The school has got 3 new 3D printer’s in the fabrication lab. I haven’t used one yet but I have friends that have used it. Max made a tank from a game he plays and it looks really cool. The 3D printers uses plastic and makes the thing you want out of lines of plastic.
3D printers can make moving parts like hinges or wheels. All of this stuff is made out of a type of plastic. People have 3D printed acoustic guitars, flutes, camera lenses, working firearms. You can 3D print a lot of things; anything that you can think of you can 3D print.
