Farsoon’s upgraded laser increases accuracy in batch production
April 1, 2025
Farsoon Technologies, based in Changsha, China, has announced an upgraded laser for precision batch production on its FS200M dual-laser Laser Beam Powder Bed Fusion (PBF-LB) Additive Manufacturing machines. The upgrade features a 40 μm laser spot that can produce parts with Ra 3.0 μm surface roughness and 0.05 mm accuracy at 0.1 mm wall thickness.
Laser spot size plays a crucial role in build resolution, material density, and part quality, explains Farsoon. Standard laser sizes in Additive Manufacturing are said to typically achieve 0.1 mm accuracy and Ra values between 7.0–20 μm. However, industries like consumer electronics, medicine and precision molding demand tighter tolerances, smoother surfaces, and minimal post-processing to control costs and enhance scalability.
Using the new laser will enable manufacturers to additively manufacture fine-resolution, dense components that can include hollow parts, hinges, intentionally porous areas and conformal cooling patterns. In one example, Farsoon found that using its 40 μm laser spot and a 30 μm layer thickness resulted in the development of aluminium alloy parts with 99.99% density.
Farsoon also noted that its multi-laser coordination technology enables ±0.05 mm laser overlap accuracy, maintaining consistent mechanical properties across the build and optimising layer thickness control. These characteristics can lead to reduced post-processing, thus cutting production time and costs.
