In this study, various analyzes have been carried out in terms of manufacturing time, processes and costs on the additive manufacturing, which has become one of the basic manufacturing methods of the industry. As a result of the processing times and process analysis of the "direct metal laser sintering" (DMLS) method, one of the powder bed fusion technologies, a general cost and process calculation equation has been derived, including the existing equations in the literature, plus all steps of manufacturing and all sorts of calculations. The resulting equation was checked on the sampling Turkey and a study was carried out for the conditions of Turkey. With the developed model, it is made possible to reach the data about the manufacturing time, manufacturing efficiency and effective use of the machine with DMLS parts planned to be manufactured. In addition, amortization calculations and head-to-head analyzes of manufacturing machines were carried out under different operating conditions.
