Rapid Prototyping Techniques (Layer Based Manufacturing Methods - LBMMs) give a possibility of producing highly complex geometrical parts directly from 3D-CAD data. At the beginning, LBMMs were used only for building prototypes from plastic materials for model visualizations and investigations of construction validity in early product development stages. Nowadays, LBMMs have transformed into additive technologies, capable of manufacturing objects from selected plastics and almost any metal (stainless steel, tool steel, titanium and its alloys, Co-Cr, aluminium alloys). For the metal technologies the objective is the capability to manufacture fully functional products (e.g. medical implants, inserts with conformal cooling channels for moulds) with customized mechanical properties. The paper will present results of research on one such technology – selective laser melting (SLM), in the Centre for Advanced Manufacturing Technologies at the Wroclaw University of Technology.
