that can build themselves.
So, this project proposes that
you can have self-assembly at very large scales
This is interesting for construction scenarios
where it’s hard to get to, it’s dangerous
there is extreme environments
it’s hard to get people or machines
or where it’s difficult to build things
in space, under water, etc…
that we could potentially deposit materials
and they could come together to build highly functional things.
In this case it’s a ten-by-ten-by-ten space frame.
When the helium dies you’re left with a large rigid structure.
The other category of research we look at is
How to program physical materials
to change shape and property on demand.
On the top left is our materials and geometry.
That’s the obvious stuff.
Everything we know in the physical world
is made out of materials and geometry.
Each one of those though responds to
different types of energy.
If you have moisture, you might want to use wood.
If you have metal, you might want to use heat to activate it.
And the way that we design the geometry
and how those materials come together
creates mechanical transformation and
allows us to control how it folds, curls, bends or twists.
And we’ve released three materials so far.
The first one is programmable carbon fiber
textiles, and wood.
With wood there’s a long history of using wood
as an active building material.
From Japanese joinery that would use moisture
to make more precise tight joints to contemporary examples.
But there’s two main problems.
One of the problems is that there’s a lot of energy
that goes into forcing plywood to form into arbitrary shapes.
You have to force it and steam it and have molds.
The other is that you are constrained by
the grain direction that you can find in the forest.
So, we print wood, we actually deposit wood
we chop it up into a pulp with sawdust and adhesive or plastics
we’re able to print different grain directions.
Two-dimensional patterns, three-dimensional patterns
that allow it to fold, curl, twist and
go from any one arbitrary shape into any other arbitrary shape.
So, we believe that today we program computers and machines
and tomorrow we’ll program matter itself.
Thank you.
