Here is another infograph I have stumbled upon, which really dives into just how far along the exponential curve we are in terms of people buying 3D printers. The infograph compares the growth of the PC market from 1972-present to where we are within the 3D printing market curve. Very interesting, and really shows how how much the market could really grow. Do you think that by 2040 everyone in the US will have a 3D printer just like practically everyone in the US has a PC today? Will it take that long?
