| summary |
This project combines 3D printing and conventional hand-building of unfired clay to leverage each strength in creating custom, zero-waste, reusable formwork. The fabrication method relies on the plasticity and water-solubility of clay in an unfired state to permit the production of larger, more complex clay formwork. This is achieved through the aggregation of 3D-printed units with hand joinery. Since unfired clay possesses limited strength and struggles to hold its weight, shredded paper was introduced. The research first explores the compressive strength of clay with various ratios of added paper. The process of creating paper clay is explained, and its ratios are documented. Next, fabrication case studies at multiple scales are introduced to explore paper clay’s viability as a formwork. The paper clay self-demolds as it dries, shrinks, and falls off the concrete form. This allowed all the clay to be conserved. All clay from the test was rehydrated and recycled to be reused. The fabrication tests demonstrated the effectiveness of the fabrication workflow. The results point to future research that may reduce the embodied carbon emissions of concrete casting through formwork recycling. |
