Shenzhen Addireen Technologies showcased advancements in green-laser LPBF systems for copper 3D printing at TCT Asia 2026 in Shanghai. The company demonstrated hardware optimized for high-reflectivity materials, specifically targeting the thermal management and electrical conductivity requirements of the EV and power electronics sectors. By utilizing green-wavelength lasers, the system effectively overcomes the absorption limitations inherent in standard infrared fiber lasers when processing pure copper, resulting in higher density parts and improved build consistency.

Copper additive manufacturing remains a critical bottleneck for high-performance thermal applications, as traditional infrared lasers often struggle with the high reflectivity of the material. Shenzhen Addireen Technologies is positioning its hardware to compete with established international players like Trumpf and EOS, which have previously dominated the green-laser metal AM segment. This development highlights the broader trend of Chinese manufacturers moving beyond basic machine assembly toward specialized, application-specific hardware solutions that address complex material challenges.

For industrial users, the focus should remain on the repeatability of these green-laser systems in continuous production environments rather than just peak build rates. Potential adopters must validate the mechanical properties and electrical performance of the printed copper components against existing casting or CNC machining benchmarks to justify the transition to additive workflows.
