PBF laser sintering machine LM-S400

powder bed fusionLPBFfor aluminum

Short description
The LM-S400 is a metal powder bed melting (PBF-LB/M) 3D printer designed for high-precision metal parts production, optimized for shoe-mold details, aerospace, automotive and energy components. It combines a 406×206×230 mm build volume with a three-laser configuration and fine-resolution capability.

Highlights

• Metal powder bed melting (PBF-LB/M) technology
• Three 500 W lasers for increased productivity
• Filtration circulation and controlled-atmosphere chamber (O2 ≤ 100 ppm)
• Tailored powder handling system with high reuse rate; compatible with martensitic stainless steel and aluminum alloys
