Farsoon has introduced its latest Fine Laser Spot metal additive manufacturing solution, which is said to achieve dimensional accuracy down to 0.03 mm.
Supporting materials such as titanium and copper alloys, Farsoon says the Fine Laser Spot capability also yields material density up to 99.99%, enables thin wall structures down to 0.07mm, and delivers surface roughness as low as Ra 2.0 μm.
Farsoon unveiled the capability at TCT Asia earlier this year before also highlighting it at last week’s RAPID + TCT event in Boston. The company sought to develop Fine Laser Spot in a bid to address limitations in resolution and performance in consumer electronics, thermal management and next-generation computing systems. These applications demand tight tolerances, complex internal geometries, and reliable serial production, and with Fine Laser Spot, Farsoon believes it will be better equipped to penetrate the 3C (Computers, Communication, and Consumer Electronics) market.
Per Farsoon, Fine Laser Spot enables the production of end-use or near-net-shape components with minimal finishing requirements. The company is said to have stood up an integrated process chain from parameter development to quality control to ensure consistent results across batches, while also promising reduced process complexity, production cycles and overall manufacturing costs.
One application example offered by Farsoon is the production of copper alloy cold plates for advanced thermal management. By combining TPMS (triply periodic minimal surface) structures with conventional cooling channel designs, Farsoon says it can enable highly efficient heat exchange within a fully integrated component. The ‘ultra-fine processing capability’ allows precise control of internal features, with layer thicknesses down to 10 μm and minimum structure sizes ‘beyond the limits of traditional manufacturing.’ Such a component could be produced in a single piece, rather than assembled from several parts, and would be suitable for electric vehicles, AI data centres, and high-end industrial systems.
