You can make 3-D items that can be very useful

# data[].attributes.body
3d printers are is a process of making three dimensional

# data[].attributes.body
3-d printers are used for a things like cars, or houses, or even sculptures

# data[].attributes.body
I seen a 3D pinter make a house.And they could make the world a great place like print or organs

# data[].attributes.body
3-D printers are used to make tests of the real thing

# data[].attributes.body
You can  make life size things like houses,food,and other things.Also you can things like organs or other things to test on.Also I like trains.

# data[].attributes.body
i learnd that you can make a lot of things with the 3d printer like a golf ball

# data[].attributes.body
3-d printers are for making stuff in plastic and there trying to make human organs but there not able to put in human bodies yet

# data[].attributes.body
you can make alot of things on a 3-d printer

# data[].attributes.body
you can make a golf ball

# data[].attributes.body
I think 3-d printers are very interesting and how they put down layer after layer of plastic. But they are also very useful making parts for bigger things

# data[].attributes.body
I saw the printer printing out a skyline of the empire state building

# data[].attributes.body
I saw the

# data[].attributes.body
i watched the 3d printer build a castle like thing

# data[].attributes.body
I thought it was interesting.

# data[].attributes.body
3d printer are cool

# data[].attributes.body
It was a complex 3-D printer building a skyline of a bi
g city

# data[].attributes.body
A 3D printer is cool cause it can print anythi

# data[].attributes.body
The 3D  printer works by laying down successive layers to create your design.

# data[].attributes.body
it takes i while too make the 3d printed stuff

# data[].attributes.body
Its cool

# data[].attributes.body
its Awesome

# data[].attributes.body
its cool

# data[].attributes.body
3D printing can make organs .....

# data[].attributes.body
3D printers go layer by layer until it makes your object

# data[].attributes.body
A 3-D printer makes thing by layering materials over and over. They can be used for surgeons practicing a surgery so they can make their job faster and easier.

# data[].attributes.body
The 3-D printer can be a useful tool for surgeons because they can practice on artificial organs and arcitecs can make little models of buildings to make theyre job easier.

# data[].attributes.body
The 3D printer heats up the filament and places it in layers starting from the bottom placing upwards

# data[].attributes.body
It takes along time to make something

# data[].attributes.body
3-D printing can be used to make tools in the real world

# data[].attributes.body
That they use melted plastic to make a object and it's very hard for them to print things that are

# data[].attributes.body
11 out of ten would cosinder

# data[].attributes.body
they take a long time

# data[].attributes.body
you can make anything with plastic

# data[].attributes.body
you can be super creative with 3d printers

# data[].attributes.body
A 3-D printer can be used for hospitals, home, and many other things.

# data[].attributes.body
3d printers are useful in everyday life to make tools and on spaceships.

# data[].attributes.body
the 3d printers make objects by making thousands of tiny layers and layering them

# data[].attributes.body
That 3D printers can take a really long time printing something depending on what u are printing

# data[].attributes.body
Most of the time it takes a while to print the object, but it tends to be very exact on the detailing.

# data[].attributes.body
They print stuff Layer by layer so depending on the item it can take a while

# data[].attributes.body
they build using layers and add one on top of another over and over again.

# data[].attributes.body
The printer in the video was very interesting. One important thing is that you don't mess the printer while its printing you'll have to start over. It could help a lot in the real world.

3D Printers can make creative design

# data[].attributes.body
3D printers makes objects by creating layers of plastic or a different material. They can make anything you would like. You can even make hangers.

# data[].attributes.body
3D printers lay down many layers of plastic or whatever material it is using to make something. It can make anything you want it to make and can be useful for making models and prosthetic

# data[].attributes.body
3D printers make objects by creating layers of plastic to create an object. They can make anything that you want. In the real world, they can be used to make body parts for people without legs

# data[].attributes.body
you can use the printer for tools!
and making objects for good uses
or just using it for fun :)

# data[].attributes.body
3d printers can use etal

3d printers can use etal plastic nd others to make an object

3D printers can print almost ever

they help alot

I think that 3-d printers could help the world by helping create thing like if your going to make a building you could use it for blueprints

# data[].attributes.subject

# data[].attributes.body
I think that the world can really benefit from the new technology that is being inviting and sam is the anonymous comment

# data[].attributes.body
I like 3d printers because there cool and ummmmmmmmmmmmm u can do anything with them.

# data[].attributes.body
I think that the plastic is melted and turned in the thing that was programmed.

# data[].attributes.body
I know that 3-D printers use plastic that comes in little rolls, and melts it to put it in layers in the form of it, and we could use it for making tools, body parts, mannequins, and that you need to know the length, width, and height, and occasionally volume if you are making a container.

# data[].attributes.body
i think 3D printers area good and important thing in life they help us make things very easy.
