Technology & Products
Key Products
Xihe Additive specializes in 3D-printed minimal surface heat exchangers, including TPMS and hybrid Gyroid-TPMS structures with Voronoi textures, achieving significant improvements in heat transfer efficiency and power density for applications like aerospace and industrial processes.
Technological Advantage
Utilizes proprietary high-power single-mode continuous green fiber lasers (500W-1000W) with a ultra-fine spot size (15-40μm), allowing for 0.06mm wall thickness and superior surface finish.
Differentiation
Value Proposition
Enables stable, high-density (99.9%+) 3D printing of pure copper with electrical conductivity exceeding 100% IACS by utilizing green laser technology that offers 8-10x higher energy absorption than traditional infrared lasers.
How They Differentiate
Pioneered China's first commercial green laser (532nm) LPBF system, utilizing proprietary high-power continuous green fiber lasers for superior cost control and custom-tuned optical paths. Additionally, they differentiate through advanced research and partnerships, such as their collaboration with NUAA on high-efficiency 3D-printed heat exchangers with innovative structures like hybrid Gyroid-TPMS with Voronoi textures.
