Winding processes are known from fber composite technology for highly resistance lightweight components for aviation.
These fber-based processes work predominantly with synthetic composites made of carbon or glass fbers. For the construction industry, these additive processes are very promising and resource-efcient building processes, but they are still hardly
used in timber construction despite the very high level of digitalization and technical development. The 3DWoodWind
research project uses a continuous strip of thin veneer as a sustainable alternative as its application material. Its natural fbers
are intact, continuous, and tensile. In the project, three-dimensional winding processes were developed for material-efcient
hollow profle lightweight components made of wood. We describe the material system, composed of suitable combinations
of veneers and adhesives, and develop computational design methods for flament layout and robotic fabrication methods. We
also show an open-source prototype development method, necessary for efcient prototyping. Through several fabrication
case studies, we demonstrate the capabilities of the production process, and investigate suitable architectural applications.
These hollow lightweight components could save large amounts of material in timber construction and serve as a substitute
for concrete or steel components in the future. We conclude by discussing possible applications in the construction industry
and future research possibilities.
