【 摘 要 】

In order to investigate the capability of additive manufacturing technologies to build pressure housings, hemispheres made of titanium and ceramic with a nominal outer diameter of 70 mm were built on 3D printer systems, evaluated, and tested in a pressure tank. Titanium hemispheres expected to withstand an external pressure of 10 MPa started buckling at 6 MPa. A stiffened titanium hemisphere which was expected to withstand 24 MPa collapsed at 30 MPa. A ceramic hemisphere could not be tested to collapse since the measurement technique was not rated to withstand an external pressure above 30 MPa. (C) 2016 The Authors. Published by Elsevier Ltd.
