Additive Manufactured Facade, ETH Zurich, 2019-2023
PhD research project
Facades are essential elements in architecture, both from a design perspective but also for their energetic impact. Their primary role is to secure user comfort and protection from the outside. Nowadays, facade designs use novel technologies to increase environmental performance and reduce Co2 emissions. Additive manufacturing addresses these challenges and encompasses the potential of a mono-material prototype, easy to recycle and customized to user requirements.

This PhD project is a part of a collaborative project with the Chair of Architecture and Building Systems and the Chair for Digital Building Technologies at ETH Zurich as part of the NCCR Digital Fabrication. The collaboration aims to identify whether a thermoplastic mono-material performant facade can be additively manufactured. The research focuses on developing performative geometries that respond to multiple environmental parameters, such as daylight, shading, structural strength, air permeability, water tightness, and fire protection. Each one of these environmental parameters is tested in a standardized facade test rig, to achieve the fabrication of an integrated mono-material element. The novel process wants to enable the design and additive manufacturing of energy-performant facades to reduce carbon emissions and waste in the building industry.
