Nozzles used in biological tissue printers could one day be modeled after
a
design that ensures clog-free nozzles
|
We all
have that moment after when we turn from the computer and stare at our
printers, waiting for the countless things that could go wrong in the process
of printing out a document. Inkjet
nozzles can especially be a culprit, as their
tendency to clog costs businesses
and residents alike thousands of dollars a year in wasted ink, not to mention
trips to the barber to fix spots of torn hair.
Jae Wan Kwon, associate professor at the College of Engineering at University of Missouri, has invented an inkjet nozzle with an ingenious method of staying unclogged while keeping solvent; mimicking the human eye.
“The
eye and an ink jet nozzle have a common problem: they must not be allowed
to dry while, simultaneously, they must open. We used biomimicry, the imitation of nature, to solve
human problems.”

The real
potential for a design like this, however, could be the realm of medical
technology, where the US's already innovative market could adopt a model like
this for biomedical labs. Kwon's already
figured this out and inferred to redOrbit that's the direction he'd like to take the
device:
“For
example, biological tissue printers, which may someday be capable of fabricating
replacement organs, squirt out living cells to form biological structures....Those
cells are so expensive that researchers often find it cheaper to replace the nozzles rather
than waste the cells. Clog-free nozzles would eliminate
the costly replacements.”

It's
fascinating how little changes in design for something as taken for granted as
an inkjet could maybe lead to a major contribution to biotech, but that's the
kind of semantic thinking that should be rewarded in the evolving landscape of
American manufacturing.
