The 3D Printer- Printing paper is not the only things printers can do

This really blew my mind. There will be all types of things printers will be able to print. All you will need to do is to scan what you want to be printed! In this video, it shows how a wrench is printed from a 3D printer. That is pretty awesome. It’ll save lots of time and effort. The invention can scan anything and reprint it. Can you think of all the applications that can be used? What if someone makes a huge 3D printer that could print out buildings or houses. Human labor will be reduced all around the world. If you lose something, you could just reprint it.

If you are still interest in a 3D printer, then watch this! This shows a 3D printer that can print out a human kidney! If we prefect this innovation, then many lives will be able to be saved. We will be able to print out any organs that we need.
