Product summary
LM-M280 metal powder bed melting system (commercial designation Metal Forming LM-M280; model TH-M280) with a build envelope of 286 mm × 286 mm × 380 mm. Available in single-laser or optional dual-laser configurations. Capable of processing titanium alloys, aluminum alloys, high-temperature nickel-based alloys, die steels, stainless steels and Co-Cr-Mo alloys. Designed for direct manufacturing of large-size, high-precision, high-performance components for aerospace, tooling and industrial applications.

Key features

• Proprietary process software to optimize scan paths and reduce processing time.
• Optional dual-laser printing — up to ~70% throughput increase compared with single-laser.
• Printed part density >99.5% with mechanical property variation <5%.
• Custom optical system and optimized gas-flow design to ensure high dimensional accuracy and part performance.
• Optimized chamber flow for effective removal of smoke and spatter and uniform full-width builds.
• Real-time equipment status display during printing and automatic generation of electronic build reports; process parameters traceable.
• Automatic detailed process logging: per-layer build records, part temperature, chamber pressure, oxygen level at build position, powder/reservoir positions, recoater position, processing time, etc.
