The ‘Stone Spray’ research project developed a device that sprays a mixture containing a binding agent, which solidifies on a surface to create innovative architecture.

‘Stone Spray‘ is a recent research project by Anna Kulik, Inder Shergill, and Petr Novikov in the Institute for Advanced Architecture of Catalonia. The goal was to research the field of additive manufacturing in architecture and propose a new eco-friendly, efficient, and interesting system for printing architecture in 3D.

The group created a robotic 3D printer that collects soil or sand and then sprays it through a nozzle along with a binding agent. This mixture solidifies when it hits a surface, creating pieces of architecture. The shape of the structure is determined by the robot's controller, who can alter its movements using a computer. The robot can even print multi-directionally and on vertical surfaces. You can watch the project video below:
