Installation and commissioning in the USA: facility and gas planning, start-up and operator training by our US service team.
What your process engineer actually checks
The alloy list is the differentiator
Copper, tungsten, tantalum and CuCrZr on a standard production frame. If your roadmap includes a refractory or high-conductivity alloy, this is the frame that does not close the door on it.
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 FS273M is a cost-performance LPBF frame with an unusually deep alloy list. A 10.8×10.8×14.0 in / 275×275×355 mm envelope, one or two 500 W lasers at up to 49.9 ft/s, and development grades that run from tool steel to copper, tungsten and tantalum.
Why engineers choose the FS273M
Four things your process engineer will check first.
An alloy list that goes past the usual four
Beyond 316L, Maraging 300, AlSi10Mg and Ti6Al4V, Farsoon lists pure copper, tungsten, tantalum, CuCrZr, H13, IN718 and AlMgScZr in development on this frame. Few machines in this size class reach that far.
49.9 ft/s scanning, single or dual laser
Up to 15.2 m/s with a choice of F-theta lenses or a dynamic focusing system. Start single-laser and the FS273M-2 dual configuration is the same frame, so the decision is about payback, not about replacing the machine.
Built for long builds
An integrated long-life filtration system, a pre-heated base plate, removable overflow containers and a powder supply sized for a full build. The details that decide whether a 355 mm tall build finishes unattended.
Truly open parameters
Advanced digital optics and unlocked process parameters. That is what makes the development-grade alloy list usable rather than decorative.
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 91.1×65.0×82.9 in / 2315×1650×2105 mm; EUR/China: 400V±10%, 3~/N/PE, 50Hz, 20A single laser / 30A dual. 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 FS273M is built for
Metal LPBF with the Widest Alloy List in Its Frame Size. The FS273M runs one or two 500 W lasers (FS273M / FS273M-2) over a 10.8×10.8×14.0 in / 275×275×355 mm build envelope. Full specifications are in the Specifications tab below.
Powder handling and workflow
Qualified materials
Farsoon lists 316L, Maraging Steel Grade 300, AlSi10Mg and Ti6Al4V as qualified grades, with HX, AlMgScZr, TA15, AlSi7Mg, 420, IN718, H13, pure copper, tungsten, tantalum and CuCrZr in process development for the FS273M. 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.
Typical applications

| Machine | FS273M |

Case as published by Farsoon for the FS273M.
Porous tantalum and titanium, on the same frame
Two published FS273M parts show how far the alloy list reaches: a porous tantalum knee implant with a bone-like lattice, and a topology-optimised titanium suspension upright. Tantalum is a refractory metal most LPBF platforms will not touch; here it is a development grade on a standard production frame.
