Egg Shell Pavilion - ultra thin printed formwork

In the second 11-week module of the second trimester of the MAS ETH in Architecture and Digital Fabrication, we will explore the application of ultra thin printed formwork for concrete to create a pavilion structure.

Based on ongoing research of of the MAS ETH in Architecture and Digital Fabrication will fabricate a concrete 4 column and canopy pavilion. The objective of the course is to explore simultaneous process of printing and casting,   reinforcement and structural optimization for both columns and wood elements as well as usage of low-carbon concrete.


Eggshell is a novel fabrication process for the creation of non-standard, reinforced concrete structures. The process exploits the controlled hydration of concrete as developed in Smart Dynamic Casting. By carefully controlling the early age strength gain of the concrete, 3D-printed recyclable formworks can be used for the casting of full scale, concrete building elements.


Through the project, students will be applying how design workflows in computational design tools as well as digital fabrication technologies can be used to create an architectural space.
