Tunable Properties

Laser based powder bed fusion (LBPF) or selective laser melting (SLM) is making a leap march towards fabricating novel materials with improved functionalities. An attempt has been made here to fabricate hard quasicrystalline composites via SLM, which demonstrates that the process parameters can be used to vary the phases in the composites. The mechanical properties of the composite depend on their constituents and hence can be varied by varying the process parameters. The results show that SLM not only produces parts with improved functionalities and complex shape but also leads to defined phases and tunable properties.

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.

Low Porosity

Additive manufacturing (AM) technologies make it possible to produce complex shape metallic objects from powder feedstock. AlSi12 alloy is one of the most widely used materials in selective laser melting (SLM). The large number of technological parameters involved complicate the selection of an SLM mode for obtaining a product with the required structure. The goal of this research was to determine the mode which ensures the material’s low porosity. Nine specimens were fabricated by using different SLM process parameters. The fabricated specimens have different microstructures. The lowest porosity that was achieved is about 0.5%.
