- I'm Reza Moini, I'm pursuing my PhD
in civil engineering at Purdue University.
3D printing allows you to incorporate
various design concepts and
so therefore it allows you
to fabricate elements with
a specific architecture.
However, one weakness
is that layer-by-layer
printing process typically
involves formation
of internal flaws and non-uniformities
in the micro-structure of the material.
What's novel about our work
is that using 3D printing
we incorporate bio-inspired
architectures that provide
resilience, flaw-tolerance,
and fracture-resistance
to a material that's
intrinsically brittle.
We've looked into a variety
of design architectures
such as compliant design,
honeycomb architecture,
auxetic architecture,
trying to specifically
Bouligand architecture.
These architectures can bring in specific
performance characteristics,
enhance the properties
without sacrificing the strength compared
to conventionally-cast man-made materials.
Even the direction that the 3D
printing technology is taking
I hope that we can learn
from these architectures
and look into new ways of designing
the materials and the
structures for future.
