What your process engineer actually checks
Laser count scaled to the plate
Two or four 500 W lasers, or eight at 1000 W. Farsoon's calibration keeps part performance uniform across the overlap zones, which is what decides whether an eight-laser plate is usable or just fast.
An applications engineer on the line
Not a ticket queue — engineers who run LPBF in production in-house at AO Metal. Alloy qualification, parameter development, troubleshooting. Sub-4h reply, NDA on request.
The Farsoon FS721M is a long-format production frame: 28.3×16.5×16.5 in / 720×420×420 mm, with two or four 500 W lasers or a eight-laser 1000 W configuration. The shape suits parts that are long — wing structures, rails, shafts — and runs of smaller parts nested down the length of the plate.
Why engineers choose the FS721M
Four things your process engineer will check first.
Up to eight 1000 W lasers
The FS721M-8 configuration puts 8 kW of laser over a 720×420 mm plate. Farsoon's scanning control keeps performance uniform in the multi-laser overlap zones, which is the part that is hard at this laser count.
A 720 mm long envelope
28.3 in in one axis changes what fits in a single build. Long parts stop being an assembly problem, and nested runs of small parts go down the length of the plate instead of stacking.
Conveyor and breakout station built in
An integrated conveyor system moves the build cylinder to a dedicated breakout station for a fully sealed de-powdering process. On a 5000 kg machine, cylinder handling is a real safety question, not a detail.
Continuous feed, monitored recoating
Continuous powder feeding, optimised gas flow, an integrated filter module and real-time recoating monitoring — the set that decides whether a 250-hour build survives.
How we deliver and support it
What happens between the purchase order and your first qualified part.
Scope the cell
We size the configuration against your part mix, then plan power, argon or nitrogen supply and extraction with your facilities team. Machine envelope is 260.2×72.0×98.4 in / 6610×1830×2500 mm; EUR/China: 400V±10%, 3~/N/PE, 50Hz, 32A/40A. The US transformer ships with the machine.
Install and train in the USA
Commissioning and operator training by our US service team. First builds are run together, so your operators hand over parts rather than a checklist.
Parameters, spares, engineer
Validated parameter sets for your alloy, US-held spares, and an applications engineer who has run LPBF in production in-house at AO Metal. Sub-4h reply, NDA on request.
What the FS721M is built for
Large-Format Metal LPBF with up to Eight 1000 W Lasers. The FS721M runs two or four 500 W lasers, or eight 1000 W lasers over a 28.3×16.5×16.5 in / 720×420×420 mm build envelope. Full specifications are in the Specifications tab below.
Powder handling and workflow
Qualified materials
Farsoon lists 316L, TA15 and Ti6Al4V as qualified grades, with AlSi10Mg, IN718, HX and Maraging Steel Grade 300 in process development for the FS721M. Because the platform is open, a grade outside that list is a parameter development project rather than a dead end, and one we can run with you. The alloys we stock are lot-certified and held in the USA.
