3-D printers print cars!

3-D printers are making cars!

Vehicles were printed in just two days in Chicago, then New York

The article I read's name was 3-D printers are making cars. In this article it explained how 3-D printers can make cars in only 2 days. I thought that his invention was pretty good but there could be better and more advanced things that people could create wit these 3-D printers and not just cars. These will help us in the future but I thought that they should have created more useful things than just cars with these printers.

These 3-D printers simply do this by an arm moving slowly from the bottom upwards leaving liquids that are usually plastic or metal that quickly (sometimes there are even cells, concrete, or even food!) are turned into either solids or semi-solids. High schools started to use these printers to print their new sculptures or toys and even fingers and body parts. These printers can even help more if you have one in a store they can easily print the device you want to buy for you and then you wouldn't need to go get a new one from a new store. However this may be a disaster to the economy because if everyone has is then no one will have to spend any money and stores will be shut down. The value of money all around the world would go up because everyone would use 3-D printers and people who want to buy things would have to pay extra. Another problem that is going to happen with these printers is that if the money's value goes up then 3-D printer ink would be too expensive to buy. The printer can mostly print all the parts except for some additional parts like the engine and the motor that makes the car move. The designers made those additional parts and attached it to the car.

If I were to compare this article with the last one I did I think this one would help humans in the future more but electric cars are still safe and less polluting. This could create us a worse future but also a better one. It could create pollution but it could also help us find another way to do everything for example if we create a light speed spaceship there is a possibility that it will get destroyed so before we send it out we could print it once or twice so that we have an extra copy. I also think that people can create electric cars and also use the knowledge we know about the electric cars and use that to make less pollution and better use of the materials we have and the knowledge we have.
