Journal ArticleDOI
Thermal issues in machine tools
Josef Mayr,Jerzy Jedrzejewski,Eckart Uhlmann,M. Alkan Donmez,Wolfgang Knapp,Frank Härtig,Klaus Wendt,Toshimichi Moriwaki,Paul Shore,Robert Schmitt,Christian Brecher,Timo Würz,Konrad Wegener +12 more
TL;DR: This paper presents a review of the latest research activities and gives an overview of the state of the art in understanding changes in machine tool performance due to changes in thermal conditions (thermal errors of machine tools).
Journal ArticleDOI
Laser based additive manufacturing in industry and academia
Michael Schmidt,Marion Merklein,David L. Bourell,Dimitri Dimitrov,Tino Hausotte,Konrad Wegener,Ludger Overmeyer,Frank Vollertsen,Gideon Levy +8 more
TL;DR: In this paper, an overview over laser-based additive manufacturing with comments on the main steps necessary to build parts to introduce the complexity of the whole process chain is presented. But despite good sales of AM machines, there are still several challenges hindering a broad economic use of AM.
Journal ArticleDOI
Microstructural features of Sc- and Zr-modified Al-Mg alloys processed by selective laser melting
Adriaan B. Spierings,Karl Dawson,Thorsten Heeling,Peter J. Uggowitzer,Robin Schäublin,Frank Palm,Konrad Wegener +6 more
TL;DR: In this paper, the formation mechanisms for these two distinct different structures will help pave the way towards newly designed alloy compositions for the selective laser melting (SLM) process, which is an additive manufacturing technology that offers significant potential for lightweight applications in space, aerospace, and automotive industries as well as in mechanical engineering.
Journal ArticleDOI
Fatigue performance of additive manufactured metallic parts
TL;DR: In this paper, the authors deal with the measurement of the dynamic mechanical properties of two types of stainless steels using selective laser melting (SLM) for dynamic testing in a vertical orientation using SLM.
Journal ArticleDOI
Investigations on the microstructure and crack formation of IN738LC samples processed by selective laser melting using Gaussian and doughnut profiles
TL;DR: In this article, the authors investigated the effect of the laser beam profile on the defect-free processing of the nickel-based superalloy IN738LC using selective laser melting (SLM).
