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.

About this product
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.

Common questions
Don't see yours? Email [email protected] — NDA standard, typical reply within 4 hours.
How large a part can the FS1521M build?
The FS1521M has a 1530 × 1530 mm platform; the standard build height is 850 mm and the FS1521M-U configuration extends it to 1650 mm — a 3,862 L envelope. That lets you print metre-scale single metal parts or dense nested batches that smaller LPBF systems must split across multiple builds.
How many lasers does the FS1521M have?
The standard FS1521M runs 16 × 500 W fiber lasers; the FS1521M-U configuration scales to as many as 32 × 500 W lasers. The lasers scan in parallel with overlapping fields across the 1.5 m platform, so build rate rises with laser count while metallurgy stays consistent.
What alloys does the FS1521M run?
The FS1521M runs Farsoon's open metal library: titanium (Ti-6Al-4V, TA15), nickel superalloys (IN718, HX), stainless 316L, aluminium AlSi10Mg and maraging tool steel. Because parameters are open, Additive Plus can help qualify additional alloys and supply validated parameter sets for your material.
How does it keep metallurgy consistent over such a large area?
The FS1521M uses a dual-layer airflow system with permanent filtration to hold consistent shielding-gas flow and remove spatter uniformly across the whole 1.5 m platform. Combined with multi-laser calibration, this supports repeatable density and mechanical properties from edge to centre of the build.
What powder handling does the FS1521M include?
The FS1521M uses dual powder cartridges with parallel conveying and up to four recycling units running at 90 L/h each — up to 360 L/h combined. That keeps large builds fed and recovers unused powder, supporting near-continuous metal production on the large platform.
What layer thickness and atmosphere does it use?
The FS1521M runs 0.02–0.10 mm (0.0008–0.0039 in) layers under an argon or nitrogen atmosphere, selected by alloy. Thinner layers favour resolution and surface finish; thicker layers raise build rate on robust alloys. Additive Plus supplies the parameter set that matches your alloy and part goals.
What does delivery, install and support look like?
This is capital equipment: Additive Plus handles facility, gas and power planning, US installation and commissioning, operator training on BuildStar / MakeStar®, qualified alloy parameters and local warranty and service. Lead time is configured to order and leasing or financing is available — request a quote and a named engineer will confirm timing and configuration.
