Robotic 3D Printing Concrete Formwork: Reusable and Recyclable

This project develops computational design models and 3D printing techniques for reusable formwork, enabling the creation of thin-shell, double-sided, and highly detailed building envelopes. One major research contribution is developing a reusable formwork system utilizing binder jet 3D printing technology and casting glass fiber-reinforced concrete (GFRC), resulting in rapid, scalable production with minimal waste. A second novelty of the project is integrating minimal surfaces as a medium for designing GFRC facades through computational design methods. “Minimal surfaces are a great design medium for producing lightweight concrete structures because they can provide structural stability and support while using minimal material; thus, they are highly efficient in terms of material use, as they can distribute loads evenly and minimize the use of concrete” (Mania Meibodi, 2006). This makes them an ideal design medium for creating lightweight, structurally sound, and visually striking concrete structures. The research has significant implications for the construction industry, as it integrates more sustainable ways to design and build enabled by computation and 3d printing technologies.

MinMax was exhibited in Swiss Bau in Basel, Switzerland, published in ACADIA, and has been invited for exhibition in multiple avenues.
