Three-dimensional (3D) bioprinting technology has become a unique system
for tissue regeneration and biosensor development by controlled deposition of bioinks
to produce complex constructs. Different bioprinters including laser-assisted and
extrusion-based have been introduced and used to produce constructs with high
resolution, cell viability and shape fidelity for tissue development. In addition,
microfluidic technology, organ-on-a-chip and electrospinning technology are used to
produce biosensing products to diagnose and monitor living systems. One of the most
critical materials used for bioprinting is bioink. Several bioinks of an advanced level
and different compositions have been developed too. Here, we briefly highlighted
the characteristics, advantages, and disadvantages of some bioprinters and advanced
bioinks that have been developed recently. We also stated some tissue engineering
applications with the use of 3D bioprinting. Lastly, we mentioned a few key areas for
main focus in the future.
