An applications engineer on the line
Questions on build volume, laser config, throughput, or material compatibility? A named applications engineer scopes it directly — not a sales rep. Most replies in under 4 hours, NDA standard.
Highly Productive FS350M-4 System. Featuring an expanded build cylinder of 433×358×400mm and quad 500-watt lasers configuration, the FS350M-4 is capable of producing large metal parts from a wide range of powder materials. The FS350M-4 is ideal for medium to high volume series production of metal parts from a variety of industries such as molds, tooling, automotive and aerospace. The current material capability of powder materials including aluminum, titanium, maraging steels and specialized grades of stainless steels.
Discover FS350M-4 System

- 1-Powder Supply Tank
- The integrated powder supply tank can be easily connected with a powder delivery unit offering a fully sealed material delivery operation under an inert atmosphere without disturbing the build process.
- 2-Glove Box
- The fully sealed glove boxes are located in front of the FS350M-4 system allows convenient and safe breakout operation when the build is completed.
- 3-Integrated Filtration System
- The FS350M-4 is equipped with an integrated, advanced 3-stage reactive material capable recirculating filter module, featured a powerful back-flush function to ensure longer filter life which helps reduce the cost of the filter changes, in addition a permanent filter solution will also be available in the near future further enhancing machine uptime and ease of operations.
- 4-Shared Metal Container
- A shared material container is used during loading, unloading and the sieving procedures offering more convenient powder-handling and transportation between the stations.
- 5-Sieving Unit
- 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.
- 6-Powder Delivery Unit
- The FS350M-4 is featured with 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. The material supply volume can be precisely controlled by the sensor as well.
