What is additive printing or additive manufacturing?

I have been printing on a 3D printer for six months, and today I heard the term "for the first timeadditive manufacturing". 😅

It turns out that this is the official name of the technology where the object is created gradually, layer by layer, unlike traditional methods of "subtraction of material" (cutting, milling, casting). That is, the printer actually builds the parts out of nothing by adding material rather than cutting it out of the bar.

The term additive manufacturing came into being in the 80's along with the development of industrial 3 D technologies. It highlights the main feature of this approach - adding material, not removing it. Now it covers not only plastic models.

So when we type, we actually do additive manufacturing. Sounds a little more serious than just "3D printing". Although 3D printing seemed difficult for the first month.
