Want to 3D-Print a Kidney? Start by Thinking Small

Scientists led by the Stevens Institute of Technology's Robert Chang have developed microfludic-enabled three-dimensional (3D) printing of organs.

Said Chang, "We're operating at the scale of human cells, and that lets us print structures that mimic the biological features we're trying to replicate."

Microfluidics also facilitates interchangeable use of multiple bio-inks within a single printed structure, an important consideration as complex organs require precise combinations of different cell types.

Chang's colleagues produced a computational model of a microfluidic printing head, in order to modify settings and predict bio-printing outcomes without requiring real-world experimentation.

"Our computational model advances a formulaic extraction that can be used to predict the various geometrical parameters of the fabricated structures extruded from the microfluidic channels," said Stevens' Ahmadreza Zaei.
