The MicroG-3DBP project, which is funded by the Federal Ministry of Economics and Climate Action (BMWK), aims to create an advanced ground-based simulation platform for 3D-bioprinting in microgravity. Unlike current methods for generating microgravity, such as drop towers or parabolic flights, this innovative platform allows for extended observation periods essential for a comprehensive analysis of 3D-bioprinting processes. Hydrogels, bioink, and cell spheroids can interact and be continuously studied over several minutes, hours, or even days.
The overarching goal is not only to simulate microgravity, but also to adjust gravity levels as required. For example, the focus is also on simulating gravity levels similar to those of Mars, the moon, or the low earth orbit. The development is being carried out in close collaboration with the German and European Space Agency (DLR and ESA). In the future, the platform, supported by artificial intelligence, we be used to validate experiments that are to be carried out on the International Space Station ISS or possible successors. The platform will not only be used to test the feasibility of experiments and to optimize printing parameters but will also help to save valuable astronaut time and the associated costs.
