The emergence of green laser technology in metal 3D printing is reshaping the boundaries of additive manufacturing. Han’s Laser HANS M360G represents a new generation of industrial-grade additive manufacturing systems built on green laser innovation. Designed for high-strength, high-precision metal parts, it offers superior performance in material absorption, forming efficiency, and microstructural uniformity — particularly when working with highly reflective metals such as copper, aluminum, and gold.
Why Green Laser? The Science Behind the Advantage
Traditional infrared lasers face significant challenges when processing high-reflectivity metals. These materials reflect most of the infrared light, leading to inefficient energy use, unstable melting behavior, and increased defects such as porosity and spatter.
Differences Between Green Laser and Infrared Laser
Green lasers, however, operate at shorter wavelengths that are far better absorbed by these metals. For instance, copper absorbs roughly 40% of green laser energy, nearly eight times higher than infrared absorption. This dramatically improves energy efficiency, melt-pool control, and surface finish.
Beyond copper and aluminum, green lasers also excel in processing refractory metals like tungsten, tantalum, and molybdenum. These materials are typically difficult to melt uniformly, yet green laser energy provides stable heat input and consistent layer formation, resulting in dense, uniform structures capable of maintaining mechanical reliability under extreme heat and pressure.
Core Technological Modules of HANS M360G
Optimized Airflow Management
A simulation-optimized airflow system ensures uniform wind speed across the build platform. This design efficiently removes fumes and spatter, maintaining a clean and stable processing environment.
Core Technology Modules of the Equipment
Real-Time Process Monitoring
An integrated intelligent monitoring module continuously tracks powder distribution and automatically adjusts the powder supply rate. The system uses smart image recognition to detect under-powdered areas and performs automatic re-coating, maximizing powder utilization and forming consistency.
High-Precision Motion System
The forming axis achieves a repetitive positioning accuracy of ±5 μm, guaranteeing dimensional stability and repeatability for intricate metal structures.
Self-Developed Control Software
Han’s Laser’s proprietary MCS control system provides a powerful, user-friendly interface with comprehensive industrial production capabilities. From process parameter optimization to multi-laser coordination, it ensures stable and efficient printing operations.
Defining Features of the Green Laser 3D Printer
1.Unrivaled Material Adaptability – Equipped with a green laser source, the M360G is compatible with standard SLM metal powders while excelling at high-reflectivity and refractory metals such as copper, aluminum, and tungsten.
2.Superior Precision and Quality – With a smaller spot size (25–50 μm) and higher energy density, the system minimizes heat input, reduces spatter and porosity, and achieves exceptional forming accuracy.
3.Enhanced Durability and Cost Efficiency – Because green lasers reduce reflected energy, optical components experience less thermal stress, significantly extending equipment life and lowering maintenance frequency and costs.
