Key Takeaways

• FS722M delivers a 720 × 420 × 650 mm build envelope—30 % larger in height than the FS721M series.
• Eight 1 kW fiber lasers provide up to 1 000 cm³/h volumetric build rate (material‑dependent).
• The CAMS cartridge system isolates part removal from the print chamber, cutting non‑printing time by up to 40 % in reported pilot runs.
• Integrated closed‑loop powder handling keeps the entire material flow under inert gas, reducing contamination risk and limiting routine maintenance to dust‑bin emptying.
• Designed for series production: digital optics, customizable scan strategies, and a refreshed recoater blade ensure repeatable part quality across long‑run builds.

Farsoon Launches the FS722M: A Large‑Format Metal PBF Platform Built for Production

Farsoon Technologies has expanded its metal powder‑bed‑fusion (PBF) portfolio with the FS722M, a machine engineered for high‑volume, repeatable manufacturing. While it inherits core architecture from the earlier FS721M and FS721M‑H models, the FS722M adds a larger build volume, extra laser power, and a novel cartridge‑based workflow aimed at maximizing equipment uptime.

Large‑Format Capacity and Multi‑Laser Productivity

*Rate varies with alloy, layer thickness, and scan strategy.

The rectangular footprint of the FS722M accommodates elongated components—common in automotive and aerospace assemblies—while the 650 mm height enables tall parts or dense vertical nesting, reducing the number of builds required for a given order.

Process Consistency for Series Production

To meet the tight tolerances demanded by serial manufacturing, the FS722M incorporates several hardware upgrades:

• Digital optics with programmable scan vectors allow fine‑tuning of hatch spacing and laser dwell time on a per‑part basis.
• Customizable scanning strategies (e.g., contour‑first, island‑based) improve melt pool stability across the entire build plate.
• An enhanced multi‑layer gas flow system delivers uniform inert atmosphere (≤ 0.1 % O₂) throughout the build volume.
• A reinforced recoater blade reduces powder disturbance, delivering consistent layer thicknesses down to 20 µm.

When paired with application‑specific process qualification, these features translate into part‑to‑part repeatability within ±0.02 mm dimensional tolerance and ≤ 2 % variation in mechanical properties over 100‑part runs.

CAMS: Decoupling Printing from Part Handling

The CAMS (Cartridge‑Based Automated Material System) re‑imagines the traditional build‑plate workflow:

1. Exchangeable build cartridges are loaded onto a conveyor that shuttles them between the print chamber and an external loading dock.
2. Completed cartridges travel to an inerted breakout station where operators or robots remove parts, perform post‑processing, and reseal the cartridge for the next build.
3. While one cartridge is being unpacked, a fresh cartridge is already positioned for the next job, minimizing idle time.

Field trials report a 30‑40 % reduction in total cycle time compared with conventional fixed‑plate systems, directly boosting machine utilization from an average 65 % to over 85 % in high‑mix environments.

Closed‑Loop Powder Management and Automation

The FS722M‑CAMS version integrates a closed‑loop powder handling loop:

• Automated sieving and re‑feeding keep powder particle size distribution within ± 5 % of the original specification.
• Inert storage (argon‑purged) prevents oxidation, extending powder life by an estimated 30 % versus open‑loop systems.
• A built‑in filtration module captures spatter and debris; routine service is limited to emptying a dust bin (≈ 2 kg per 200 h of operation).

This level of automation reduces operator exposure to fine metal powders and aligns with ISO 14644‑1 clean‑room standards for Class 7 environments.

Bottom Line

The FS722M positions Farsoon as a serious contender in the large‑format metal‑additive‑manufacturing market, delivering a 720 × 420 × 650 mm build space, eight 1 kW lasers, and a CAMS cartridge workflow that together target the efficiency and repeatability required for true series production. Its integrated powder‑recycling loop and upgraded process controls further lower per‑part cost and maintenance overhead, making it a compelling option for manufacturers looking to scale metal PBF from prototyping to high‑volume output.
