**8. Conclusion**

Additive manufacturing has been in practice for decades, yet continuous developments are being carried out due to its complex nature. In this paper, a modeling framework is presented to help understand the physical phenomenon behind the printing technique and correlate the process parameters with generated defects. The framework includes the computer numerical modeling techniques to be used to simulate the macro and micro scale phenomenon of powder bed fusion process. This is designed in a way to identify temperature signatures and anomaly development occurrences to help identify the root causes of defect generation and in a way categorize the optimal process parameters. The next step includes experimental validation of the techniques. This paper contains relevant information on the experimental testing on industrial printing bed. Being in the initial stage of the project, though we have not completed the experimental studies, and we believe any miniature scale

experimentation would not do justice to the presented framework. We expect the context provided in this paper will help research and industry community to improve the state of the art in this field. Industry needs minimum defects and maximum quality with sufficient reliability to be able to flourish in international market. The authors hope this paper would help metal additive manufacturing industry in this matter.
