The specimens are produced using Laser Powder Bed Fusion (LPBF) technology. The main objective of this work is to analyse the fatigue strength of specimens coming from platforms with different level of recycling the input powder, and to investigate the stability of LPBF technology as regards this aspect. The effect of printing powder recycling is questioned. Three different heat treatment setups were applied. Temperature of specimens during the experiment is parallelly monitored to describe the temperature changes during dynamic cyclic loading in order to estimate the fatigue life behaviour in a cost-effective manner. © 2023 The Authors, Published by Elsevier B.V.

Introduction The main focus of this paper is to assess the stability of production quality of the L-PBF process based on the fatigue response of additively manufactured specimens. The research involved the fatigue experiments of specimens produced by the same 3D printer (Concept Laser M2) from multiple printing platforms with a more and more degraded International Conference on Structural Integrity 2023 (ICSI 2023) Fatigue analysis of additively manufactured specimens from AlSi10Mg with different levels of powder recycling Martin Matušů a,b *, Jakub Rosenthal b , Jan Papuga a , Jan Šimota a , Ludmila Džuberová a , Vladimír Mára a and Libor Beránek a a Czech Technical University in Prague, Technicka 4, Prague, 160 00,Czech Republic b Department of Mechanical and Environmental Engineering, OTH Amberg-Weiden, Kaiser-Wilhelm-Ring 23, Amberg 92224, Germany , a b
