Farsoon’s LPBF Systems for Large-Scale Metal Additive Manufacturing

Farsoon’s latest metal additive laser powder bed fusion systems (LPBF) include the FS621M Pro-4, FS621M Pro-6 and the FS621M-U-4, which are available to the AMEA and U.S. market for pilot customer application. These multilaser, large-format metal platforms are targeted for high-speed production of high-quality large-scale additive manufacturing (AM). 

These new systems are said to offer huge potential in aerospace applications by lowering operational cost and enabling true industrial-scale series manufacturing. 

The large-frame FS621M has a build volume of 620 × 620 mm² with a height  of 1,100 mm. This metal system is said to offer unparalleled production for large-scale applications that favor higher Z axis.

Farsoon further developed the FS621M Pro and FS621M-U-4 platforms for even higher build volume fabrication and batch production capabilities with materials such as titanium alloys, aluminum alloys, nickel-based superalloys, stainless steels and maraging steels. 

The FS621M Pro Platform features a build volume of 620 × 808 × 1,200 mm with a 30% extension in Y direction compared to the standard FS621M. It can be equipped with 4 × 500-watt or 6 x 500-watt lasers to boost productivity for series manufacturing. 

Farsoon’s FS621M-U-4 features a build platform size of 620 × 620 mm and a vertical axis of 1.7 meter (a 54% increase in Z height compared to the standard FS621M). It has a build volume of 653 Liters – one of the largest in the metal laser sintering market, the company says. The Z height and fiber lasers are said to enable many new possibilities in large-scale industrial applications.

The advanced multilaser scanning strategy is designed to enable high calibration accuracy in overlapping areas, ensuring uniform mechanical properties and surface finish of the parts throughout the build platform. In addition, the build process control, real-time recording and monitoring capabilities ensure optimal build quality.

To further enhance productivity and quality, the FS621M Pro Platform and FS621M-U-4 can be equipped with a permanent filter module enabling long-term operation for extremely large builds. The powder handling processes of the two 621M systems share a common powder container design, offering continuous feeding of powder to the build and the ability to easily exchange and monitor powder quality.
