TED十佳演讲之身体语言 4D打印机的诞生(04)


So remember, I said 4D. So today for the first time, we're unveiling a new project, which is a collaboration with Stratasys, and it's called 4D printing.


The idea behind 4D printing is that you take multi-material 3D printing -- so you can deposit multiple materials -- and you add a new capability, which is transformation,


that right off the bed, the parts can transform from one shape to another shape directly on their own.


And this is like robotics without wires or motors.


So you completely print this part, and it can transform into something else.


We also worked with Autodesk on a software they're developing called Project Cyborg.

我们也和Autodesk(欧特克)合作了他们正在开发的Project Cyborg软件。

And this allows us to simulate this self-assembly behavior and try to optimize which parts are folding when.


But most importantly, we can use this same software for the design of nanoscale self-assembly systems and human scale self-assembly systems.


These are parts being printed with multi-material properties.


Here's the first demonstration. A single strand dipped in water that completely self-folds on its own into the letters M I T. I'm biased.


This is another part, single strand, dipped in a bigger tank that self-folds into a cube, a three-dimensional structure, on its own.


So no human interaction. And we think this is the first time that a program and transformation has been embedded directly into the materials themselves.


And it also might just be the manufacturing technique that allows us to produce more adaptive infrastructure in the future.
