Recently, the collaborative research results between Addireen and Nanjing University of Aeronautics and Astronautics (NUAA) in the fields of metal additive manufacturing and advanced thermal management structures were officially published in the International Journal of Thermal Sciences.

As we enter 2025, global manufacturing is accelerating toward higher precision, efficiency, and intelligence. Laser technology is evolving rapidly and has become a key driver of advanced manufacturing in sectors such as new energy, consumer electronics, and the semiconductor industry. Among these innovations, high-power green pulsed fiber lasers are setting new benchmarks, offering excellent absorption at the 532nm wavelength for highly reflective materials such as copper and gold. With greater average output power, enhanced beam quality, and compact design, they are enabling breakthroughs in

Copper exhibits exceptional thermal and electrical conductivity, enabling its extensive application in sectors such as aerospace, new energy vehicles, and high performance computing. Despite its industrial significance, copper remains challenging to process efficiently and with high quality via additive manufacturing techniques. One critical consideration is the laser wavelength utilized during the printing process.

Additive Manufacturing (AM) is a process that builds 3D objects by depositing material layer by layer. It provides exceptional geometric flexibility, which is often difficult to achieve through traditional manufacturing methods. The aerospace industry was among the earliest adopters of AM, which has gradually been applied to the rapid production of precision components such as rocket combustion chambers, engine nozzles, turbine parts, and aircraft rudder.
