Yet, AM products and processes are often much more complex than thoseobtainedthroughclassicalmanufacturingtechniques,raisingnewques- tions for numerical simulations. Applications for AM products range across many fields in engineering, from design models to lightweight components for the automotive or aerospace industry, or to medical applications like patient specific implants. AM processes involve multi-physics and multi-scale phenomena. Whereas relevantspatialscalesrangeovermanyordersofmagnitude,importanttime scalesstartatmicrosecondsforphysicalprocessesandreachtohoursoreven days. Physics involved include mechanical, thermal, radiation and phase changeproblems. AndmostessentialforsimulationofAMisvalidationand verification. Last but not least a lack of appropriate manufacturing tech- nologies hindered for a long time the realization of designs as obtained, e.g. byshapeand/ortopologyoptimization. InthisregardAMistheidealtech- nology to transfer innovative design proposals to reality. This is the first ECCOMAS thematic conference devoted to this subject. Enjoy. 1

Description:
generation in weld zone of Ti 6Al-4V. The latter requires information about the weld pool behaviour bringing additional challenges. References. [1] Andreas Lundbäck and command optimization is proposed in this paper to maintain the meltpool temperature in DED based on a thermal conductivity
