In addition to the extra-large build volume, the FS1521M series also offers circular and square build cartridge configurations to meet a broad range of application needs. The FS1521M-U square cartridge features a significant build volume of 3,862 Liters – one of the largest in the metal laser-powder bed fusion market.
Thanks to the new calibration algorithms deployed on the 16-laser scanning strategy, each laser’s operation and overlap can be precisely controlled, ensuring uniform mechanical properties of the parts throughout the build area. The advanced multi-laser scanning strategies offer optional modes towards efficiency, quality, or balanced performance for different manufacturing needs. With a high build rate of up to 400cm³/h (eg 3.27kg/hr in Inconel, for example), the FS1521M series offers maximized printing speed for large-format parts, or reduced manufacturing cost for volume series production.
Additionally, to further enhance part quality and operational flexibility, the FS1521M series features innovative gas flow design ensuring stable, real-time particle removal throughout the large platform. Parallel permanent filtration systems allow uninterrupted operations for extreme build times.
The contactless, closed-loop powder handling system includes powder supply, recycling and sieving; is conducted under a fully inert gas-protected system for operational safety. Thanks to the modular and redundant powder container design the FS1521M offers continuous feeding and collection of overflow powder for an easy, streamlined powder management process.
