A bioreactor and method of forming complex three-dimensional tissue constructs in a single culture chamber. The bioreactor and methods may be used to form multi-phasic tissue constructs having tissue formed from multiple cell types in a single culture chamber. The bioreactor includes at least one translation mechanism to facilitate translation of one or more tissue constructs without direct user intervention, thereby providing a closed, sterile environment for complex tissue fabrication. The bioreactor may be used as a stand-alone device or as part of a large-scale system including many bioreactors. The large-scale system may include a perfusion system to monitor and regulate the tissue culture environment.
