build on experimental evidence tests in the aboratory linked with jewellery design concepts. Engineering processes, such as rapid prototyping, mechanical finishing, and electrochemical processes have been successfully implemented in jewellery design.

Prof. Barbara Del Curto

Associate Professor, Dipartimento di Chimica, Materiali e Ingegneria Chimica, Politecnico di Milano, Milano, Italy

Barbara Del Curto graduated in industrial design at Politecnico di Milano (Italy) in March 2000 and she earned her Ph.D. cum laude in materials engineering at Politecnico di Milano (Italy) in May 2004. She worked as post-doctoral researcher at Dipartimento di Chimica, Materiali e Ingegneria Chimica “Giulio Natta” Politecnico di Milano (Italy) from April 2004 to December 2004. Since January 2005, she has been an assistant professor at Politecnico di Milano, and in November 2010, she became an associate professor. Her scientific research has been devoted to many themes concerning traditional, functional, and smart materials for design and their expressive-sensorial dimension. Some of these topics are included in research projects funded by both private and public organizations. She has been involved as active scientific member, but also in the management, of several national research projects, funded by both private and public organizations. Her teaching activity is related to industrial design. She started her teaching activity in 2001 at Politecnico di Milano where, since 2005, she has been tenured for an academic course concerning properties of materials in design degree courses. Since March 2000, she has coordinated Materiali & Design, a didactical laboratory at the design school of Politecnico di Milano. She is the author of international journal publications and communications to national and international conferences.

Dr. Paola Garbagnoli

PhD Student, Dipartimento di Chimica, Materiali e Ingegneria Chimica “Giulio Natta”, Politecnico di Milano, Milano, Italy

Garbagnoli was born in Varese, Italy, on April 22nd, 1985. She earned her bachelor’s degree in product design at Politecnico di Milano (Italy) on July 2007, and she acquired her master’s degree in design and engineering at Politecnico di Milano in May 2010, cum laude. She worked as product designer in Italy and in Sweden (Stockholm). She is a PhD student in design at Politecnico di Milano and research fellow at the department of chemistry, materials and chemical engineering at Politecnico di Milano. Her research activity is related with themes concerning smart materials and their applications in design.

Valeria Masconale

Dipartimento di Chimica, Materiali e Ingegneria Chimica "Giulio Natta", Politecnico di Milano, Milano, Italy

Maria Vittoria Diamanti graduated cum laude in materials engineering at Politecnico di Milano (Italy) in 2005 and completed a PhD in materials engineering in the same university in 2009. In 2011, she became an assistant professor in Politecnico di Milano’s department of chemistry, materials, and chemical engineering. Her research interests explore the production of titanium dioxide films on titanium and the tuning of their properties as a function of the production method; the study of photoactive materials for wastewaters treatment and air quality improvement and as a complement to building technologies; and the study of localized corrosion phenomena on active-passive metals. During her PhD, she spent 6 months at Massachusetts Institute of Technology (Cambridge, MA) as visiting student, with a Roberto Rocca Fellowship. She is also collaborating with Masdar Institute of Science and Technology (Abu Dhabi, UAE) on a project related to the study of surface properties of titanium dioxide powders.

Masconale was born in Verona (Italy) in 1981, and earned a degree in industrial design for fashion from the Politecnico di Milano. Research fellow at the department of chemistry, materials and chemical engineering at Politecnico di Milano, she works with moulding and finishing techniques for the fashion industry.

Prof. MariaPia Pedeferri

Associate Professor, Dipartimento di Chimica, Materiali e Ingegneria Chimica, Politecnico di Milano, Milano, Italy

MariaPia Pedeferri graduated cum laude in chemical engineering at the Politecnico di Milano (Italy) in 1995, and she finished her PhD in chemical engineering three years later, almost entirely spent at the ETH in Zurich. In 1998, MP. Pedeferri joined the group of Prof. A. Cigada when she became an assistant professor in 2001, and in 2006, she became an associate professor of materials science and technology at the department of chemistry, materials, and chemical engineering at Politecnico di Milano, where she currently carries out her research and teaching activities. Her scientific research concerns the study of the degradation and protection of metallic materials and surface treatments of titanium with an emphasis on functional and aesthetic properties of this metal. She is the author of 70 papers in peer-reviewed journals, book chapters, three Italian patents, and she has more than 100 oral/poster communications at International and National Congresses. Since 2008, she has been a member of the Scientific Committee of NanoSurfaces, a Politecnico di Milano spin-off. She is/was involved in several projects for innovative materials development and technological transfer.
