Robotically winded full scale timber prototypes

Abstract

Additive manufacturing is a promising and resource-efficient construction method, applying material only where needed. Demand for these processes in construction is growing, but research into their use in timber construction is limited. The 3DWoodWind project explores additive application methods using thin wood veneer strips. Robotic winding processes can be used to develop wood-based hollow parts with minimal material input and optimised structural properties. This paper presents a modular building system of robotically wound column and slab components, including a brief description of the structural design and material system, with a focus on the manufacturing process. It covers in detail robotic fabrication, customised end-effector design, formwork system development, computational design methods, and the integration of a fully automated adhesive application system. A full-scale prototype roof structure demonstrates the manufacturing process and reusability concept in various architectural applications. The paper concludes by discussing the building system's potential and areas for further research.
