- ✓ Metre-scale 1530 × 1530 mm platform · up to 32 × 500 W fiber lasers
- ✓ Titanium, nickel superalloy, stainless and aluminium alloys
- ✓ Lead time: configured to order — US install, training and support
What your process engineer actually checks
Multi-laser throughput at metre scale
A 1530 × 1530 mm platform with 16 lasers as standard — up to 32 on the FS1521M-U — prints metre-scale metal parts and high-nest batches. Parallel scan strategies raise build rate with laser count while dual-layer airflow keeps metallurgy consistent across the whole platform.
An applications engineer on the line
We run LPBF in-house at AO Metal — alloy qualification, parameter development and large-part DfAM from engineers who print metal daily. A named engineer replies within 24 hours, NDA standard.
The Farsoon FS1521M is a metre-scale LPBF metal system for serial production. A 1530 × 1530 mm platform runs 16 × 500 W fiber lasers as standard; the FS1521M-U configuration extends the Z-height to 1650 mm — a 3,862 L envelope — and scales to as many as 32 × 500 W lasers. Dual-layer airflow with permanent filtration and powder recycling to 360 L/h keep large metal builds stable and productive. Sold, installed and supported in the US by Additive Plus.
Why production teams choose the FS1521M
Metre-scale metal parts and multi-laser throughput on an open, production-grade LPBF platform.
Metre-scale build platform
A 1530 × 1530 mm platform builds large single parts and high-nest batches at true production scale; the FS1521M-U extends Z to 1650 mm for a 3,862 L envelope.
16 to 32 fiber lasers
Sixteen 500 W fiber lasers as standard, scaling to 32 on the FS1521M-U. Parallel scan strategies drive high build rates across the full 1.5 m platform.
Stable large-area metallurgy
Dual-layer airflow with permanent filtration keeps consistent shielding-gas flow and spatter management across the whole platform for repeatable density and mechanical properties.
Built for continuous production
Dual powder cartridges and recycling units to 360 L/h keep large builds fed and powder recovered — designed for near-continuous metal production.
