Co-Axial extrusion for biocementation
The project investigates the development of a co-axial extrusion methods for large-scale 3D printing bio-cementation structures. The extruded paste will host microorganisms such as S.Pasteurii, capable of precipitating calcite (MICP) to create bio-concrete structures. A robotic paste 3D printing platform will be used for the fabrication process; the bio-paste will be precipitated and calcified by the bacterial activity reinforcing the material.

Goal
This project aims to optimize the robotic 3D printing systems by developing a co-axial extrusion process. This project will include the following tasks:
Developing, prototyping and testing of the co-axial extruder. Testing the materials in the robotic fabrication set-up.
The experimental work will be carried out in the new bio lab of the ALIVE initiative at HCI - Hönggerberg ETH. A background in mechanical engineering, architecture, robotics, is highly desirable but optional. The student should be motivated, self-driven, and keen to work in a dynamic, interdisciplinary research environment.
