What your process engineer actually checks

Full-coverage dual lasers

Each of the two 500 W lasers reaches the entire build area, so a tall single part gets both of them and a nested plate gets intelligent distribution. No fixed seam your geometry has to dodge.

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 standard.

About this product

The Farsoon FS301M pairs a 12.0×12.0×16.1 in / 305×305×410 mm build cylinder with a dual-laser scanning strategy where each laser covers the entire build area. One large part or a plate of small ones — the machine distributes the work rather than splitting the plate down the middle.

Why engineers choose the FS301M

Four things your process engineer will check first.

Each laser covers the whole plate

Full-coverage dual-laser scanning with calibration algorithms. A tall single part gets both lasers, and a nested plate gets intelligent distribution — not a fixed seam at the centre that your part has to avoid.

Sealed powder handling, one shared container

An integrated powder-loading dock keeps material under inert atmosphere, and one container covers loading, unloading and sieving. Less exposure for the operator and less transfer between stations.

3.61 m² with front and rear access only

The FS301M needs no side clearance, so machines pack tighter than the footprint alone suggests. The integrated filter runs up to 1500 hours between changes.

Pre-heated plate, electric levelling, vision system

Process control details that decide repeatability: a heated base plate, electric levelling and a vision system, with real-time monitoring and an airtight chamber.

How we deliver and support it

What happens between the purchase order and your first qualified part.

Step 01
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 92.9×60.2×84.6 in / 2360×1530×2150 mm; EUR/China: 400V±10%, 3~/N/PE, 50Hz, 15A. The US transformer ships with the machine.

Step 02
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.

Step 03
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 standard.

What the FS301M is built for

Dual-Laser Metal LPBF with Full-Coverage Scanning. The FS301M runs one or two 500 W lasers, each covering the full build area over a 12.0×12.0×16.1 in / 305×305×410 mm build envelope. Full specifications are in the Specifications tab below.

Qualified materials

Farsoon lists 316L, 17-4PH, 420, HX, IN718, AlSi10Mg, TA15 and Ti6Al4V, with HAYNES 230 in process development for the FS301M. 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.

Common questions

Don't see yours? Email [email protected] — NDA standard, typical reply within 4 hours.

Which alloys are qualified for the Farsoon FS301M?
For the FS301M, Farsoon lists 316L, 17-4PH, 420, HX, IN718, AlSi10Mg, TA15 and Ti6Al4V, with HAYNES 230 in process development. Because the platform is open, an alloy outside that list is a parameter development project rather than a blocked path, and our applications engineers scope that work with you. Additive Plus stocks lot-certified metal powder in the USA for the common grades, so reordering does not mean re-qualifying a new supplier mid-programme. Every lot we ship carries a certificate of analysis, which is what keeps a qualified process qualified on reorder.
What does full-coverage dual-laser scanning mean on the FS301M?
On many dual-laser systems each laser owns half the plate, so a part that crosses the middle crosses a seam. On the FS301M both 500 W lasers reach the entire build area, and calibration algorithms distribute the work: a tall single part gets both lasers, a nested plate gets intelligent allocation. Practically, it means you nest for productivity instead of nesting around a fixed boundary, and overlap-zone properties stop being the first thing your metallurgist questions.
Is the FS301M an open system, or are we locked to vendor parameters?
Open. Farsoon unlocks key machine parameters on the FS301M, and BuildStar and MakeStar allow real-time build parameter modification with three-dimensional visualisation and diagnostic functions. On the FS301M teams typically use it to tune how the two full-coverage lasers are allocated across a nested plate, which is where the throughput actually comes from. You can change layer thickness within a build and adapt scanning between infill and detail. The parameter set you develop stays yours, which is the difference between owning a process and renting one.
What part size does the FS301M handle, and what fits in one build?
You have 12.0×12.0×16.1 in / 305×305×410 mm to work with on the FS301M. Treat that as the outer limit rather than the usable volume: orientation and supports always cost you some of it. As a reference point, Farsoon publishes one case on this platform: Aluminium gearbox mount, at 10.8×9.6×7.5 in / 275×245×191 mm. Send us the STL and we will nest it, tell you how many parts fit per plate and estimate the build time before you commit to anything.
What does installation and training in the USA involve for the FS301M?
Installation is ours: we commission the FS301M in the USA, train your operators, and size the cell with your facilities group before you order. The machine envelope is 92.9×60.2×84.6 in / 2360×1530×2150 mm, it weighs 6173 lb / 2800 kg, it runs on EUR/China: 400V±10%, 3~/N/PE, 50Hz, 15A, and the US transformer ships with the machine. Inert gas draw in process is 3 - 5 L/min, and we plan argon or nitrogen supply and extraction with you. First builds are run together with your operators, so what you get at handover is parts and a working parameter set, not a checklist and a manual.
How does the FS301M compare with the other Farsoon metal platforms?
The Farsoon metal range is sized by envelope, not by tier, so start from the part and work outwards. Either side of the FS301M sit the Farsoon FS273M (10.8×10.8×14.0 in with a wider development alloy list) and the Farsoon FS350M (17.1×14.1×15.7 in, 4×500 W, 4×1000 W or 6×500 W). Laser count is the second decision, and it only pays back when nesting keeps every laser busy. Send the part and the annual volume and we will name the frame that pays back, even when that means talking you down a size.
Can we test the FS301M before committing to a purchase?
Yes. Send an STL and we print a paid benchmark part in California, then hand over the part together with the parameter set and a cost-per-part breakdown, so you are judging your own geometry rather than a vendor sample. For the FS301M we usually nest your part alongside filler geometry, because full-coverage dual-laser throughput only shows up on a realistically loaded plate. There is no free sample, but there is no obligation either, and a capability call with an applications engineer costs nothing. We will also confirm the current lead time and the configuration Farsoon is shipping today.
