The construction of 3D tissue is an important issue in regenerative medicine. While small 3D tissue has been realized in vitro, large functional 3D tissue has not been achieved due to difficulties in supplying oxygen and nutrients to the tissue. In this paper, we propose automated 3D construction based on hydrogel fiber to produce active 3D tissues. Results of several preliminary experiments in generating suitable hydrogel fibers have resulted in a lattice structure as an example of 3D tissue. In experiments in 3D structure construction, we observed cell growth in the constructed lattice confirming structure functionality.
