Eplus3D unveils meter-scale copper Additive Manufacturing with red-laser technology
March 24, 2025
Eplus3D, located in Hangzhou, China, showcased several examples of meter-scale copper alloy parts at the recent TCT Asia 2025 exhibition in Shanghai, China. Reported to be a breakthrough in metal Additive Manufacturing technology, the company stated that the parts on display were built without the need for any hardware upgrades.
Copper has traditionally posed a challenge in Additive Manufacturing due to its high reflectivity and low energy absorption. Conventional red lasers often struggle to fully melt copper powder, which can result in issues such as unmelted particles, voids, cracks, and inconsistent layer bonding. Furthermore, copper’s excellent thermal conductivity leads to rapid heat dissipation, causing thermal stress, warping, and potential part failure.
Eplus3D’s advanced red-laser technology is said to overcome these challenges. On display was a φ1030×175 mm CuCrZr impeller produced on the company’s EP-M1250 metal Powder Bed Fusion (PBF-LB) AM machine. This component boasts an impressive 99.97% density and retains copper’s exceptional thermal conductivity-critical metrics for applications in aerospace thermal management systems.
“This latest technological breakthrough ensures the stability and long-cycle reliability of meter-scale copper parts,” the company stated. “Delivering unparalleled thermal and electrical conductivity for industries such as aerospace, automotive, and electronics.”
