SUMMARY:A Flexible Mold for Facade Panel Fabrication
DESCRIPTION:Florian Rist (KAUST, TU Wien); Zhecheng Wang (UofT); Davide Pe
 llis (ISTI-CNR); Marco Palma (TU Wien); Daoming Liu (KAUST); Eitan Grinspu
 n (UofT); and Dominik L. Michels (KAUST)\n\nArchitectural surface panellin
 g often requires fabricating molds for panels, a process that can be cost-
 inefficient and material-wasteful when using traditional methods such as C
 NC milling. In this paper, we introduce a novel solution to generating mol
 ds for efficiently fabricating architectural panels. At the core of our me
 thod is a machine that utilizes a deflatable membrane as a flexible mold. 
 By adjusting the deflation level and boundary element positions, the membr
 ane can be reconfigured into various shapes, allowing for mass customizati
 on with significantly lower overhead costs. We devise an efficient algorit
 hm that works in sync with our flexible mold machine that optimizes the pl
 acement of customizable boundary element positions, ensuring the fabricate
 d panel matches the geometry of a given input shape: (1) Using a quadratic
  Weingarten surface arising from a natural assumption on the membrane's st
 ress, we can approximate the initial placement of the boundary element fro
 m the input shape's geometry; (2) we solve the inverse problem with a simu
 lator-in-the-loop optimizer by searching for the optimal placement of boun
 dary curves with sensitivity analysis. We validate our approach by fabrica
 ting baseline panels and a facade with a wide range of curvature profiles,
  providing a detailed numerical analysis on simulation and fabrication, de
 monstrating significant advantages in cost and flexibility.\n\nRegistratio
