People ask me if and when 3D printing will become a method of mass production. As far as plastics go, I don’t know. For metals, though, it is a whole different story: it is already happening. Metal 3D-printing technologies are evolving at breakneck speed, constantly incrementing their size and velocity capabilities. One of the reasons for this, in my opinion, is the intense competition, both between different technologies and different approaches to the same technology. This is not, however, the only reason.
