A greater invention than the iPad!

3 D printers are devices that slowly build up plastic or other materials to make objects, such as wrenches, guns, medical devices and shoes.  I believe that this technology will take off eventually and replace the iPad, computers and other electronic devices in the home.  There will be great advances in 3 D printing during a time of war because that is when people start to innovate and make things better.

3 D printers can make it easier to build vehicles.  Unlike traditional manufacturing which carves materials away....3 D printing adds through sequential layering of materials without making mistakes.   For right now, 3 D printing unfortunately requires the use of the internet, but you can use digital code for 3 D printing so you don't always need the internet.  It is not recommended that you use the internet for 3 D printing.  The future of 3 D printing will make it so we don't need to have globalization or the internet because we can just build tools and other technologies through the use of 3 D printing.

3 D printing can also be used to make plastic to go around electronic devices and make electronic devices too, such as the phone or radio, televisions or a microwave.  All electronic devices in the future are going to be made by 3 D printers.  You can print in many different textures and also in many different colors.  When the price of 3 D printers come down it will make it easier for people to afford them.

I first found out about 3 D printers when I heard that some people were using 3 D printers to make plastic handguns.  These kinds of guns would not be detected by metal detectors in the airports.  The digital plans have been available for free on the internet and anybody could look at them and download them...and make a gun if they have a 3 D printer!  In the future you will need a license to own a 3 D printer if you want to make a gun or any other weapon.  So 3 D printers are not the problem, it's the people behind them--they are using them for either good or bad purposes.  A plastic gun would be detectable in an X-ray if you knew what to look for.  The military however has an interest in this kind of 3 D printers as well.

3 D printers can also be used in outer space to build moon bases on the moon and on mars and build stuff in outer space to make it easier to build new places for us to explore and live in outer space.  This will eventually happen with the 3 D printer in outer space.  When they make it so a printer can rely on it's own energy source, then that will be another advantage to taking the 3 D printer into space.  And the 3 D printer has has it's own database built into it without having to rely on the internet at all...that will be another great advancement in the future of 3 D printing.
