As industries like aerospace, automotive, and energy demand larger, high-performance components, traditional manufacturing struggles with long lead times and high costs. Addressing these challenges, Farsoon introduces the FS1521M Series with 16 lasers in 2023 features a standard build cylinder of 1530mm × 1530mm × 850mm (FS1521M), or high cylinder build volume of 1530mm × 1530mm × 1650mm (FS1521M-U) engineered for industrial-scale serial production of large-format metal parts. Since its launch, the FS1521M series has been widely adopted by industrial customers worldwide for its advanced design and exceptional performance.
With key enhancements driving industrial-scale production, the FS1521M-U configuration now can support up to 32 × 500W fiber lasers, offering unprecedented efficiency, scalability, and cost-effectiveness. This breakthrough enables faster, high-quality mass production, reducing material waste and improving true economic manufacturing.
1 | 32 Lasers: High-Efficiency Printing with Precision
With up to 32 powerful 500W fiber lasers and build volume of 3,862 Liters, the FS1521M-U significantly accelerates production while maintaining exceptional part quality. Advanced multi-laser overlaps algorithms ensure consistent mechanical properties across the entire build, keeping low variations — a major breakthrough for serial production.
2 | Next-Gen Powder & Airflow Management for Large Builds
The upgraded FS1521M Series features 4 overflow / 4 recycling powder hoppers and can support up to 4 powder recycling units, with a single-unit processing rate of 90L/h and a combined maximum processing rate of 360L/h. When it comes to the material supply, its dual powder cartridges design and parallel dual powder conveying units ensure a steady, robust powder supply for large-scale parts, delivering a more efficient and seamless production operation.
The dual-layer airflow system with permanent filtration ensures uniform smoke removal, crucial for large-span prints. Meanwhile, automated powder handling improves safety and efficiency.
3 | Large-Format + Flexibility: Scalable for Production Needs
The FS1521M series, including the standard FS1521M and high-cylinder FS1521M-U, features a unique, versatile platform offering multiple circular or square build volume configurations. This flexibility optimizes powder usage, reduces costs, and enhances adaptability for industrial application needs.
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.
