Learn why Ingersoll Rand needed excellent surface finish standards and repeatable results to an exacting requirement for complex Additive Manufactured printed metal part geometries including internal channels and organic shapes.
PostProcess Technologies has successfully delivered excellent surface finish standards and replicable results to an exacting requirement for complex metal parts with its automated Hybrid DECI Duo solution. In a newly published case study, PostProcess demonstrates the transformative outcome with additive manufactured titanium and nickel alloy shrouded impellers for Ingersoll Rand. After parts arrived off the printer with an R a (roughness average) value that did not meet their specifications, Ingersoll utilized multiple traditional 3D post-printing methods that fell short of their tight tolerance requirements for aerodynamic testing and exacting surface finish needs for aerodynamic performance.
After teaming with PostProcess and utilizing their automated Hybrid DECI Duo solution, Ingersoll has obtained consistent, repeatable Ra results for the 3D printed shrouded impellers as proven through benchmark testing. The software-driven, hands-free DECI Duo delivered parts that consistently passed aerodynamic testing with flying colors, with an average of 70-80% reduction in R a for parts run for 20 minutes or less. While its high quality and consistency requirements led Ingersoll to PostProcess, the ease of operations and cost savings are seen as significant additional advantages.
