A robot created at MIT can use 3D printing technology to form an entire building in under 14 hours. The 3D printing system uses a large robotic arm attached to a smaller precision arm. Concrete or spray insulating material can be extruded from the arm.
For this project, we designed a robotic system that's mobile so that it can go on site, gather its own energy through photovoltaics, and gather its own material to carry out fabrication using local materials like compressed earth or even ice. Most importantly, we wanted to make sure that this could integrate into a construction site tomorrow — and would have incredible benefits compared to regular construction techniques.- Steven Keating, engineering graduate involved with the project
This system can make structures faster than other options and it's portable, both of which could make it useful in construction settings.
So far, the machine has been used to 3D print a basic 50-foot diameter, 12-foot high dome.
