Product name Metal Forming (LM-M800)

Summary The LM-M800 is a powder‑bed laser metal additive manufacturing system with a large build chamber of 807 × 607 × 900 mm. Configurable with 4, 6 or 8 × 500 W laser modules and using multi‑laser precision positioning and splicing control, it supports processing of titanium, aluminum, high‑temperature nickel‑based alloys, mold steels, stainless steels and cobalt‑chromium‑molybdenum alloys. Designed for large‑format applications such as aerospace and tooling, it enables direct production of precision, performance parts.

Key features

• Laser configurations: 4, 6 or 8 × 500 W for scalable productivity.
• Reported maximum forming rates: table spec Max. 210 cm³/h (six lasers); manufacturer cites up to 280 cm³/h depending on process parameters.
• Layer thickness capability: design for ≥60 µm to increase throughput; powder layering range 20–120 µm.
• Scan speed up to 7 m/s with spot diameters 70–120 µm for balance of detail and productivity.
• Multi‑laser precision splicing with overlap deviation ≤0.1 mm to maintain mechanical consistency comparable to single‑laser processing.
• Controlled atmosphere: chamber oxygen ≤100 ppm; protective gases N2 or Ar; preheating/reheating 20–200 °C.
• Real‑time monitoring of process environment and gas supply for stable operation.
• Closed powder handling and recycling with overall sealed design.
• Standard safety features for industrial operation: protection against misoperation, electrical hazards, fire and contamination.
