| summary |
‘BioMatters’ explores methods of creating wood-based material for 3D Printing freeform concrete formwork. The concrete industry is widely acknowledged as a significant contributor to waste, pollution, and resource consumption. Typical concrete formwork, which constitutes 40% of the overall expenses in concrete construction, is a significant source of waste. Recent 3D printing advancements in concrete formwork offer increased design flexibility, significantly reduced concrete consumption, minimal material waste, and improved productivity. This research project represents a pioneering advancement in 3D printing formwork by investigating robotic 3D printing methods with wood-based materials that are fully biodegradable, reusable, and recyclable. The paper presents a novel method of coupling robotic 3D printing of wood-based material with incremental set-on-demand concrete casting to create zero-waste, freeform concrete structures. Here, the concrete takes its shape from the 3D-printed wood formwork and, at the same time, concrete stabilizes the 3D printed wood to prevent its deformation on a larger scale. Once the concrete is cured, the formwork is removed and is fully recycled by grinding and rehydrating the material with water, thus creating a nearly zero-waste formwork solution. The method is investigated involving the design and fabrication of a pair of 1.8-meter-high structural columns. This project focuses on utilizing the material from previous 3D printed formwork for each subsequent column, to evaluate the reusability of the material. The project explores various aspects, including sequential rebar integration, the correlation between the geometric properties of the 3D printed formwork, and the rheology hydrostatic pressure of the concrete mix in relation to material design. |
