New Product Release
Green Laser SLM
Infrared SLM
As thermal management requirements for AI computing hardware continue to intensify, copper additive manufacturing is emerging as one of the most critical technological pathways.
HGLaser has officially introduced two intelligent metal additive manufacturing systems-Infrared SLM and Green Laser SLM-forming a dual-technology architecture that spans from high-efficiency mass production to ultra-precision forming. This integrated roadmap enables scalable manufacturing from rapid prototyping to high-volume production for next-generation AI hardware.
01 | AI Computing Constraints and the Search for Thermal Solutions
At the core of AI model competition lies computing power, yet thermal management has become a fundamental physical bottleneck limiting further performance growth.
With GPU power consumption per chip exceeding the kilowatt level and heat flux in high-speed optical modules increasing rapidly, traditional "machining + welding" copper cooling solutions are increasingly inadequate. Straight-channel structures dominate, while welding-induced thermal resistance and leakage risks remain unresolved challenges.
Additive manufacturing, however, enables a paradigm shift-allowing the creation of integrated microchannel structures, topology-optimized heat exchangers, and ultra-thin fins down to 0.1 mm. This opens up entirely new possibilities in thermal design.
As a result, scalable copper additive manufacturing is becoming a decisive factor in the competitiveness of AI hardware supply chains.
Two Technological Routes in Copper Additive Manufacturing
Currently, two mainstream laser powder bed fusion (SLM) approaches dominate copper processing:
Infrared Laser SLM (1064 nm)
Green Laser SLM (532 nm)
These are not competing technologies, but complementary routes optimized for different manufacturing goals.
Infrared systems focus on throughput and cost efficiency, while green laser systems target ultra-high precision and complex structural fidelity.
Infrared SLM vs Green Laser SLM
Copper Absorption Characteristics
Infrared: low absorption rate (<10%), often requiring higher energy input or process compensation
Green: significantly higher absorption (~40%), enabling more efficient energy coupling
System Maturity
Infrared: mature industrial ecosystem with lower cost and stable supply chain
Green: emerging high-end technology with higher system cost
Process Performance
Infrared: supports multi-laser parallel processing, high throughput, and compatibility with aluminum, titanium, and stainless steel
Green: ~40 μm laser spot, higher density, superior surface quality, and reduced post-processing requirements
Typical Applications
Infrared: large-scale server cooling structures and general metal components
Green: pure copper microchannels, high-frequency thermal structures, and ultra-thin fins (down to 0.1 mm class)
Industrial Challenges
Infrared: copper reflectivity affects melt pool stability
Green: higher equipment cost and narrower process window, with limited industrial maturity
In summary, infrared solutions are optimized for scalable production, while green laser technology enables high-end precision manufacturing of copper thermal structures. Together, they cover the full spectrum from industrial volume production to extreme precision engineering.

03 | Full-Chain Manufacturing Capability for Scalable Production
The rapid expansion of AI computing is driving servers, optical modules, and chips toward higher integration and increasingly demanding thermal requirements.
Additive manufacturing-thanks to its ability to produce complex integrated geometries and support rapid design iteration-is evolving from a supplementary process into a core enabling technology.
Focusing on AI thermal management and high-precision optical module components, HGLaser has built a complete additive manufacturing workflow covering prototyping, validation, and mass production. This enables customized manufacturing solutions for industries including 3C electronics, AI communications, low-altitude economy applications, and robotics.
The company integrates laser source R&D, equipment manufacturing, production line engineering, and intelligent control systems into a fully autonomous industrial ecosystem, forming a complete value chain of:
"intelligent equipment – automated production lines – smart manufacturing factories."
Driven by strong demand for copper additive manufacturing in AI-driven industries, HGLaser is accelerating the industrialization of its additive manufacturing business and scaling production capacity.
A new AI high-end thermal component 3D printing intelligent manufacturing base is under construction in the core area of Wuhan Optics Valley, with a planned total area of approximately 80,000 square meters.
Upon completion, the facility is expected to generate an annual output value of 2 billion RMB, positioning it as a globally leading demonstration base for mass production of AI core components via additive manufacturing.
