Advanced manufacturing technologies are among the strategic themes which would support various industrial sectors in Thailand, including automotive, aerospace, and medical. The combination of the successful development of the advanced manufacturing and the knowledge transfer to the local industries are the key factor which would lead to the sustainable growth of Thailand’s economy. 3d-printing and Metal Matrix Composites are among technologically emerging areas which will play the vital role in the manufacturing of high-valued and high-performance components in a foreseeable future. Nonetheless, the R&D and adoption of these technologies are at the premature stage, and many infrastructures are still lacking in Thailand. As a result, the potential impact of these technologies is hardly realized. Therefore, the present proposal aims to illustrate the development of the laser-based 3d-printing of metal matrix composites through the experiment and numerical modeling. The primary purposes of the present proposal are two-folds. Firstly, we would like to demonstrate the potential impact of the 3d-printing of metal matrix composites by leveraging the facilities and experimental expertise from our international partner, Joining and Welding Research Institute (JWRU), Osaka University. Secondly, we will develop the first principles based and data-driven modeling to accelerate the material development process. Upon the completion of this proposal, the capability of the 3d-printing to fabricate MMC materials will be demonstrated, in which such demonstration has rarely been done due to the technical difficulty. In addition, we will establish the integrative framework between the fist principle and data-driven calculation which could be used to assist the material development. A successful demonstration of the numerical framework could be beneficial for other material systems since the same framework can potentially be adopted. The success of this joint project could serve as a good initiative for multi-disciplinary research team from material science, data science, and thermal science. In a short term, the results of this collaboration would lead to scientific works worthy of the publication in high impact journals. It will also promote knowledge sharing between research teams as well as individuals who share the same technological interest. A jointly developed research proposal for a more competitive grant program such as Newton Fund and e-Asia can also be expected. Nonetheless, a long-term impact from this initiative collaboration could be much more substantial. Figure 1 illustrates the potential 7-years roadmap where the research in the 3d-printing of MMC materials can be carried on from building fundamental understanding to being established as the promising advanced manufacturing technique for both Thailand and Japan local industries. Ultimately, both academia and industries in Thailand will mutually benefit from sustainable collaboration from institutes in this collaborative joint program.
