Project period: January 2016-December 2019

This Ph.D. research on 3D concrete printing is focused on overcoming the limitations of the 3DCP process to make it more robust and develop its potential and application in design and construction by keeping the process generic rather than having a more project-based approach to find answers to fixed goals.

With this research, the conventional idea of distinct space and structural element is challenged by creating architectural spaces without any distinctive boundaries between structural elements and architectural elements and focuses on printing complex cellular geometries which can be extended and multiplied across scales and functional domains ranging from structural to architectural elements. While in a conventional building process a considerable amount of material gets wasted from manufacturing to construction, 3DCP research intends to overcome this challenge by maximizing the material usage with minimum or no wastage, without compromising the structural performance of the printed geometry.

Different typologies of cellular geometries across multiple scales are printed and experimented in order to understand the limits of the printer and develop different strategies to improve the printing process.
