Abstract
The results previously obtained with gold alloys for selective laser melting (SLM) underlined the key role not only of process parameters but also of powder chemical composition for producing quality precious metal jewellery. This paper illustrates the effect of some selected chemical elements to improve laser radiation absorption and to favour the melting of metallic particles. In addition, the impact of the structure and morphology of the supports was examined in order to optimize their density and maintain an adequate thermal dissipation of laser energy.| File | Dimensione | Formato | |
