Innovative Technology Set to Revolutionize Industries
Eplus3D, a leading 3D printing technology company in Hangzhou, China, has unveiled a breakthrough in copper Additive Manufacturing. At the TCT Asia 2025 exhibition in Shanghai, the company showcased meter-scale copper alloy parts produced with its advanced red-laser technology. This breakthrough is set to revolutionize industries such as aerospace, automotive, and electronics.
Tackling Traditional Copper AM Challenges
Copper has traditionally been challenging for Additive Manufacturing due to its high reflectivity and low energy absorption. Conventional red lasers struggle to melt copper powder fully, resulting in problems like unmelted particles, voids, cracks, and weak bonding. Additionally, copper’s high thermal conductivity causes rapid heat dissipation, leading to thermal stress, warping, and part failure.
However, Eplus3D’s cutting-edge red-laser technology solves these issues effectively. The company demonstrated a φ1030×175 mm CuCrZr impeller produced on the EP-M1250 metal Powder Bed Fusion (PBF-LB) machine. This part achieved 99.97% density and retained copper’s excellent thermal conductivity, making it ideal for aerospace thermal management systems and other high-performance applications.
A Technological Breakthrough for Greater Performance
Eplus3D’s red-laser technology guarantees the stability and long-cycle reliability of meter-scale copper parts. The technology delivers exceptional thermal and electrical conductivity, essential for industries such as aerospace, automotive, and electronics. Furthermore, it opens up new opportunities for using copper in Additive Manufacturing without the need for hardware upgrades.
By overcoming the challenges of traditional copper processing, this new technology will significantly scale Additive Manufacturing for larger copper parts. As a result, the potential application of copper in 3D printing is set to expand dramatically.
