As the Chair of 2020 7th International Conference on Mechanical, Materials and Manufacturing (ICMMM 2020), I would like to say it is my honor to have been involved with this excellent and exciting conference. Mechanical, materials and manufacturing are three disciplines that are all link directly. A conference that allows this latitude allows for research was success and the edge of knowledge can be pushed fully. This conference was no exception and I would like to thank the prestigious professors that supported the conference and presentations. Many conferences claim to be international, very few are. We would have been in Maryland, just north of Washington DC, but circumstances have made our conference virtual. Nevertheless, we still have internationally spread presenters that justifies saying International.
