What your process engineer actually checks
A research platform, not a cut-down production machine
Two cylinder sizes, a plate that heats past 400 °C, high-resolution melt pool monitoring and unlocked parameters. The specs that matter in R&D are the ones production machines leave out.
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 FS191M is a cylindrical-build metal LPBF system aimed at research and materials development. A ø7.5×7.8 in / ø191×199 mm cylinder, an optional ø80×80 mm small cylinder with a plate heated above 400 °C, high-resolution melt pool monitoring and fully open parameters.
Why engineers choose the FS191M
Four things your process engineer will check first.
Plate heating above 400 °C
With the optional ø80×80 mm small cylinder the build plate heats past 400 °C. That is the configuration for crack-prone and refractory alloys that will not survive a cold plate.
Two cylinder sizes on one machine
ø191×199 mm for parts, ø80×80 mm for powder trials. A small cylinder means a usable experiment on a few hundred grams instead of a full plate of expensive powder.
High-resolution melt pool monitoring
Layer-by-layer melt pool data is what turns a failed build into a result you can publish. The FS191M records it at high resolution rather than logging a pass/fail.
Open platform, support reduction
Machine parameters are unlocked and the support reduction system cuts what you have to remove afterwards — on research parts, post-processing is often the real cost.
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 43.9×33.3×78.9 in / 1116×845×2005 mm. 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 FS191M is built for
Cylindrical-Build Metal LPBF for R&D and High-Temperature Work. The FS191M runs a single 500 W fiber laser over a ø7.5×7.8 in / ø191×199 mm build envelope. Full specifications are in the Specifications tab below.
Powder handling and workflow
Qualified materials
Farsoon lists 316L, Ti6Al4V and AlSi10Mg for the FS191M. 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

A production case, in numbers
| Tungsten lattice radiator blocks | Figure |
|---|---|
| Machine | FS191M |
| Structure | Open-cell lattice and honeycomb radiator blocks |
| Why this frame | Heated plate above 400 °C and open parameters for refractory work |
| Cylinder | ø7.5×7.8 in / ø191×199 mm |
Refractory work of this kind is exactly what the heated small cylinder is for.
