Vacuum compatible 3D printed structures for building engineering applications
Advancements in the field of Digital Fabrication (DFAB)/ Additive Manufacturing (AM) has created opportunities for disruptive innovation in the building engineering sector. The Architecture and Building Systems group at ETH Zurich is using these techniques to create building structures capable of he

This thesis/project is part of a larger effort to develop and quantify the effect of various steps of the DFAB/AM pro-cess, including model geometry, material properties, printing parameters and post-processing methodologies on functional performance. In this project, an FDM 3D printer will be used for rapid-prototyping of small structures (5-20 cm) for testing.

The desired outcome of this thesis/project would be to develop a process to design and print structures capable of withstanding vacuum. The main tasks are:
(1) Assist in setting up an evacuation and charging station (vacuum pump, sealed connectors, physical measurement devices, and digital metering devices and data acquisition hardware).
(2) Develop experiment subset to test the effect of print-ing parameters on high vacuum stability: material, nozzle diameter, environment temperatures, print speed, layer height, infil, etc.
(3) Research and implement post-processing methodologies to further improve the vacuum stability
The experimental results will be published in high-impact scientific journals and conferences and will be used as design input to fabricate full-scale printed structures.
