The Investigation of Temperature Distribution and Thermal Problems in DMLS Additive Manufacturing

In this study, studies on unstable temperature distribution, one of the biggest problems of joint manufacturing, have been evaluated. Heterogeneous temperature distributions, residual stresses and dimensional changes were investigated, which are the most important factors in manufacturing faults. The problems that arise during manufacturing in different types of metal materials have been evaluated in terms of direct metal laser sintering (DMLS) and manufacturing method. The faulty effect of manufacturing parameters has been investigated. Different approaches on pre-manufacturing temperature and error estimation were also discussed with finite element analysis. As a result, what needs to be done to rectify the mistakes is revealed in the light of the available information
