3D Printed Pressure Vessel Surpasses Test Expectations

The Finnish metal industry has achieved a new milestone with its largest metal 3D print, a pressure vessel, enduring a pressure of 111 bars during testing. This is a substantial improvement over the preliminary estimations of a 90-bar threshold.

The collaboration between ANDRITZ Savonlinna Works Oy and the FAME Ecosystem yielded a vessel designed for a nominal 10-bar pressure, factoring in safety margins. The non-destructive testing (NDT) and subsequent destructive tests were administered by LUT University, revealing the robustness of the Wire Arc Additive Manufacturing (WAAM) technique on a large scale, which was previously untested.
