3-D Objects, Just Add Light

[romanbuehler]

can't wait for the moment:

walk into store, buy a box, go home, get rid of my house, unpack box, put sheets on ground, INSTANT HOUSE!

:D

[vobo8998]

im not impressed.

[romanbuehler]

@vobo8998 with a bit of fantasy, you should be able to figure the possibilities... ;)

INSTANT HOUSE OUTTA DI CRATE, YAMMAN! :D

[MinecraftBoyTwo]

MIND = FUCKING BLOWN

[Labratoria]

Cute :]

[Ayevee39]

This reminds me of my childhood. 

[HomoCyborgZombie]

Can a crane be next?

[Darthshepius]

One step closer to making real Weeping Angels ;_;

[thefishtank13]

aliens



[Ne0MT]

what kind of black magic is this!!!

[boingboingdom]

WHAT SORCERY IS THIS

[SeymourDrayton]

Incredible! O_o

[emoticn]

Go pack!!!

[TheWaluigiman1]

SCIENCE

[yurroon]

Nice music!

[sebasgmz]

the color black absorbs more heat so the light burns the black lines so it folds (I guess)

[duke0d0buque]

@sebasgmz The sheets are made of optically transparent, pre-strained polystyrene (also known as Shrinky-Dinks) that shrink in-plane if heated uniformly.

[XbLROUGEx3]

whitch!!!!!!! burn themmmmm



[MrYorkshireFella]

Now that's magic! 

[Famiro]

shape memory materials?

[AndGoProductions]

BURN THE WITCH!

[patilsaurabhr]

Now implement it in manufacturing plant. Untouched manufacturing.

[joujou264]

There is also a metal that can go to its previous form if you have heat hitting it. I've seen this and the metal on a science show a couple of years ago.

[Ryuuken24]

Red cross has been helping Africa over 30 years, and they still live in poverty, and donations keep coming, but no progress has been seen all these years, so where is the money going, are we really solving anything by simply supplying the means for a better life?!

[productionsac]

@Ryuuken24 I could see this being very useful by the Red Cross or other organizations of the like. Say they need plastic containers to store food in safely in Africa...using this method they could send 1000 pre-fab containers in sheets like this overseas for the price that it would cost to send 100 containers that were already formed.

In fact, I don't see how you can claim the usage of this is "for a better life" anyways

[greenbubba]

Try some sunlight and biodegradeable material.

[TJAkiller92]

Go Pack

[Spike116s]

What sorcery is this?!?!

[satanadam]

No it isnt magic its a science

[clemgon]

Does anyone know the name of that piano piece? It reminds me Debussy…

[o0VicSoh0o]

WHAT THE MAGIC???

[coolerow]

THATS A HEAT LAMP!

The black strips are shrinkwraps that compress with heat. I use them all the time. They just adhered shrinkwrap strip to pieces of plastic and added to heat to make them more.

MYTH BUSTED!

[sevensevenification]

@coolerow sure dude.

[Listicath]

@coolerow If you read the website you'll see that the black strips are ink from an printer and they are using an infrared lamp. The ink isn't contracting, it's the plastic beneath the ink that receives more heat, because of the black ink on it.

"Researchers take a pre-stressed plastic sheet and run it through a conventional inkjet printer to print bold black lines on the material. The material is then cut into a desired pattern and placed under an infrared light, such as a heat lamp."

[PridePKS]

@coolerow DESKTOP PRINTER INK god damn it would you ever listen? its infrared heat which heats up the BLACK DARK part of the object and the plastic beneath the BLACK DARK line. that makes the object to contract as much as YOU WANT IT TO.

[pcliveiii]

I GUESS ITS THE HEAT

[o0ShadowsfeaR0o]

Holy cum buckets

[sstteevveenn77]

what ever happened to old fashion scissors and tape?? i feel old...

[lilrobot959]

woah

duuude, give us a demonstration of like

a giant cube.

[LilJoeProductions365]

Origami has never been so easy ;D

[PiefaceclownPrdctns]

Now make a crane!

[sevensevenification]

@Wilforkknowledge: Shut the fuck up buzz killington

[Wilforknowledge]

This concept is not revolutionary. I don't know what the big fuss is about.

[nisreenomarmobayed]

this is awesome

[ciucinciu]

when the pyramid sides touched they exploded into a nuclear blast, thats why they didn t show it

[CloYue]

Magic o.O

[Abnesis]

from 0:30 to 0:41 fail rofl

[BexaRaven]

Is it light or heat causing the effect?

[iRobii]

@BexaRaven Light

[Erde04]

@BexaRaven most likely heat

[FissionTV]

@BexaRaven Its just light. 

[sonodrome]

@BexaRaven Light (electromagnetic radiation) is radiated from the lamp and absorbed by the black lines, this absorption of energy creates heat. So you could say that it's both heat and light that causes this effect.

[Wiseneutron]

@BexaRaven I'm pretty sure it's a photochemical reaction (a reaction that requires light) I heard that some polymers have this kind of reactions

[koko9900]

@BexaRaven light usually generates heat so it should be a heat causing effect.

[dzpharo4life]

@BexaRaven The bold black lines absorb more energy than the rest of the material, causing the plastic to contract

[allepuzigan]

@dzpharo4life The thing is that usually heat adsorption implies expansion, not contraction. Almost every material on earth has a positive temperature ratio, non negative. I think the heat is not the explanation.

[dzpharo4life]

@allepuzigan Not heat, energy, photons carry energy.

[muharraqi55]

great 

[marco171180]

Witchcraft O_O

[Thakrulll]

So they just bend? I though it would be like a optical illusion.

[WaqasRashid]

Did they prestress the plastic on the lines of hinges, so that it was easier to fold than the rest of the material? Or does having black inkjet printing on the shown lines allow more light absorption than the rest of the plastic which is all initially

uniformly prestressed?

[thenewerag]

@WaqasRashid Um I don't think you seen the whole video have you lol... at 0:08 it says pre-stressed polymer sheets and predefined hinges patterned by black ink from a desktop printer.

[Sopkrula]

reminds me of a flower blossoming in slow motion.

[ksoosuru]

this method would be really useful to assemble houses or any type of construction to make it faster, it´s a great idea

[amoose136]

@ksoosuru Especially if your house is made out of shrinky dinks.

[ksoosuru]

@amoose136 hahah, na man i mean in a bigger way like 10000000000000000000000000x the product used in this experiments

[kajicky]

Nice work!
