## 5 Conclusions  
The SLM technique showed an improved coping marginal fit, but high roughness compared with controls. By contrast, the DLP-Cast specimens had smooth surfaces with poor marginal fits. Therefore, the application of additive manufacturing methods (SLM and DLP-Cast) in the fabrication of CoCr metal alloy coping needs further development.
