FS1521M-U now supports up to 32 500W fiber lasers for aerospace, automotive and energy applications.
Industrial additive manufacturing (AM) supplier Farsoon has announced an upgrade to its FS1521M laser-powder bed fusion (L-PBF) series. When it was launched in 2023, the metal AM machine included 16 fiber lasers and a standard build cylinder of 1530mm x 1530mm x 850mm. A larger version, the FS1521M-U, features a high cylinder build volume of 1530mm x 1530mm x 1650mm for large-format metal parts.
Recently, the company has announced that the FS1521M-U can now support up to 32 500W fiber lasers. According to Farsoon, this is intended to enable faster, higher-quality production and reduce material waste. Designed for serial production, the FS1521M-U has a build volume of 3,862L and multi-laser overlap algorithms that, Farsoon claims, minimize variations and ensure consistent mechanical properties across the entire build.
The upgraded FS1521M Series also includes four overflow/recycling powder hoppers and can support up to four powder recycling units, with a single-unit processing rate of 90L/h, resulting in a combined maximum processing rate of 360L/h. Dual powder cartridges and parallel dual powder conveyors are intended to ensure a steady powder supply for large-scale parts. Farsoon’s dual-layer airflow system with permanent filtration is designed to ensure uniform smoke removal.
According to Farsoon, the updated FS1521M series marks a significant milestone in large-scale industrial metal 3D printing, combining large-format scalability, high-speed multi-laser efficiency, and enhanced cost-performance solutions.
