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.

In the rapid development of New Energy Vehicles (NEVs), the IGBT power module plays a pivotal role in the energy conversion of electric drive systems, with its reliability directly linked to vehicle safety and performance. However, both industry experience and academic research repeatedly point out that the true "invisible killer" of power modules is not electrical issues, but thermal stress fatigue induced by high temperatures and temperature cycling. This thermal fatigue eventually manifests as failure modes like solder layer cracking and bond wire liftoff, which are the root causes of short

By implementing green laser PBF printing technology, both pure copper and copper alloy can be used for induction coil 3D printing to replace traditional machining and brazing. The coils, manufactured directly from digital models in complex shape, reduce production lead time by two-thirds while ensuring dimensional accuracy and material integrity. The laser sintered copper matrix enhances structural rigidity, leading to a longer service life and superior resistance to thermal fatigue compared to brazed counterparts.

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
