On-Site Robotic Construction

With the aim of revolutionizing the Construction Sector;

This research is an investigative on-site 3D printing of large dimension constructive parts or small buildings using cable-driven robots to reduce manufacturing costs and to realize the customization of the final products.

This is a collaboration between the Institute of Advanced Architecture of Catalonia and Tecnalia, experimenting with the CoGiro, a Cable-Driven Parallel Robot (CDPR)  and LIRMM-CNRS. Its original point of design resides in the way the cables are connected to the frame, called the configuration of the CDPR, which makes it very stable in structure and movement, hence within one week, the team was able to manufacture the largest monolithic piece done within the six month research.

Tecnalia's 8 axis CoGiro Cable-Driven Parallel Robot makes 3D printing in very large work spaces a reality. Moreover the minimal structure of the CoGio is easily assembled due to its servo-controlled winches.

Precedent
The extrusion technology and the material composition are based on the IaaC project Pylos (S. Giannakopoulos, 2015).Initial idea of on-site 3D printing with clay was presented in the IaaC project Fab Clay  (N. Fashami, S. Jokic, S. Naya Lara, 2012)

Material Composition

The material is a soil based mixture with natural additive specially tailored for AM process with an improved tensile strength and viscosity compared to the traditional soil used in construction.

 

Printing Technology

The extruder is composed of a canister with 15 L of capacity for the material, compressed by a pneumatic cylinder. The extruder measures 300x300x2000mm. It allows printing with a layer thickness between 1 and 7 mm, 6 to 30 mm in width, at a speed between 0.05 and 1 m/s.
