about this project:
with autodesk research we developed a full-scale floor–ceiling system that couples a stay-in-place, particle-bed printed wood–magnesia shell with robotically wound flax reinforcement and a cast geopolymer compression layer. the printed formwork integrates bosses for winding, ribbing, and service conduits; a stress field from the slab analysis drives shell thickness and a single continuous winding path, then the 3 mm flax is impregnated and cast over. the 4 m prototype was printed in 2 h 29 min with about ±3 mm accuracy and proved the end-to-end feasibility at architectural scale, including powder recovery and a clean on-part winding workflow. the result is a lightweight system that eliminates conventional formwork, avoids steel corrosion, reduces waste, and folds structure, acoustics, and services into one element.
