Principle Investigator Dr. Richard Buswell of Loughborough University in the UK leads a project to develop a method of 3D printing concrete building components that’s been ongoing for several years. The components could potentially accommodate pre-made services, such as piping or electrical. The project will also enable the production of building geometries not easily done using other techniques by extruding custom designed components for later assembly on building sites.
While we’ve seen some experiments in concrete printing before, this project seems to be doing very well. The project uses a rather gigantic inkjet-like 3D printer that’s specially designed to control a concrete extruder. We can imagine much experimentation on developing the precise concrete mix for optimum extrusion and performance. The printer is capable of printing components up to 2 x 2.5 x 5m in size. Yes, that’s metres! We suspect anything larger would be kinda difficult to move around anyway.
