Selective laser melting is the additive manufacturing process for metallic materials. This technology is the mechanism of the layer by layer building object. The main application areas of this technology are part of a complex shape and specific features. The robustness of the process will increase by online control of the process.
The framework of this research consists of two systems: a real time monitoring of melt pool and an impact of the energy density on the different parameters of the sample building.
Energy density is the key factor in the selective laser melting. In this thesis the effect of the energy density on the production and process of selective laser melting are studied.
This study is based on the investigation of the real-time monitoring in the selective laser melting. It includes the basic theories and definitions about the selective laser melting mechanism and the interaction of laser beam and material in additive manufacturing. Thus, it is really important to monitor the process in real time to find the defects and all the imperfections during the process.
