Farsoon’s FS811M Offers Large-Format, 12-Laser Metal LPBF Platform

Farsoon’s FS811M is a metal laser powder bed fusion series platform with a large build volume featuring up to 12 fiber lasers. The FS811M series boasts a build volume of 840 × 840 mm² with a Z height of 960 mm for high-volume manufacturing capability. It can be equipped with a robust 6, 8, 10 or 12 × 500-W fiber lasers.

With an XY build platform size of 840 × 840mm and a vertical axis of 960 mm, the FS811M features a build volume of 677 Liters – one of the largest on metal LPBF market. The company says the Z height opens many new manufacturing possibilities in large-scale industrial applications favoring larger Z axis, such as aerospace and aviation, oil and gas, and more. Equipped with up to 12 robust fiber lasers, its high-speed galvo system boosts high production yield up to 300 cm³/hr. The advanced multilaser scanning strategy enables high efficiency distribution as well as calibration accuracy in overlapping areas for uniform mechanical properties of a single over-sized object, or volume-production parts throughout the large build platform.

The FS811M platform features many innovations, such as the all-new multilayer gas flow with advanced wind-wall design to ensure real-time particle removal throughout the whole oversized chamber. The air tightness design of the build chamber enables extreme oxygen content and low inert gas consumption during the build process, ensuring part quality consistency while reducing operational costs. The powerful permanent filtration system enables uninterrupted, reliable process for extreme build times.

The build chamber is equipped with both front and rear doors for ease of operation and maintenance. Once the build is completed, the part cylinder can be transferred to a powder breakout station and part extract station via an integrated conveyor system. The breakout station is fully enclosed and can be accessed through glove boxes on all four sides, enabling multiple operators for powder removal and detail cleaning under a safe inert atmosphere.

The powder handling system shares a common modular powder container design for loading, recycling and sieving under inert gas protection offering continuous powder supply to the build job and the ability to easily monitor powder quality. Like all Farsoon systems, the FS811M is an open platform offering users the flexibility to tailor process parameters for industrial applications and cost-competitive metal additive manufacturing.
