摘要

The Feature Article in this issue of the Journal of Imaging Science and Technology by Prof. Nakamura and co-workers from Tokyo Medical and Dental University describes ink jet fabrication of three-dimensional structures for biological tissue manufacturing. This approach to using ink jet printing for tissue engineering in particular was initially proposed at IS&Ts Digital Fabrication Conference last September in Anchorage, AK, by Prof. Nakamura, where he stated that ink jet 3D biofabrication will contribute to the development of an innovative approach to direct building up of biological tissues. This technology is a specific application of three-dimensional ink jet printing, another application of which was also described in the previous issue of the Journal in a paper by Profs. Lozo, Stanic and co-workers from the University of Zagreb, in this case in the context of printing plate production. Three-dimensional ink jet printing was actually invented at MIT in the 1990s ,and is currently used primarily as a rapid prototyping technology, as described in an earlier JIST review article. Earlier this year medical researchers at the University of Minnesota created a heart that beats outside the body. They grew the (rat) heart by depositing living cells from a donor animal on a decellularized heart scaffold obtained by removing all cellular matter from a dead heart.
