BENDING SHELL PAVILION

ROBOTICALLY FABRICATED FLEXIBLE FORM WORK

FOR MINIMAL SCAFFOLDING

2019 | Shanghai, China

Robotic Force Workshop | MIT / ETH/ Tongi University

Team Alexandre Beaudouin-Mackay, Ce Li, Benjamin Hoyle, Molly Mason, Weizhe Gao, Weiran Zhu, Zhe Guo

Instructors Philip Yuan (Tongji University), Philippe Block (ETH)

The Shell Pavilion is result of a 23 day workshop in Shanghai called Robotic Force between Tongji University, ETH, and Massachusetts Institute of Technology. The first half of the workshop used graphic statics to find forms in structural equilibrium with tools like Rhino Vault. These forms were then considered for discretization and fabrication. Using an ABB robotic arm to 3D print plastic, material testing occurred during the design development process to create a design feedback loop where form, material, and geometry effects were considered at both the local and global scale. Our final form was driven by the requirements that we wanted it to fit within a circular baseplate, feel like an enclosure, and have parts that crossed over each other - all of this, using a few parts as possible. To do this we discretized the final form into seven developable strips using a technique that allowed double curvature to be created out of single curvature that appoximated double curvature. We 3D printed these developable panels using the robot and were able to assemble them quickly and without much of the waste that comes with traditional scaffoding. We then applied three layes of brick on top of the plastic scaffolding - once dry, this brick acts in perfect compression and results in an ultra-thin but structurally stable shell structure.
