Even though the broadest range of ideas for cultivation systems in general are being tested, the successful development of technical systems in the medium and long-term has not yet been achieved successfully. Many research questions are still open, which have to be identified and analysed in order to be able to apply them to the development of a suitable system. For this purpose, the developed substrate designs are being tested in regard to their cultivation ability, in that the conceived function models are being applied to physical objects using 3D printing technology and then inoculated.
