Farsoon Technologies, headquartered in Changsha, China, has announced three new Laser Beam Powder Bed Fusion (PBF-LB) Additive Manufacturing machines for the AMEA and US markets: the FS621M Pro Platform, consisting of the FS621M Pro-4 & FS621M Pro-6, and the FS621M-U-4. These machines are targeted for the high-speed production of high-quality, large-scale Additive Manufacturing.

The large-frame FS621M features a build volume of 620 x 620 x 1100 mm. Taking the feedback from the industrial user base and application requirements from aerospace, oil & gas and energy sectors, Farsoon developed the FS621M Pro and FS621M-U-4 machines for larger build volumes and batch production capabilities with materials such as titanium alloys, aluminium alloys, nickel-base superalloys, stainless steels and maraging steels.

The FS621M Pro features a build volume of 620 × 808 × 1200 mm, representing a 30% extension in the Y direction compared to the standard FS621M; it can be equipped with four or six 500 W lasers.

With a build platform size of 620 × 620 mm and a vertical axis of 1.7 m, a 54% increase in the Z height compared to the standard FS621M. The FS621M-U-4 features a build volume of 653 L – reputedly one of the largest in the metal laser sintering market – and four 500 W lasers.

The advanced multi-laser scanning strategy enables high calibration accuracy in the overlapping area in an effort to enable uniform mechanical properties and surface finish of the parts throughout the build platform. In addition, build process control, real-time recording & monitoring capabilities enable good build quality.

The FS621M Pros and FS621M-U-4 can be equipped with a permanent filter module, allowing long-term operation for extremely large builds. The powder handling processes of the two 621M machines share a common powder container design, offering continuous powder feeding to the build and the ability to more easily exchange and monitor powder quality.

Farsoon has announced that it plans on the future release of an FS621M Pro-8 (with an eight-laser configuration) and an FS621M-U-6 (with a six-laser configuration).
