Barcelona’s IAAC (Institute for Advanced Architecture of Catalonia) has teamed with Basque technology company Tecnalia to develop On Site Robotics, a 3D printing construction project in which sustainable, low-cost buildings can be built with 100% natural materials.

On Site Robotics is a new collaborative project which demonstrates how additive manufacturing and robotics can be used in tandem to fabricate sustainable, low-cost buildings that can be built on site with entirely natural materials. It combines ultra-modern robotics practices, such as the use of cable robots and drones, with digital 3D design and 3D printing, and its aim is to bring automation to the construction site along with the real-time monitoring of the construction process.

On Site Robotics’ 3D Printing System was developed specifically for the production of large-scale construction parts made from 100% natural materials. It is capable of 3D printing on construction sites, thanks to a servo-controlled winch system that uses cables to print in a wide range of workspaces.  The 3D printer’s extruder is controlled by Cogiro, a cable-driven parallel robot with automated CNC control that precisely automates the extruder’s movement and allows six degrees of freedom.

These 3D printed construction parts are made of natural, biodegradable, recyclable, and locally sourced materials.

Miniature drones are also programmed to fly autonomously, monitoring the progress of a build using multispectral cameras. They can actually determine the wetness or dryness of a newly printed structure thanks to their thermal imaging capabilities.
