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.

About this product

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.

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 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.

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 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.

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.

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.

Common questions

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

Which alloys are qualified for the Farsoon FS273M?
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, 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. Ask us for the certificate of analysis format before you commit — it is what your AS9100 auditor will want to see.
Can the FS273M really print copper, tungsten and tantalum?
Farsoon lists pure copper, tungsten, tantalum and CuCrZr for the FS273M as process development grades, not as qualified production parameters — that distinction matters. It means the platform and the optics support them and that parameter development is a project you can actually start, rather than a closed door. Qualified grades on this frame are 316L, Maraging Steel Grade 300, AlSi10Mg and Ti6Al4V. If a refractory or high-conductivity alloy is on your roadmap, talk to our applications engineer about scoping the development work first.
Is the FS273M an open system, or are we locked to vendor parameters?
Open. Farsoon unlocks key machine parameters on the FS273M, and BuildStar and MakeStar allow real-time build parameter modification with three-dimensional visualisation and diagnostic functions. On the FS273M this is what makes the development alloy list usable at all — copper, tungsten, tantalum and CuCrZr need parameters you develop, not parameters you are handed. 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 FS273M handle, and what fits in one build?
The FS273M build envelope is 10.8×10.8×14.0 in / 275×275×355 mm. Functional build volume is always a little smaller than the stated cylinder, because it depends on part geometry, orientation and the support strategy you choose. As a reference point, Farsoon publishes one case on this platform: Mold inserts with conformal cooling. 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 FS273M?
Our US service team commissions the FS273M and trains your operators, and we plan the cell with your facilities group before the order goes in. The machine envelope is 91.1×65.0×82.9 in / 2315×1650×2105 mm, it weighs approximately 4850 lb / 2200 kg, it runs on EUR/China: 400V±10%, 3~/N/PE, 50Hz, 20A single laser / 30A dual, 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 FS273M compare with the other Farsoon metal platforms?
Farsoon's metal line is a ladder of build envelopes rather than a good-better-best range, so the frame is chosen by part size first. Either side of the FS273M sit the Farsoon FS200M-2 (16.7×9.1×11.8 in dual-laser frame for long parts) and the Farsoon FS301M (12.0×12.0×16.1 in with full dual-laser coverage). Laser count is the second decision, and it only pays back when nesting keeps every laser busy. Tell us your part envelope, alloy and annual volume and we will say which frame actually fits — including when a smaller one is the right answer.
Can we test the FS273M 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 FS273M, if your interest is one of the development alloys, the benchmark is really a parameter study and we scope it as one before quoting. 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.
