| Factory Advantage | Tackling the inherent residual stresses of SLM with Ti-6Al-4V is a core competency. The material's low thermal conductivity is a known challenge, but the BLT S800's advanced thermal management provides the stability needed to mitigate distortion during the build. This allows us at MechanoFab to print large, monolithic fuel cell end plates in a single run, completely eliminating the assembly and welding that plagues conventional methods. By leveraging the machine's exceptional gas flow control, we minimize porosity and oxidation, ensuring material integrity compliant with SAE J2579. The result is a near-net-shape component with superior flatness, directly addressing the critical need for uniform stack compression without the cumulative tolerance errors from secondary operations. |
