What your process engineer actually checks
Multi-laser throughput you can verify
Four 500 W, four 1000 W with Beam Shaping, or six 500 W lasers over the same build cylinder. Scanning at up to 32.8 ft/s / 10 m/s, recoating at 400 mm/s, roughly 8 seconds per layer. We hand you the parameter set behind any figure we quote, not just the figure.
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 FS350M is a multi-laser LPBF platform for medium- to high-volume metal series production, available in three laser configurations — 4×500 W (FS350M-4), 4×1000 W with Beam Shaping and 6×500 W. All three share the same 17.1×14.1×15.7 in / 433×358×400 mm build cylinder and the same 65 sq ft / 6 m² class footprint, in 316L, AlSi10Mg, Ti6Al4V, 17-4PH, ST1 and Maraging Steel Grade 300.
Why engineers choose the FS350M
Four things your process engineer will check first.
Laser power matched to your part mix
Four 500 W, four 1000 W with Beam Shaping, or six 500 W lasers — same build cylinder either way. Scanning runs at up to 32.8 ft/s / 10 m/s, with recoating at 400 mm/s and roughly 8 seconds per layer.
Truly open platform
Key machine parameters are open. BuildStar and MakeStar allow real-time build parameter modification, so you can qualify an in-house alloy or tune a recipe instead of waiting for a vendor release.
Closed-loop powder management
Sealed supply tank, front glove boxes for breakout, and one shared container for loading, unloading and sieving. Powder stays under argon or nitrogen from delivery through recycling.
Three-stage filtration with back-flush
An integrated three-stage filter module rated for reactive materials. Back-flush extends filter life and cuts the cost of filter changes. Full chamber purge takes 11 minutes; inert gas draw in process is 3–5 L/min.
Three configurations on one platform
Farsoon builds the FS350M in three laser configurations. The build cylinder, the footprint and the powder handling do not change between them — what changes is how much laser you put over the same plate. We supply all three.
| Configuration | Lasers | What it is for |
|---|---|---|
| FS350M-4 | 4 × 500 W | The established baseline, with over 100 systems installed in the consumer products sector alone. The default choice for mixed series production. |
| FS350M 4×1000 W | 4 × 1000 W + Beam Shaping | Double the laser power plus Beam Shaping, which widens the melt pool. Farsoon states up to twice the build efficiency of the 4×500 W configuration, and better support for specialty alloys. |
| FS350M 6×500 W | 6 × 500 W | Developed with industry partners for industrial-scale throughput on serial runs of small to medium parts, where nesting keeps every laser busy. |
Build cylinder 17.1×14.1×15.7 in / 433×358×400 mm and the 6 m² class footprint are the same on all three. Productivity claims are Farsoon's; which configuration pays back on your part mix is the conversation to have before the order.
How we deliver and support it
What happens between the purchase order and your first qualified part.
Pick the configuration, scope the cell
We size the laser count against your part mix and annual volume, then plan power, argon or nitrogen supply and extraction with your facilities team. Footprint is 65 sq ft / 6 m² class with filtration integrated; 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 FS350M is built for
The FS350M-4 ran in serial production at customer sites for close to two years before Farsoon released it to the global market. The platform sits in the range where a part has stopped being a prototype: molds and tooling, automotive and aerospace hardware, and consumer parts produced in repeating batches. Process parameter development — variable layer thickness, adaptive scanning for infill versus detail — is what raises throughput without giving up part quality. Full specifications are in the Specifications tab below.
Build chamber and powder handling
- 1 — Powder supply tank. Connects to the powder delivery unit for fully sealed material delivery under an inert atmosphere, without disturbing the build in progress.
- 2 — Glove box. Sealed glove boxes at the front of the machine allow safe breakout once the build is complete.
- 3 — Integrated filtration system. Three-stage recirculating filter module rated for reactive materials, with a back-flush function that extends filter life.
- 4 — Shared metal container. One container for loading, unloading and sieving, which simplifies powder handling and transport between stations.
- 5 — Sieving unit. A vibration screen filters oversize particles out of recycled powder; refreshed powder goes straight back into supply.
- 6 — Powder delivery unit. A top-feed system tracks powder level in the container and signals a refill; the refill unit docks and tops up material without disturbing the build.
Qualified materials
Farsoon lists 316L, AlSi10Mg, Ti6Al4V, 17-4PH, ST1 and Maraging Steel Grade 300 for the FS350M, with further grades in process development. 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. We stock 316L, AlSi10Mg and Ti-6Al-4V in the USA, lot-certified.
