Abstract
Advanced forming manufacturing technology is developing toward high efficiency, low energy consumption, green environmental protection, and precision, which promotes the development trend of high-strength and lightweight metal structural materials. This study employs the selective laser melting technology to form a periodic spatial lattice structure model with optimal load-bearing capacity by using TC4 as the experimental material to prepare experimental samples. Using orthogonal tests, loading tests, and metallographic structure analysis methods, the influence of different combinations of laser power, scanning speed, and support form on the mechanical properties of different weight reduction scale models is explored. When the SLM laser power is 290 W, the scanning speed is 900 mm/s, and the volume support is 3, the process combination has the best load-bearing capacity when forming periodic spatial mesh structure models with different weight reduction ratios (30 %, 50 % and 70 %).
期刊介绍：
The aim of the Journal of Mechanical Science and Technology is to provide an international forum for the publication and dissemination of original work that contributes to the understanding of the main and related disciplines of mechanical engineering, either empirical or theoretical. The Journal covers the whole spectrum of mechanical engineering, which includes, but is not limited to, Materials and Design Engineering, Production Engineering and Fusion Technology, Dynamics, Vibration and Control, Thermal Engineering and Fluids Engineering.
Manuscripts may fall into several categories including full articles, solicited reviews or commentary, and unsolicited reviews or commentary related to the core of mechanical engineering.
