Self-supporting Lamellae is a prototype that demonstrates the potential of 3D Concrete Printing (3DCP) in producing lightweight structural components with high efficiency and minimal manual intervention. Inspired by the branching patterns of mushroom lamellae, the design introduces rib-like folds on the column-slab system. These ribs enhance the structure’s self-supporting capacity during printing and are also structurally informed to integrate the reinforcement system and improve overall performance.

Both the slab and the column can be printed monolithically, eliminating the need for custom formwork, temporary support, tailored substrates, or segmentation. As a result, the system is well-suited to the fast production demands of the construction industry while preserving the benefits of customization and material efficiency enabled by 3DCP technology.

This lamella-based structural system offers a rapid, low-cost, and construction-ready solution for the paradigm of “print structure only” in large-scale 3DCP. It holds potential for prefabricated multi-story buildings, providing an alternative to 3D-printed masonry walls and opening up new design opportunities for automated construction.

The prototype demonstrates a fabrication strategy for integrating inter-layer reinforcement during the 3D Concrete Printing (3DCP) process, as well as straight reinforcement placed in vertically aligned channels along the outer shell of concrete columns. It represents a significant step forward in the practical application of reinforced 3DCP, with key advancements in material compatibility, design-to-fabrication workflows, and coordinated multi-robot production. An adaptation of this fabrication strategy is employed in the structural system of Tor Alva.

By incorporating features such as thin shells and hollow cross-sections, the system enables material-efficient structural solutions.

This column section embodies a sustainability approach for concrete construction—one that balances performance, minimal material use, and craftsmanship. It highlights the potential of using concrete more responsibly, where each printed component is purposeful, whether in load-bearing capacity, embedded functionality, or aesthetics.
