Modelling and Processing of the Dynamic Modular Facades Manufactured by the U Bending Technology

Abstract:

This study investigates the possibility of designing and creating dynamic facades of buildings located in aggressive climatic environments (temperatures, air currents, brightness etc.). The study is based on EN AW-5754 samples manufactured by U bending, representing the modules for dynamic facades. The bending process uses a 300 kN Abkant type press. ​ It is performed along two curved lines. The punch and the related mold are printed from ABS with FDM (fused deposited material) technology. Bending is facilitated by customized slots in 4 laser-cut patterns placed along the bending lines. The paper aims to analyze the influence of the slot patterns on the U-bending process, respectively the design of the mold and the punch designed and executed by 3D printing technology.
