Title: Developing Ti Jewelry Through Additive Manufacturing and Conversion Technologies
Issue Date: 2011
Abstract: Nowadays there are an enormous variety of titanium (Ti) jewelry artifacts. These products have ahigh specific strength, are corrosion resistant, promote a warm feeling to the human touch and are easily surfacemodified by temperature or anodization to acquire a sophisticated aesthetic colour. Ti is more durable than goldor platinum, has a lower price and is a fashion material due to the successful use in challengeable applications.This paper describes the importance of using additive manufacturing and conversion processes to developinnovative jewelry titanium artifacts. Combining 3D modelling, stereolithography, conversion technologies withsilicone and low melting point metallic molds and precision casting in ceramic shells molds in controlledatmosphere, we were able to manufacture complex shapes with shiny thin sections, that after an adequate heattreatment exhibit a variety of attractive colors that are more difficult and expensive to obtain with existingtechnology for manufacturing jewelry products (metal forming and machining).
