Does it actually has to go trough forging and tempering? They don't have a fusing element in the head?

It goes through two additional steps: burning out the plastic and then putting the part into a furnace to get the metal particles to "fuse" together more closely, aka sintering.

The printing part just forms a "green" part, it's basically like you would make pottery, the actual strengthening of the part happens in a high-temperature furnace.
