Farsoon unveils upgraded FS1521M-U with 32 lasers and introduces new Beam Shaping Technology at TCT Asia 2025.
Farsoon unveiled its upgraded FS1521M-U and new Beam Shaping Technology at TCT Asia 2025, advancing capabilities in industrial metal additive manufacturing.
The enhanced FS1521M-U now supports up to 32 × 500W fiber lasers paired with a massive 3,862L build volume. This combination enables faster, high-quality mass production while reducing material waste and improving manufacturing economics.
The FS1521M series has been up and running since 2023 with the first 16 lasers, with 1530mm × 1530mm × 850mm (FS1521M) as the standard build cylinder and 1530mm × 1530mm × 1650mm (FS1521M-U) as the high-cylinder build volume. The series has already been adopted by industrial customers globally since its launch.
The latest FS1521M-U upgrade maintains high precision and part quality while significantly boosting production speeds. The system features 4 overflow and 4 recycling powder hoppers supporting up to 4 powder recycling units, each processing at 90L/h for a combined maximum rate of 360L/h.
Farsoon also introduced its Beam Shaping Technology, designed to improve precision, efficiency, and overall performance in metal powder bed fusion systems. The technology has been integrated into the FS350M-4, featuring quad 1000W lasers and a 433 × 358 × 400mm build volume.
This innovation enables dynamic laser spot configurations that can be tailored to specific applications. By optimizing laser power distribution and scanning strategies, the technology enhances print quality for various materials, achieving part densities exceeding 99.95%.
Beam Shaping Technology increases printing speeds by widening melt pools by 50–100% and boosting build rates by over 2.5 times while minimizing spatter and enhancing thermal stability. It has been demonstrated across multiple Farsoon metal systems and will be extended to larger platforms in the future.
The developments follow Farsoon’s December release of the Flight HT601P-4, a large-format polymer system with four 300-watt fiber lasers, and the November introduction of the FS191M, a next-generation metal powder bed fusion machine for pilot projects and low-volume manufacturing.
