During TCT Asia 2023, technology innovator Farsoon showcased a major breakthrough in the production of complex metal structures. The company has successfully developed the revolutionary SRS Technology – Support Reduction System, which enables significantly fewer supports compared to the standard metal PBF process; it enables fabrication of inverted conical structures and horizontal circular holes with no support. Farsoon now proudly presents the SRS technology to the global market.
The SRS innovation addresses one of the most challenging aspects of additive manufacturing—internal stress and deformation during the cooling phase of metal powder bed fusion, which can lead to part failure, especially in overhanging structures. Applicable to all Farsoon metal PBF platforms, the new SRS technology successfully forms inverted conical structures with a 20°-25° angle and support-free horizontal circular holes up to 50mm in diameter (See figure 1).

The advancement significantly reduces the need for support structures, which are traditionally necessary for low-hanging angles (typically below 45 degrees) to mitigate the risk of part failure. This not only saves on material costs and reduces printing and post-processing time but also minimizes potential damage to the part, enhancing both efficiency and quality in sectors like aerospace and automotive.
The use of Farsoon’s proprietary slicing software and adaptive intelligent scanning strategies allows for precise control of energy input and local part temperature. This ensures high part density and significantly improves the capability of forming low-angle structures over traditional scanning technologies.
The benefits of the SRS support-reduction technology extend beyond cost and time savings for material, fabrication and post-processing. It offers increased design freedom and reducing the constraints imposed by traditional manufacturing methods. For example, a closed impeller made of IN718 material, approximately 130mm in diameter and 50mm in height, can now be printed 33% faster, with cost reductions exceeding 25%.
Farsoon has applied this minimal support technology to a variety of real-world materials and applications, including titanium alloys, high-temperature alloys, aluminum alloys, and stainless steel. Applications range from combustion chambers to closed impellers, valve bodies, and nozzles, with the largest parts exceeding 450mm.
