  abstract     = {{Since additive manufacturing (AM) is continuously growing, the influence of processing conditions and setup parameters on microstructural and mechanical properties of additively manufacturedcomponents needs to be clarified. The paper discusses an experimental approach for the identification of influencing parameters in Selective Laser Melting; this consists of an evaluation of the mechanical and physical properties of final parts, depending on the chosen process parameters. The Design of Experiments is used to get valid results from a limited number of experiments. The research work focuses on the application of a Definitive Screening Design to identify the most important influencing parameters: Several parameters of the hatch and the contour exposure are varied, as well as the position and orientation of the samples in the build chamber. A maraging steel and a CoCr alloy are used, and the mechanical and physical properties of the samples are evaluated. The interdependencies between the variation of the factors and the observed properties are analyzed.}},

  abstract     = {{Selective laser melting is a powder bed fusion technology that uses a laser as an energy source in order to directly build fullydensemetal parts. Optimal fabrication requires a comprehensiveunderstanding of the main processing,as it affectsthe part quality.  Wherefore, the objective of this paper is to perform a survey, data checking and collecting ofprovided parameters to compare and contextualize it versus the respective values used in the processby the research studies. The work is focused on cobalt-chromium alloys (CoCr) which are widely used in dental and medical applications. This work focusesonsurfacequality and hardness as built and after the post-processes. As well, the approaches in bond strength after post-processing are considered, comparing the results made by different manufacturing techniques. Finally, this work compares results acquired in surface roughness asbuilt, and tensile strength of parts made by selective laser melting versus the traditional technique cast, before and after heat treatment.}},

  abstract     = {{Selective Laser Melting (SLM) is a powder bed fusion process to produce additively metal parts. From the current point of view, it seems to be one of the most promising additive manufacturing technologies for the production of end use parts. An increasing number of examples prove the successful application of SLM for technical part production. Nevertheless, they also show the enormous effort that is still required to qualify the production process of every single part individually.The present paper gives an overview of the major influencing factors of the SLM process. To get a comprehensive research approach, existing publications on the topic are taken into account as well as own experimental work, evaluating the effects of the process parameters on the relative density of samples made from tool steel. The experimental setup and the results are described and opportunities for the further research work are discussed.}},
