The Farsoon FS421M is a metal laser sintering solution introducing the new patented technology known as CAMS — Continuous Additive Manufacturing Solution. It consists of several integrated modules: build station, loading and filtering station, control station, and automated conveyor system to transport the build cylinder inside the machine. The system like this has been created for intensive manufacturing cycles with minimum downtime between sessions.

The sustainable cooperation of several modules in combination with an impressive build volume of 425 x 425 x 420 mm ensure high throughput for large parts or extended industrial series production. The machine applies a potent 500W dual fiber laser (single option is also available), which possesses increased longevity, compatibility with a wider range of materials, and smaller laser spot size. The build platform heating up to 200 °C and electric leveling functions allow for flexible and streamlined production. With a scanning speed of 15.2 m/s and a minimum layer thickness of 20 microns, the FS421M is a perfect solution for a wide range of applications requiring high production rates and proper quality.

The Farsoon FS421M system comes with an intuitive software solution delivering open build settings, real-time parameters modification, 3D visualization, and diagnostic procedures. Considering the internal rail system that enables the fast exchange of cylinders between builds, the FS421M model ensures smooth and steady workflow. The closed loop powder handling system is equipped with highly efficient air filtration mechanisms. It performs powder supply, building, breakout, and sieving as well as auto-cleaning function under a fully inert atmosphere, which proves completely safe.
