Journal ArticleDOI
Combining alloy and process modification for micro-crack mitigation in an additively manufactured Ni-base superalloy
Seth Griffiths,H. Ghasemi Tabasi,Toni Ivas,Xavier Maeder,A. De Luca,Kai Zweiacker,Rafal Wrobel,Jamasp Jhabvala,Roland E. Logé,Christian Leinenbach +9 more
TL;DR: In this article, the authors demonstrate the importance of both processing conditions and alloy chemistry on micro-cracking in L-PBF fabricated γ` hardening Ni-base superalloys.
Journal ArticleDOI

TL;DR: In this article, an inter-laboratory test is conducted to check if additive manufacturing technologies are suitable for reproducing porous samples designed for sound absorption, in which the production of samples and their acoustic measurements are carried out independently by different laboratories, sharing only the same geometry codes describing agreed periodic cellular designs.

Proceedings ArticleDOI
Cyclic testing of 1:40 scale cantilever rc elements with digitally manufactured reinforcement
Lorenzo Del Giudice,Rafal Wrobel,Antonios A. Katsamakas,Christian Leinenbach,Michalis F. Vassiliou +4 more
TL;DR: In this paper, the results from cyclic tests on 1:40 scale RC cantilever columns were presented, and the reinforcement cages were manufactured using a Selective Laser Melting 3D printer that was able to print rebars with submillimeter diameter and yield strength 378MPa.
