Effects of Defects in Laser Additive Manufactured Ti-6Al-4V on Fatigue Properties
TL;DR: In this article, an analysis and simulation of crack propagation behavior considering laser additive manufacturing specific defects, such as porosity and surface roughness, is presented for the mechanical characterization of laser additive manufactured titanium alloy Ti-6Al-4V.
Journal ArticleDOI
Influence of process-induced microstructure and imperfections on mechanical properties of AlSi12 processed by selective laser melting
Shafaqat Siddique,Shafaqat Siddique,Muhammad Imran,Eric Wycisk,Claus Emmelmann,Frank Walther +5 more
TL;DR: In this paper, a series of samples of AlSi12 have been manufactured by SLM process to study the effect of process parameters and post-build heat treatment on the microstructure and corresponding mechanical properties.
Journal ArticleDOI
Influence of Process Parameters on the Quality of Aluminium Alloy EN AW 7075 Using Selective Laser Melting (SLM)
Niko Kaufmann,Muhammad Imran,Tim Marten Wischeropp,Claus Emmelmann,Shafaqat Siddique,Frank Walther +5 more
TL;DR: In this paper, a wide range of process parameters were selected to optimize the process in terms of optimum volume density and the influence of processing parameters on the chemical composition of the selected alloy was determined.
