Abstract
Laser selective melting (SLM) is a manufacturing process that uses laser to melt metal powder layer by layer to form parts, which can realize the integrated manufacturing of complex parts. In this paper, SLM technology and topology optimization technology are combined to carry out the integrated design of the aviation aluminum alloy support . After optimization, the weight of the support is reduced by 24%, the maximum displacement is reduced by 82%, and the maximum stress is reduced by 65%. The process simulation analysis of the whole SLM forming process is carried out by using Simufact Additive software. On this basis, AlSi10Mg powder is selected for laser selective melting of the support, The forming of the whole structure meets the expectation, is in good agreement with the process simulation results, and there is no visible cracking failure.
