The 2023 6th International Conference on Materials Engineering and Applications (ICMEA 2023) and the 2023 7th International Conference on Manufacturing Technologies (ICMT 2023) were successfully held in Singapore and online on January 13-15, 2023. After the rigorous review process, 28 papers were accepted and included in this conference book. Covered topics include metallic materials, metalworking and mechanical properties, biomedical materials and coatings, solid mechanics and defect identification, materials chemistry and materials application in chemical engineering, preparation and properties of advanced building materials, nanolithography technology and material physics, material forming and mechanical manufacturing. We hope that this edition will serve as an important research source of references and knowledge, which will lead to not only scientific and engineering findings but will also result in new products and technologies.
