In the recent ‘Numerical prediction of distortion. Benchmarking of Additive Works Amphion against real AM component,’ authors Nils Keller and Michal Prugarewicz explore how far metal 3D printing has come.
.
Looking back on a project in 2015, the authors explain that the first pre-serial, completely 3D printed gas turbine part was fabricated and released. Meant for commercial use, manufacturing of this part also meant validation of AM powder technology for an industrial gas turbine.

Researchers continued to work on the design, and it evolved over time—so far as to be installed in machinery for a customer; however, issues with distortion continued to be a problem and project managers realized a solution would be required for ultimate success in production. What was needed was a method for controlling distortion while engineers were involved in the build process. Ex-service component While an application with a nickel-based superalloy Inconel IN738 was considered […]
