Chinese 3D printing developer Addireen Technologies has introduced the XH-M400G, a four-laser coordinated metal additive manufacturing (AM) system designed for high-precision production.
With a 400 × 400 × 400 mm build volume and an adjustable 20–40 μm laser spot size, the machine supports continuous 24/7 operation and can produce complex features, such as micro-channels, in a single piece. It is capable of batch manufacturing with pure copper, copper alloys, titanium alloys, stainless steel, and tungsten alloys.
“The XH-M400G is perfect for aerospace, electronics, new energy vehicles, data centers, and other advanced industries, setting new standards for complex, large-scale, and highly precise metal parts,” the company stated in a LinkedIn post.
To address the needs of these industries, the XH-M400G integrates a green laser source that improves absorption of reflective materials, reduces spatter, and supports finer detail resolution. Its multi-laser configuration also enables faster processing of copper and copper alloys while maintaining consistent quality.
The system is powered by Addireen’s in-house ADR BP and ADR Print software, which allow simultaneous printing of multiple workpieces with varying layer thicknesses. Users can fine-tune process parameters for different model areas, while an intelligent monitoring system tracks oxygen levels, pressure, and temperature in real time. If a fault occurs, operations are automatically paused to ensure safe and reliable printing.
