I am being proven right.
It will, but I think people should broaden their view a bit - 3D printing with plastics is just a very, very, very small part of the overall “additive manufacturing” revolution that is coming upon us.
Additive machining/manufacturing is going to revolutionize manufacturing and substantially lower per-unit costs. Now, instead of dragging in a huge block of material “X” and machining away 80+% of it into scrap, you’re going to have raw input material and you’re going to use only what you need.
Further, your need for tooling is going to go way down, as well as the cost for workholding devices (like vises, trunnions, clamps, tombstones, etc). All that stuff in a modern CNC shop costs big bucks and adds to the cost of equipment.
Yes, and it might make the argument over gun control a moot point. What if everyone could print their own guns? How would the government control that or register any firearms? We live in interesting times.
