With FullControl G-code, the FFF printing process can be fully customized. All relevant parameters such as travel distance, extrusion factor and printing speed can be precisely controlled. This flexibility opens up the possibility of using normally undesirable phenomena such as stringing as a targeted design element. In previous projects, flexible, textile-like structures have already been reproduced in this way (see image). Future work will combine this design freedom with the customizability of FFF printing to not only reproduce existing structures, but also to develop completely new scaffolds. The aim of this thesis is to design implantable, flexible and highly porous scaffolds for tissue engineering and to investigate their influence on cell behavior.
