Properties of Models Produced by Direct Selective Laser Melting Technology

Abstract:

The paper deals with evaluation of selected mechanical properties of tensile test specimens which were made from AlSi12 material by Direct Selective Laser Melting (DSLM) technology. Specimens were built in three various set-ups such as different angles towards building platform and various types of supporting structures in order to prove the influence of these parameters to mechanical properties of resulting product. The specimens were also subjected to material tests to reveal its inner structure, quality of a grain and chemical composition of the material. As a conclusion, the selection of the most suitable supporting structure and alignment of a model towards building platform are discussed. Mechanical parameters evaluated from tensile tests such as Young’s modulus (E), 0.2% proof stress (Re₀_,2) and tensile strength (Rm) are compared with values typical for the selected material AlSi12.
