Recent coverage of Xihe Additive

Why this company matters

AMPulse analysis, not a company disclosure

Xihe Additive (Addireen) is a Shenzhen-based hardware company that has commercialized green laser (532nm) powder bed fusion for metals that are difficult or impossible to process with conventional infrared lasers. It was the first company in China and the second globally to bring a production-grade green laser LPBF system to market, directly addressing the reflectivity barrier that causes IR lasers to scatter off pure copper, gold, and other high-reflectivity materials.

The company's core technology uses proprietary high-power single-mode continuous green fiber lasers (500W–1000W) with an ultra-fine spot size of 15–40μm. This enables stable melting of pure copper at 99.9%+ density and wall thicknesses as low as 0.06mm. Xihe has launched four machine models — from the XH-M100G to the XH-M800G — within 18 months, covering build volumes suitable for jewelry, electronics thermal management, and aerospace heat exchangers.

Xihe targets aerospace engineers, power electronics designers, and high-performance computing thermal management firms. Its 3D-printed minimal surface heat exchangers, including hybrid Gyroid-TPMS structures with Voronoi textures, are marketed for applications requiring high thermal conductivity and power density. The company has partnerships with Nanjing University of Aeronautics and Astronautics and Shanghai Jiao Tong University, and counts undisclosed aerospace and EV firms among its customers.

Competing with TRUMPF and domestic players like Farsoon Technologies and Hollight, Xihe differentiates through its in-house green laser source and custom optical path design. The company has raised $45M from investors including Oriza Holdings, CETC, and SMIC-led funds. A key open question is whether Xihe can scale production capacity and build a service network fast enough to capture demand from aerospace primes and electronics OEMs before larger competitors close the green laser gap.
