So we have landed on the moon, people have walked on another planet and we have even landed a rover on Mars, but the 3D printed object recently made in space is a major breakthrough to human kind. LOL
There is something in this that will be of great value and that is 3D printed food. It may sound weird, but the astronauts will be doing a test on food that will be printed in that same 3D printer. Very Star Trekkie!
