Farsoon FS191M
What your process engineer actually checks
Locked, traceable lot chemistry
Every lot ships with a COA documenting PSD, sphericity, flow rate, apparent density, and full chemistry — and a lot number you can trace. Aerospace and medical teams reorder 4+ times without re-qualifying.
Qualified parameters, not just powder
Validated parameter sets for EOS M 290, Renishaw 500Q, SLM 280, and our own AO Metal LPBF ship with the order. Load the profile and hit density on the first build — no parameter-development burn.
A materials engineer on the line
Questions on ferrite content, flowability, recyclate ratios, or HIP response? A materials engineer answers directly — not a contact-form bot. Most replies in under 4 hours, NDA standard.
Introducing FS191M System. Farsoon FS191M is a small size, multi-platform, multi-scenario metal system. FS191M provides a wealth of high-end optional functions. Equipped with Farsoon’s low-support technology.
FS191M is offered with robust 500 fiber laser to suit a wide range of application from dental, medical to material development.
The overall dimensions are 1116×845×2005mm, occupying an area of less than 1㎡, which greatly reduces the demand for space; The standard platform (forming cylinder) size is φ191mm×199mm (a small platform is also available), which is the leading forming size in the same class. The whole machine adopts a modular design to improve the convenience of maintenance.

1-Operation Access
2-Filtration System
3-Sieveing Unit
The operation access located in the front of the build chamber offers ease of observation and de-powdering when the build is finished.
The Recirculating Filter System offers efficient filtering of the smoke dust generated in the build chamber during the sintering process. Optional reactive material capable filter system is also available for application needs.
The powder sieving unit features a vibration screen offering efficient sieving of recycled metal powder from the material containers to filter out the large particles. The metal powder collected in the refreshed powder container can be re-used for powder supply.

Support Reduction System
Support-free technology not only reduces material waste but also minimizes post-processing time and costs associated with removing supports. This capability enhances design freedom, enabling engineers and designers to explore more innovative solutions and optimize parts for performance and weight reduction.

Industrial Applications with FS191M
The FS121M is an accessible small frame system allowing the user to select between multiple spot sizes and recoating blades, this combined with a small footprint and reduced need for ancillary equipment allows the FS121M to match customer workspace, material and application requirements. The FS121M is ideal for a wide range of applications from rapid prototyping, low volume production, material development to institution research.

Printing closed impeller with low-support technology
Printing equipment: FS191M
Printing material: nickel-based high-temperature alloy
Industry: aerospace
It is difficult to remove the internal supports of the closed impeller formed by metal laser sintering, and the residual supports seriously affect the quality of the finished product. This closed impeller is formed in one piece using Farsoon’s independently developed low-support technology. Only a small amount of support is designed at the impeller mouth, reducing the amount of support by 99.8%. The internal and external 25-degree inclined structures are formed smoothly without support, greatly reducing the consumption of printing materials and post-processing time, and improving product quality and production efficiency.

Car round radiator
Application: automotive industry
Printing equipment: FS191M
Printing material: aluminum alloy
Sample size: 176 mm×176 mm×168 mm
The radiator produced by traditional manufacturing methods is square, with a single-circuit internal structure, and the connection between the heat pipe and the heat sink is difficult to manufacture. However, with Farsoon’s metal 3D printing solution, this circular radiator can be integrated and has a liquid dual-circuit circulation flow design with additive design. Compared with traditional designs, this circular radiator has a larger heat dissipation area, making heat dissipation more uniform and greatly improving cooling efficiency.

Radiator Housing
Machine: FS191M
Material: Tungsten
Pore size: 0.5-1.5 mm
Build Time: 4 Hours
This radiator housing is developed to prevent deformation of the copper material during high temperature operations, thus extending the life span of the chip radiator. Tungsten is selected for this application for high strength under extreme temperature; but it is also a challenging material to be proceeded by laser sintering technology. Farsoon metal 3D printing can achieve a high part density, advanced porous structure without the need to be further processed.

From process engineers running Farsoon FS191M
Unedited feedback from customers who reorder Farsoon FS191M.
Same lot 4 times in a row. We stopped re-running parameter sweeps after the second order — density was identical to the first build.
Asked about ferrite content on a Friday. A materials engineer answered Monday morning with actual data, not a sales pitch. That's why we keep ordering.
COA matches the bottle. PSD and flow are exactly what was on the sheet — we run it on a Renishaw 500Q and it hits density on the first try.
