摘要

Processing settings have a direct influence on two important elements that affect the quality of a selective laser melting (SLM) component: build orientation and layer thickness. The recent work on layer-by-layer additive modelling before starting the SLM process has a number of advantages, including material, financial, and time savings. According to the experiment design, the fatigue strength, density, and hardness of the AlSi10Mg alloy were created dynamically in this main investigation using the SLM-AM. The L9 orthogonal array from the Taguchi technique was used in the experimental development process. It was discovered that 225 W, 500 mm/s scanning speed, 100-µm hatching distance, and 500° laser power produced the greatest results in terms of fatigue strength, density, and hardness. To ascertain the Taguchi loss of function for after-manufactured SLM components, such as part geometric inaccuracy discovered by the Artec 3D scanner, the samples were printed in compliance with ASTM standard samples in accordance with the experiment design. All process parameters were reached at 225 W, 500 mm/s, and 100 µm as T5, without a loss of function, for both wear and fatigue specimen. For the experimental density result, a high density value of 99.6% (2.66 g/cm3), a defect-free component, and a hardness of 126 ± 5 HV were attained. In order to ascertain mechanical properties utilising suitable production settings for aviation applications, this study will going forward concentrate on as-built and warmed conditions. At T5, there was 94 µm of low wear and 14.1 N of frictional force. Using the optimal process parameter (T5), which was found to be 150 J/mm3, the laser energy density was calculated.
