I’m not really sure why people think this. Yes, it is a neat technology. However in a modern machine shop just about every tool is computer controlled anyway. Hence every part is made in an automated fashion. The only real difference in question is whether a 3D printer capable of sintering metal will be cheaper than a full set of CNC lathe, milling machine, and drill press.
Excellent point and one I hadn’t really considered. I think that the term “printer” is one that so many can relate to as something that we may have in our homes or offices - whereas a computer controlled lathe - not so much.
The point is that many people do not think they can run a lathe, milling machine, and drill press.
But they all *know* they can run a printer.
This is about the perception of the ease of making magazines catching up to the reality.
