SUMMARY:A Flexible Mold for Facade Panel Fabrication
DESCRIPTION:Technical Papers\n\nFlorian Rist (KAUST, TU Wien); Zhecheng Wa
 ng (UofT); Davide Pellis (ISTI-CNR); Marco Palma (TU Wien); Daoming Liu (K
 AUST); Eitan Grinspun (UofT); and Dominik L. Michels (KAUST)\n\nArchitectu
 ral surface panelling often requires fabricating molds for panels, a proce
 ss that can be cost-inefficient and material-wasteful when using tradition
 al methods such as CNC milling. In this paper, we introduce a novel soluti
 on to generating molds for efficiently fabricating architectural panels. A
 t the core of our method is a machine that utilizes a deflatable membrane 
 as a flexible mold. By adjusting the deflation level and boundary element 
 positions, the membrane can be reconfigured into various shapes, allowing 
 for mass customization with significantly lower overhead costs. We devise 
 an efficient algorithm that works in sync with our flexible mold machine t
 hat optimizes the placement of customizable boundary element positions, en
 suring the fabricated panel matches the geometry of a given input shape: (
 1) Using a quadratic Weingarten surface arising from a natural assumption 
 on the membrane's stress, we can approximate the initial placement of the 
 boundary element from the input shape's geometry; (2) we solve the inverse
  problem with a simulator-in-the-loop optimizer by searching for the optim
 al placement of boundary curves with sensitivity analysis. We validate our
  approach by fabricating baseline panels and a facade with a wide range of
  curvature profiles, providing a detailed numerical analysis on simulation
  and fabrication, demonstrating significant advantages in cost and flexibi
 lity.\n\nRegistration Category: Full Access, Full Access Supporter\n\nLang
