Kurzbeschreibung (Abstract)
A growing trend in architecture that has impacted building technology, and the architectural landscape is the use of freeform metal panels in façades. However, these cladding panels are mostly handmade, costly, and require high thickness due to structural requirements. To date, architects and engineers are now challenged to integrate aesthetics, strength, sustainability, and circularity into building processes. To overcome these challenges additive manufacture and robotic fabrication can improve sustainability and reduce manual labor. Wire Arc Additive Manufacturing (WAAM) is layer-based, material and process specific, metal 3D printing that is attracting attention in the construction industry due to its cost-effectiveness and efficiency. WAAM can produce single components and reinforced parts reducing material waste and manufacturing time, providing design flexibility and productivity advantages. Although a limited number of projects have addressed the reinforcement of metal plates, there is still a gap in research on lightweight free form steel panels for the Construction Industry, either because the uniqueness of the scanning process to capture and reconstruct the geometry of the metal substrate; the support systems needed across the whole manufacture process or the deformation that thin plates experience in welding. A novel workflow that combines the deformation induced by WAAM and the effect of an elastically pre-bending plate over curved frames is here presented, improving the performance of existing materials and traditional structural elements used in the construction industry.
