Recently, the results of the International Exhibition of Inventions of Geneva were announced, and the project "3D concrete printing technologies for prefabricated pedestrian bridge" led by Professor Ma Guowei, Vice President of Hebei University of Technology, won the gold medal. The project, which was jointly completed by Ma Guowei, Wang Li, Zhou Jian and Li Zhijian, fully demonstrates the international influence and leading level of technological innovation in 3D printing for advanced construction at the Hebei University of Technology.

Automation and intelligent construction technologies are urgently needed to innovate and ensure that the construction productivity are in a more sustainable manner. This project proposes 3D concrete printing technologies for pedestrian bridge that integrate BIM virtual simulation technology, 3D printing robotic, adaptive path planning algorithm, high performance concrete, 3D laser scanning technology, Internet of things and health monitoring system, etc. The proposed 3D concrete printing technologies have been successfully applied into one pedestrian bridge that has been certificated by the Guinness World Record and highly praised by many international experts.

The International Exhibition of Inventions of Geneva benefits from the most extensive support and privileges that can be granted to an exhibition. It is under the patronage of the Swiss Federal Government, the State, the City of Geneva and of the World Intellectual Property Organization (WIPO) and International Federation of Inventors Associations (IFIA). This support testifies to the usefulness and quality of the event, now acknowledged as the most important exhibition of inventions anywhere today. It is also the most international, with the participation of more than 50 countries.
