Abstract
Selective laser melting (SLM) is a key technology for direct forming of metal parts in 3D printing technology. SLM technology can realize the direct forming of parts with complex shape, high dimensional accuracy and excellent mechanical properties. It is especially suitable for rapid manufacturing of personalized and customized structures of aerospace difficult-to-machine parts. SLM forming process involves complex physical and chemical behavior of materials. Forming mechanism is quite different from traditional casting processes. The process parameters are complex and difficult to control. In this paper, a set of SLM forming process parameters suitable for Ti6Al4V alloy has been explored through the development of a SLM forming equipment of ESO M290 in Germany. The innovation of this product application design is the SLM printing design and process of minimal size dual-antenna, and the process method and design idea are universal. SLM forming technology based on Ti6Al4V alloy will be more and more widely used in aerospace field.
