What your process engineer actually checks
Fine detail, not raw volume
A dynamic focusing system with selectable spot sizes and recoater blades. On a crown margin or a thin lattice the spot size is the spec that decides the part, and on the FS121M you can choose 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 FS121M is a small-frame metal LPBF system built around fine detail rather than volume. Selectable spot sizes and recoater blades, a 4.7×4.7×3.9 in / 120×120×100 mm build cylinder and a single-phase 220 V supply let it sit in a lab or a dental workshop without a plant room.
Why engineers choose the FS121M
Four things your process engineer will check first.
Fine spot, selectable optics
A fully digital scanning system with a dynamic focus and a choice of spot sizes. That is what resolves a crown margin or a thin-walled lattice, where a production frame would simply be the wrong tool.
Runs on a single-phase 220 V supply
14 A on one phase, 1543 lb / 700 kg, a 30.7×39.4 in floor plan. The FS121M needs far less ancillary equipment than a production LPBF cell, which is usually what decides whether it fits your building at all.
Truly open platform
Machine parameters and powder choice are unlocked. For a research group that is the whole point: you can run an unqualified alloy and develop the parameter set yourself.
Ten qualified alloys, including copper
316L, 17-4PH, Ti6Al4V, AlSi10Mg, Maraging 300, HX, pure copper, CuSn10, CoCrMoW and CoCrMo. Copper and cobalt-chrome on a small frame is an unusual combination.
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 30.7×39.4×66.9 in / 780×1000×1700 mm; EUR/China: 220V±10%, 1~/N/PE, 50Hz, 14A. 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 FS121M is built for
Compact Metal LPBF for Dental, Research and Fine Detail. The FS121M runs a single 300 W or 500 W fiber laser with a dynamic focusing system over a 4.7×4.7×3.9 in / 120×120×100 mm build envelope. Full specifications are in the Specifications tab below.
Qualified materials
Farsoon lists 316L, 17-4PH, Ti6Al4V, AlSi10Mg, Maraging Steel Grade 300, HX, pure copper, CuSn10, CoCrMoW and CoCrMo for the FS121M. 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.
