With the explosive growth of new energy, AI computing power, and commercial spaceflight, copper has become a critical material for thermal management and structural components due to its exceptional thermal and electrical conductivity.
The advantages of metal 3D printing—integrated complex structures and lightweight design—are now driving copper alloys from R&D toward large-scale industrial applications.
The current bottleneck in copper printing has shifted from "whether it can be formed" to "whether it can be produced consistently, stably, and in volume." Laser energy consistency, beam stability, and long-duration operational reliability have become the core benchmarks for next-generation equipment.
To meet this demand, Xihe Additive has launched its third‑generation machine, the XH‑M350G‑2HR. Focused on the pain points of batch production, the system is engineered to make green‑laser copper additive manufacturing truly viable for mass production.
Dual‑laser synergy boosts efficiency
The machine is equipped with a self‑developed dual‑laser system, optional 500W/1000W green laser sources, and a scanning speed of up to 8 m/s. With a maximum build rate of 48.48 cm³/h for pure copper at 80‑µm layer thickness, it lays a solid foundation for scaling up production.
Stable forming across the full build area
Within a 350×350×550 mm build envelope, the optical path has been refined to ensure uniform laser energy distribution across the entire platform. This transforms the effective forming area into genuine batch‑manufacturing capability.
Full closed‑loop control with complete traceability
A closed‑loop system integrating motion, powder spreading, and in‑process monitoring ensures high precision and real‑time anomaly detection. The platform continuously tracks key parameters such as laser power and oxygen concentration, recording all core data to make stability controllable, verifiable, and reproducible.
Proven in practice for long‑run production
Optimized gas flow design effectively removes spatter during processing. The system has already been used for full‑plate batch production and delivery of optical modules for customers. It maintains a consistently low‑oxygen environment with low gas consumption, balancing operational cost and stability.
Targeting applications in AI liquid cooling, optical communications, and aerospace, the XH‑M350G‑2HR is pushing complex copper components from single‑part validation to volume delivery, accelerating the entry of high‑performance thermal management manufacturing into a new phase.
