TECH SNAPSHOT
Has Additive Manufacturing (AM) Technology
Reached the End of the Trail?
DR. SCOTT W. BECKWITH, FSAMPE | swbeckwith@aol.com
Remember when " nanotechnology " was a
thing in the late 1990's? Remember the interest
in graphene and additive manufacturing
technology? So, now I'm hearing some of
you say that all three concepts have reached
the end of the proverbial trail. Perhaps you
remember the early days of glass fibers for
the 1950-1960's Polaris socket motor cases.
Or that fibers in critical pressure vessels were
stuffed with high-explosive solid propellant.
Hmmm, well that was just the start because
the next 20-40 years saw even more fibers
become the mainstay even though some were
extremely stiff (and maybe even " brittle " to
some folks). So, what about nanotechnology?
That's smaller than we can see without highpowered
microscopes or scanning electron
microscopes. The technology rapidly became
the topic at conferences even if you could not
see it with ordinary glasses.
SAMPE's symposia and conferences
expanded rapidly with lots of technology
papers. Papers on how to synthesize
nanotechnologies, how to process the stuff, how
to actually make things with " just a pinch " of the
material, and how to expand material structural
properties when used in even small amounts
(yes - very small amounts). Then along comes
graphene technologies and materials often as thin
as an atom. Sort of like trying to make structures
by assembling ultrathin sheets of paper. Graphene
is continuing to find applications today and
technology papers are becoming more frequent.
So, yes, you still see advances and
understanding of what an be done across many
fields employing nanotechnology. In fact, both
nanotechnology and graphene technology are
finding homes within the topics of multifunctional
materials applications. From a SAMPE viewpoint,
technologies associated with high strength/high
stiffness fibers continue to draw very high interest
across many technologies and interests. So do
material aspects much smaller than 5-8 micron
(carbon, graphite fibers) such as nanotechnology
