If I owned a manufacturing company, I would worry about this. Right now, three-dimensional printers are useful for building prototypes, but not much else. Expense is not the problem, of course. If these things can be put to useful work, the prices should drop exponentially. Currently, the printers “print” in many colors, but only one substance at a time. Eventually printers will be built which can print in more than one substance at a time. When that becomes possible, the world will really change.
