Welcome back to the lab where we take your questions and turn them into experiments.

And today we're going to get three D printed.

For the past half decade, three D printing has been predicted as the next revolution in manufacturing from jaded A objects to our food to our organs.

Last year, a three D printed here not only stayed alive, but it actually grew.

It works a lot like your printer that prints ink on a page.

But instead of printing one layer as ink, it stacks multiple layers upon each other to build complex structures.

It's like making sliced bread, but in reverse after putting one layer down.

Another is built on top of that and so on until the whole of for bread or your three D printed object is put together.

Three D printing can do a lot of amazing things, including three d printing yourselves in ourselves.

So we're gonna head over to my three d in Toronto to do exactly that.

E Oh, uh, this is what we're gonna be calm.

My 32 uses a structured light through the scanner that works at 16 frames per second and captures two million points of information every second.

It works by projecting a known pattern onto an unknown object in this case, our bodies, and then analyzes the D formation and distortion of that pattern to figure out how far different points are from the scanner by using triangulation.

For example, if we project a known pattern of parallel straight lines onto human body, computers can then calculate what the deformity is and ultimately figure out what the shape of that body is itself.

Immediately, we could see pieces of our three D image on the screen as the program digitally reconstructed the real world us in real time.

Our image is needed to be fully reconstructed and touched up by an artist.

So I went back to actually get our figurines and see some of them come right out of the three D printer.

So here is the final rendering of my three D image before it was printed.

This is called the three D Mesh, and it has looked over for any fragile points that could potentially break in the process.

Like my arm holding the phone textures air, then added on to show what the final image will look like.

Our three D models are gonna be printed on something called Gypsum or polymer clay.

It is laid out and find layer by layer and made hard.

When it is printed with binder and color, the print will take a few hours to complete.

When it's done, the excess powder is and vacuumed out and recycled for future use.

The finishing touches include blowing the remaining powder off, dusting it some more.

A thin layer of glues and applied, which keeps the print hard and makes the colors pop.

Okay, so we've got three friends, so we're gonna go back to the lab, open them up.

We're gonna take a look out for the first time.

I've kind of seen my little finger, but you haven't seen yours.

Let's try it out and see what we look like.

This is gonna be if we were ever to be in a blockbuster way.

I look like I look like more of the rain.

Like that actually feels really like, uh, I love it.

Can, like, see interesting patterns on the fabric that have been, like, chiseled.

Greg's like on his phone as usual detail.

The concept of three D printing is fascinating, and it has so many applications.

There's a long ways to go before I think it come to your home.

But this is happening right now, and so this is really cool.

The agency, obviously for letting us come and get these down there in Toronto, will put links in the description.

 Otherwise we'll see you next time for the next experiment.
