The renowned academic journal Science published a research review paper titled "Material-Structure-Performance Integrated Laser-Metal Additive Manufacturing" on May 28, 2021. Nanjing University of Aeronautics and Astronautics, or NUAA, served as the first signature unit, while Professor Gu Dongdong from the College of Materials Science and Technology served as the first author and corresponding author.
High performance metal components are the cornerstone of modern industries such as aviation, aerospace, transportation, and energy, and the service performance of high-end equipment depends on the performance of the individual components.
The research proposes a holistic concept of material-structure-performance integrated additive manufacturing (MSPI-AM) to cope with the extensive challenges of AM. It defines MSPI-AM as a one-step AM production of an integral metallic component by integrating multimaterial layout and innovative structures, with an aim to proactively achieve the designed high performance and multifunctionality.
Driven by the performance or function to be realized, the MSPI-AM methodology enables the design of multiple materials, new structures, and corresponding printing processes in parallel and emphasizes their mutual compatibility, providing a systematic solution to the existing challenges for laser-metal AM.
