Ask the average person on the street what they know about 3D printing, and you’ll find that they’ve maybe heard about the desktop devices that make little widgets. They probably won’t tell you about 3D printing a building.
But, that’s what’s happening in China. The Chinese didn’t put a machine on-site and build the entire building in place. They built components off-site, then assembled them into a building at the location. But, they’re supposedly recycling waste material into the concrete mixture as a binder, which makes it lower cost and environmentally responsible.
There was a Minnesota man who 3D printed a castle in his back yard. His next project was going to be printing a full house. What I think we need to consider is having some government funding into researching projects like this.
