Impossible architectures: 4D printed spacecraft | Raul Polit-Casillas | TEDxManhattanBeach


if you could imagine it someone else
will be able to build it that was a
quote from Walt Disney with a fashion
designer mother in an engraver artisan
engineer father I grew up in a very
creative environment and since I was a
kid I would have could ambition a new
toy a new device of some sort based on
what was gonna be my next adventure and
I’ll try to build it using anything I
could get my hands on from Lego parts to
disassemble toys I used to own so I was
four and I wanted to build a spaceship
to sit in and watch my favorite TV show
cosmos baikal saggin because when you’re
watching a TV show that explores the
universe it’s much better if you have
your own spaceship right so luckily for
me my parents had just bought a new
refrigerator and the cardboard box it
came in it was perfect to do to do this
so the day before in the middle of the
living room
and under my mom’s technical supervision
my diner I started sketching on the
walls carrying doors windows and using
parts of my other toys to make knobs
handles propulsion systems anything that
was needed to make that spacecraft look
like the real thing I even have one of
those little chairs that I turn into
like a proper spineless chair right but
the bottom line is when that they’re in
complexity they’re in the impossible and
designed to go beyond hoping not only
for something faster better and cheaper
but greater it’s part of humankind’s
intellectual DNA we humans have designed
and built our way out of caverns by
facing many challenges and we have we
come so far we have used our creativity
to design everything that’s around here
today
housing construction clothing cooking
methods tools everything the reality is
every time we break through one of those
barriers one of those impassable
barriers our life gets more complicated
and soon we wish for something else
maybe a new phone will allow me to
capture reality in a much better way a
new house to live a new dream and even
spacecraft to reach them reachable in
essence design among many other things
is always driven by hope for something
we didn’t have before if you’re in the
business so
dealing with Impossibles there are many
things you have to do but the first of
all is to create a vision a
multidisciplinary vision in a way of
working there a way to get there during
the Renaissance
created the studio’s called Italia’s
spread out all across Europe in those
studios and master artists engineer or
architect work with students and
apprentices to make one of unique art
pieces that will push the let the the
state of the art of the craft in those
studios it was not only important the
challenge they were tackling it was also
how to do it it’s kind of like the
saying about the journey and the
destination the both important were you
dealing with Impossibles
so as relevant as their style it was
their technique and that marriage
between the what and the how led to a
lot of innovation during that time a
couple years ago I have a chance to
bring this concept of Atelier to the Jet
Propulsion Laboratory
today’s JPL satalia it’s a
multidisciplinary design studio where we
tackle some of our most complex problems
my co-founders and I work really hard to
create an environment where we can
mature new concepts infuse new
technologies and bring as many
innovative methods as we can to improve
the communications between ourselves to
help each other pushing the limits of
how we think and most importantly to
have fun at Sylvia has been very
successful in the last two years we’ve
tackled eight main challenges and we
were able with a great team to make it
happen in a way that with very very
thorough engineering analysis we were
able to very quickly produce highly
detailed designs that we can 3d print
today but as I said life gets
complicated and often embracing new
technologies or new methods it’s part of
their business 3d printing or additive
manufacturing as we engineers like to
call it it’s one of those fields that is
opening up the path for innovation in 3d
printing today you can pretty much play
with any design you want you can use
different materials and combine
different techniques and complexity any
complexity is becoming more or less more
and more a commodity
a couple years ago my team and I had a
challenge could we design a system
capable of enabling large surfaces in
space adapt to any shape and be able to
be built in space so we use the Italia
approach to tackle the problem and soon
two questions arose could we make this
simpler and two could we make the system
multifunctional so after some work we
realize that perhaps textiles might be
the path to follow and 3d printing the
technology to simplify the process and
here’s the result a multifunctional 3d
printed metal fabric capable of
performing four different functions
first of all it can it can fold in any
way and therefore adapt to pretty much
any shape second it can hold a tension
if you stretch it it will resist third
it reflects the light as you can see
here in the video and fourth on the back
of it it actually works as a thermal
radiator as an energy radiator and this
is as it comes from a three printer so
using 3d printing allow us to make
something impossible possible but at the
same time open it up a path for us to be
even more innovative so let me introduce
you to space 4d printing nowadays in the
in the aerospace business there is a new
trend cube sets these are a smaller
spacecraft you can hold with your hand
and they’re used by universities to
perform different functions in a space
at a reduced cost
this little bezels have everything you
want propulsion systems attitude control
solar panels imaging sensors anything
within that context I started leading
our technology development effort as JPL
a year and a half ago to aim towards a
new type of architecture for small
spacecraft and we call the 40 printed
spacecraft and here’s a deal a big
percentage of all the structural mass of
any mechanical system that goes into a
space is there because it has to
withstand the forces during lunch now
all they shake it in the rocket we have
to do something with it right but once
the system is in space we don’t need
that material anymore
hence we start asking ourselves could we
do something else with it maybe we can
help
transferring power maybe we can do
who held the thermo maybe we can do
science with it so our first attempt to
design a forty printed spacecraft was
done in a 10 by 10 by 10 centimeters
cube we designed and built four modules
that will perform four different
functions capable of being in pretty
much any spacecraft you can see today so
first we design a power module that
integrates cables wires connections
all-in-one metal component that also
surface sexual component we also have 3d
printed and tested Springs capable of
deploying components once the system is
in space third we design and and and
printed passive thermal management
systems capable of also performing as as
a structural component so a honeycomb 3d
printer honeycomb panel that you can see
in black in the image or a dual material
do a metal panel capable of reflecting
the light in Vida on one direction while
its it acts as a thermal radiator on the
other direction and of course we build
an optimized general structure that will
hold everything together and this was
our first iteration but then the
question came again could we do more
with less
could we go beyond and yes we could and
here’s the second generation we
integrated all those four functions into
one single component and this is as it
comes from the 3d printer what is truly
dramatic here is that this could make
traditional assembly design obsolete we
foresee a future where we can
potentially 3d print the whole
spacecraft this way but for now during
this first pioneering steps we just
trying to make sure that everything
performs well that everything is
optimized and could do more than one
function but then again
could we go beyond could we go further
and we can and we did and doing our
third generation now here’s a component
of it we were able to get a bigger size
more complex and integrate all those
four functions and even even more
functions such as radiation shielding
the question is if we keep going forward
yes we will we will add JPL and we will
as a species because humans will always
be inventing new things there are plenty
challenges for you and me to tackle out
there the key is
that we inspire and we encourage each
other especially young generations to
make them think like that artists in the
in the in the Atelier create a joint
vision with your team embrace new
perspectives and new technologies make
sure that you enjoy the journey and the
suffering of developing something new
because I guarantee you there’s a lot of
suffering and also there yourself to
push the limits to go beyond and nurture
yourself and your team but also future
generations because impossible things
could be possible in space and on earth
as long as we keep connecting things
that were not connected before and as
long as we keep our feet on the ground
and our head in the stars thank you very
much
