Farsoon FS350M-4 Metal AM System Offers Optimal Build Efficiency, Uniform Part Performance

Farsoon’s FS350M-4 is a medium-sized metal 3D production system offering advanced features that enable higher material efficiency and reduced cost. The system is equipped with a  build envelope of 433 × 358 × 400 mm and comes standard with a quad 500-W laser configuration.

The FS350M-4 is well suited for medium- to high-volume series production of metal parts for a variety of industries, including molds, tooling, automotive and aerospace. The current material capability of powder materials includes aluminum, titanium, maraging steels and specialized grades of stainless steels. 

Equipped with advanced multilaser scanning strategy and calibration algorithms, the systems offers optimal build efficiency, and uniformed part performance throughout the build area. Because of the latest process parameters development — including variable layer thickness, adaptive scanning strategies for infill and detail — the FS350M-4 is able to achieve improved productivity along with excellent part quality. For example, with a shoe mold application, the platform is capable of producing over 95% of all shoe sizes of one pair of shoe molds in a single build, with 60% higher build volume rates compared to other metal LPBF systems in its class. 

The metal system includes design features that can reduce the manufacturing cost per part. In large-scale additive manufacturing (AM) production operations, the inert gas consumption is a large portion of the cost. The FS350M-4 limits that expense with its efficient inert gas system as the purge process takes only 11 minutes. During the printing process, the inert gas consumption requires only 3-5 L/min, which the company says is significantly lower than the industry average. 

The platform is equipped with an integrated, advanced 3-stage filter module, featuring a back-flush function to ensure longer filter life which helps reduce the cost of the filter changes. In addition, the company says a permanent filter solution will also be available in the near future which will further enhance machine uptime and ease of operations. The closed-loop Powder Management System, intelligent recoating control and advanced layered gas flow design enable higher material efficiency and reduced cost.

The compact system has a machine footprint of 6 m² with an integrated filtration system. In an AM factory setting, the FS350M-4 enables a high-density layout to achieve maximum throughput per floor area for utilizing a more efficient production layout. 

The FS350M-4 also has a high-efficiency top-feed powder system. Once the powder level in the container runs low, the equipped sensor will release a message for refill. The powder refill unit can be easily docked, enabling quick refill of the material without disturbing the build process.
