Farsoon introduces twelve-laser FS811M metal Additive Manufacturing machine
May 8, 2024
Farsoon Technologies, based in Changsha, China, has added the FS811M to its range of metal Laser Beam Powder Bed Fusion (PBF-LB) Additive Manufacturing machines. With the option for six, eight, ten or twelve 500 W fibre lasers, the FS811M series has a build volume of 840 x 840 x 960 mm and is geared towards high-volume manufacturing.
“Being the latest addition to Farsoon’s metal 3D printer portfolio, the FS811M grew out of a co-innovation project with our key industry customers operating multiple FS621M systems,” shared Wenyu Guo, Vice-director of Farsoon metal product line management. “We’ve spent the past two years developing and optimising the FS811M platform for specific application projects.”
“Starting one year ago, we start to see the rapidly expanding large-format metal 3D printing application in aerospace, oil & gas, energy and automotive sectors, the industry customers are drawing greater requirements for manufacturing efficiency, reliability, and larger build size than FS621M,” Guo continued. “This is when we decide to fully commercialise the FS811M platform to scale up metal series production.”
With an XY build platform size of 840 x 840 mm and a vertical axis of 960 mm, the FS811M features a total build volume of 677 litres and is reported to be one of the largest on the metal PBF-LB machine market. The Z height is intended to open many new manufacturing possibilities in large-scale industrial applications in aerospace, oil & gas and more.
Equipped with up to twelve fibre lasers, the high-speed galvo system boosts a production yield of up to 300 cm3/h. The advanced multi-laser scanning strategy enables high-efficiency distribution and calibration accuracy in the overlapping area for uniformed mechanical properties of a single over-sized object or volume-production parts throughout the large build platform.
The FS811M platform features a multi-layer gas flow. The design enables high oxygen content and low inert gas consumption during the build process, enabling part quality consistency and reducing operational costs. The permanent filtration system allows an uninterrupted, reliable process for extreme build times.
The FS811M build chamber is equipped with both front and rear doors in an effort to ease operation and maintenance. Once the build is completed, the part cylinder can be transferred to the powder breakout and part extract stations via an integrated conveyor system. The breakout station is fully enclosed and can be accessed through glove boxes on all four sides, allowing multiple operators for powder removal and detail cleaning under a safe, inert atmosphere.
The FS811M powder handling system shares a common modular powder container design for loading, recycling, and sieving under inert gas protection, offering a continuous powder supply to the build job and the ability to monitor powder quality.
