3d printing

People in the world never thought we were able to customize things on a computer and have a machine print it out in small plastic strips. the 3d printer was something many never believed in. Now we are making cars, guns, and things that even help humans.

The 3d printer now is such a great invention that has been improved over the years its been created. it all started with a small 3d printer probably about a 5x5. Today many printers are big enough for cars but it takes a long time.

Next will have them go faster since they are already a big enough size for plastic cars. Thats probably a thing they will improve next. People now believe that the 3d printer is possible after it was created. They have been proved wrong.

25 useless technology inventions

http://list25.com/25-most-useless-inventions-ever/2/

All of these inventions are very pointless. Most of these basically are for lazy people. such as a portable chin rest and control alt delete wand.
     Most of these inventions are in japan. I do not know why anyone would buy these items. They should just sell they company that made them.
     The most worthless item here is diet water because water has nothing in it in the first place. Im wondering if they added healthy minerals in it. they did not realize water is already healthy and have nothing in it.
