Digital photography and inkjets...
While digital photography seems to have matured(I still can't take a decent picture, though... but now I can't blame the camera), inkjets are a different matter...
Sure, some of them now has ink that costs less than high-end perfume, and sure they print pretty pictures... then they start clogging...
Porn industry and 'emerging technology'...
As there are now flexible materials coming on the market, and even dedicated printerheads capable of working with silicone and similar materials... How long until you can print replicas of 'anatomical details' of actors/actresses?
'Ribbed for your pleasure'...
