A 3D-printed cold-isostatic-pressing capsule — porous internal core plus external shell — pressed Ti-6Al-4V powder from inside and outside at once, forming a crack-free three-way pipe. Sintered at 1230 °C it hit 929 MPa tensile, 862 MPa yield, 15.5% elongation, 382 HV — matching the ASTM B381 forging standard. Abstract from a web-indexed copy of the publisher record. Based on the paper: Ti Alloy Three-Way Pipe Fabricated by the Combination of 3D Printing and Cold Isostatic Pressing; Y. Shao, F. Yang, P. Liu, Z. Feng, X. Lu, Z. Guo, H. Xu, A.A. Volinsky; Journal of Materials Engineering and Performance, 2019, Vol. 28, pp. 6219–6227. Hosts Elena and Marcus. AI-generated voices.
