Description

Selective laser melting technology (Powder Bed Fusion - " material melting in a pre-formed layer" according to ASTM classification) is one of the most promising additive manufacturing technologies because it has a number of fundamental advantages such as zero-waste, versatility, the ability to manufacture complex-shape parts with high accuracy that are not inferior to and sometimes exceeding in their physical and mechanical characteristics parts obtained by traditional shaping. Additive technologies allow the use of a wide range of powder materials, varying the composition of the applied material directly in the application process according to the functional purpose of the inner and outer parts of the model. The use of laser additive technologies should reduce the manufacturing time and cost of complex parts in single and small-scale production. Combining the idea of composite materials and high precision additive manufacturing technologies in the processes of three dimensional product shaping is an urgent scientific and technical task.

This work demonstrates the prospects for using selective laser melting technology for manufacturing specific parts from aluminum-based alloys. This area is especially in demand in the aerospace and automotive industries. The influence of the selective laser melting parameters on structure formation of aluminum-based alloys was studied using the methods of optical analysis, X-ray diffraction and X-ray spectroscopy analysis. According to the obtained results of mechanical tests of samples produced in different directions, differences in strength characteristics depending on the direction were revealed. The results of the performed experiments demonstrate the rational regimes of selective laser melting technology for aluminum-based alloys, depending on the produced direction. In this work recommendations are provided on the technological process of selective laser melting for manufacturing aluminum alloy products with a high complex of physical and mechanical properties.
