More and more publications especially in US use 3d printing technology to create hierarchical tissue constructs. Another example on heart is described in this article. After apparition of fablab, we could see apparition of biolabs in the near future.

Technologies have been rapidly advancing that will enable researchers to fabricate artificial organs. Generally, researchers focus on one technology to create these organs, but now a University of Louisville (UL) research team is bringing many technologies together to create hierarchical tissue constructs that may work better than the originals.
