here as a way to say, 'Hey, this is something
you could do, too,' " Butts said.
" We're trying to integrate research
into student careers at an early point, "
said Sierros. " We have a student subgroup
that's purely hardware and they
make the 3D printers. We have students
leading materials development, automation,
data analysis. The undergraduates
who have been doing this work with the
support of two very competitive NASA
grants are participating in the whole research
process. They have published
peer-reviewed scientific articles and presented
at conferences. "

Using Lasers to 'Heat and Beat' 3D-Printed Steel to Help
Reduce Costs
A new method for 3D printing metal could help reduce costs and make more efficient use of
resources.
University of Cambridge, United Kingdom
A
new ethod for metal 3D printing aims
to make more efficient use of resources
by allowing structural modifications to
be " programmed " into metal alloys during
3D printing, fine-tuning their properties
without the " heating and beating " process
that's been in use for thousands of years.
The new method combines the best
qualities of both worlds: the complex
shapes that 3D printing makes possible,
and the ability to engineer the structure
and properties of metals that traditional
methods allow. The results are reported in
the journal Nature Communications.
" There's a lot of promise around 3D
printing, but it's still not in wide use in industry,
mostly because of high production
costs, " said Research Lead Matteo Seita.
" One of the main drivers of these costs is
the amount of tweaking that materials
need after production. "
" The reason why heating and beating is
so effective is because it changes the internal
structure of the material, allowing control
over its properties, " said Seita. " That's
why it's still in use after thousands of years. "
One of the major downsides of current
3D-printing techniques is an inability to
control the internal structure in the same
way, which is why so much post-production
alteration is required.
" We're trying to come up with ways to
restore some of that structural engineering
capability without the need for heating
and beating, which would in turn
help reduce costs, " said Seita. " If you can
