Features/ Selling points
EXTRA-LARGE BUILD VOLUME

With a build plate size of 620 × 620 mm and a vertical axis measuring 1.1 meters, the FS621M boasts one of the most capacious metal laser sintering build volumes available in the market. Its expansive build envelope unlocks novel opportunities for large-scale metal production, enabling achievements that were previously unattainable in sectors like aerospace, oil and gas, and others.
HIGH PRODUCTIVITY

Equipped with a single 1000 W laser or four 500 W lasers, the FS621M delivers unparalleled productivity. The open platform allows users to customize build parameters for cost-competitive metal additive manufacturing. An advanced dynamic 3-axis scanning system, robust build process control, and real-time recoating monitoring work in tandem to guarantee its top-notch build quality.
OPTIMIZED OPERATION

The filter module is designed with a secondary circulating system and a dual-station filter setup. This enables seamless filter replacement without disrupting the ongoing build process. The powder handling system features a unified powder container design for loading, unloading, and sieving, which offers a fully-sealed powder handling environment, facilitating smooth transportation between different stations and guaranteeing the safe storage of materials.
