This chapter investigates construction applications of natural fibres and fast-growing plant-based materials, which can be processed into load-bearing components using specially tailored digital manufacturing technology. The sourcing and production of the developed sustainable and recyclable freeform lightweight structures based on willow and earth are described in detail and material samples are shown. At the end-of-life, the components can be disjoined and the composite materials in the components can be fully separated mechanically for composting, recycling or incineration. Moreover, the developed structures were prototyped, implemented and tested in full-scale research demonstrators at the 2023 German National Garden Show in Mannheim (BUGA23). With this contribution we show the feasibility of such novel robotic construction methods of biogenic materials in structural applications for the first time. The envisioned application potential lies particularly in the new construction of residential buildings, hotels, office buildings and buildings with similar uses.

摘要

This chapter investigates construction applications of natural fibres and fast-growing plant-based materials, which can be processed into load-bearing components using specially tailored digital manufacturing technology. The sourcing and production of the developed sustainable and recyclable freeform lightweight structures based on willow and earth are described in detail and material samples are shown. At the end-of-life, the components can be disjoined and the composite materials in the components can be fully separated mechanically for composting, recycling or incineration. Moreover, the developed structures were prototyped, implemented and tested in full-scale research demonstrators at the 2023 German National Garden Show in Mannheim (BUGA23). With this contribution we show the feasibility of such novel robotic construction methods of biogenic materials in structural applications for the first time. The envisioned application potential lies particularly in the new construction of residential buildings, hotels, office buildings and buildings with similar uses.
