Discover FS1521M System

The build Station is where the sintering process takes place. Once the build packet files are loaded into Farsoon’s BuildStarTM operating software, the build process begins. The build chamber is featured with front and rear access door for ease of operation.
The FS1521M’s integrated permanent filter module features two parallel circulating system and a dual-station filter design that allows for uninterrupted operations for extreme build times.
The powder conveying unit operates in a fully inerted atmosphere, ensuring a fully enclosed and safe powder transfer process. Designed for high efficiency, it enables long-distance, high-volume powder transport, maintaining material integrity and process stability.
The build cartridge is moved to breakout station via the internal conveyor system. The Breakout Station is fully enclosed and is accessed through glove boxes on 3 sides of the station allows the capability of 6 operators while retaining a clean working environment. The convenient air-gun and vacuum hose access allow for gentle powder removal and detailed cleaning.
The powder returning unit is equipped with a high-efficiency negative pressure powder suction system designed for the large-volume collection of metal powder from the breakout station in a fully inerted atmosphere, ensuring a smooth transfer to the sieving process for reuse.
Once the breakout process is complete, the build cartridge is transported to the part extraction area via the internal conveyor system. For further post-processing, the cartridge can be safely lifted and handled using a crane system, ensuring efficient and secure operation.
The powder sieving unit features a vibration screen offering efficient sieving of recycled metal powder from the overflow & recycled powder hoppers to filter the large particles. The metal powder collected in the refreshed powder hopper can be re-used for powder supply.
