3D printing is a process of making a three-dimensional solid object of virtually any shape from a digital model, using printers and a special plastic material.
There are different software programs to do that. Although it was invented in 1984 , it is now like the mobile revolution- it is expensive to have such a printer at home but soon every house will have one and will use it to manufacture things like toys, decoration, furniture and in few years maybe biological things like our own tomatoes. It sounds now unbelievable but it is undoubtedly will become our reality soon.
This technologically revolution is changing the way the manufactured business works. And it will affect lot of other areas such as medicine, the food production, the toy industry etc. Our kids will not ask us to buy a specific toy, but they will probably say to us: " Mom, dad, please buy me more plastic material for my 3D printer, because I need to manufacture my new designed car toy", which toy will be especially designed by the kid itself!
They say the plastic used for 3D printing is not dangerous, but there are other things governments must consider when apply laws about the uses of 3d printing. It happened to manufacture plastic weapons, witch look just like the real ones and some of them can shoot too.
Except the misuse that some bad people do, this technology can be of a huge help to solve problems of our and the future generation, mostly in the medicine and manufacturing.
Here you can see two interesting videos about this revolution and the use of 3D printers.
