Objectives: The aim of this study was to evaluate and compare the internal fit and marginal accuracy of Co-Cr copings fabri cated through CAD-CAM milling and Direct Metal Laser Sintering technology (DMLS) by using stereomicroscope. Methods: A total no of 40 Co-Cr Copings were fabricated and were divided in two groups. Group a: 20 Co-Cr copings fabricated by CAD-CAM. Group B: 20 Co-Cr copings fabricated by DMLS technology. Copings of both group were evaluated and compared for internal fit and marginal accuracy by stereomicroscope. Data obtained was analysed using Statistical package for social sci ences (SPSS v 21.0, IBM). Results: The result of the study showed that the internal fit and marginal accuracy was less in CAD CAM Co-Cr Copings when compared with DMLS technology. Conclusion: It could be concluded from the study that Copings fabricated with CAD-CAM have less discrepancy in internal fit and better marginal accuracy when compared with DMLS Technology.&#13;
