The technologies of 3D modeling and rapid prototyping are beginning to be widely used by the biggest industries of the Brazilian jewelry sector. However, the reactivity of this sector affects the search for product design innovations. Seeking to understand how the introduction of these technologies and processes influence the process of jewelry design, this dissertation aims to evaluate the innovations that 3D modeling and rapid prototyping bring to the industries and the jewelry designers who uses these technologies. Through literature review and action-research - divided in interviews with professionals who had worked with the technologies for more than two years and an empirical research of the introduction of these technologies by the team of researchers from the project INOTEC in partnership with five designers from jewelry and related companies from Rio de Janeiro – this dissertation sought an understanding of the main advantages and disadvantages that the diffusion of these technologies can bring to the jewelry sector.
