Abstract

The interest in 3D printed earthen buildings in developed countries has increased due to the demand for healthy, comfortable and sustainable buildings constructed with low carbon materials and laboursaving methods. However, the amount of research about this field is still limited. Our research aims to contribute to this field by optimising the robotic 3D printing process by investigating issues such as buckling while printing, adequate soil mix recipe for printing, print and extrusion speed calibration. This paper illustrates the process and the results of the temporary research project and the Robotic Cob Printing Workshop with MSc Computational Methods in Architecture (CMA) students at the Welsh School of Architecture, Cardiff University, in March 2022. The project aims to achieve structural stability with less material by using the geometry and the infill of the building block while exploring the role of computational design, robotic extrusion and material understanding in robotic 3D printing with earth as a low-carbon novel building method.
