Agrian Yiu, a graduate student from the Bartlett School of Architecture, has created a conceptual project that plans to utilize 3D printing technology to help reconstruct a quarry in one of Brazil’s oldest favelas, Morro da Providencia. The project will aim to revitalize the local quarry into an enterprise zone for the local community, with an initial design that includes social spaces, offices for the quarry's managers, workshops for processing stone, and even an open-air museum. The project aims to process the dust produced while quarrying into a 3D printing material. This would allow stone drainage elements to be 3D printed from the very material found in the quarry, and would help redirect rainwater.
