"3D Printing will never gain broad consumer appeal" The author says that less than 5% of the population will own a 3D printer. I agree with that, but that isn't the interesting bit. What amount of the population will own 3D printed products. I don't need to have my own 3D printer if their is a Kinkos like company that can print items I want (or shops have them printed and I buy from the shop) and have it delivered by drone minutes later. Why would I want the overhead of having a 3D printer? How many people actually have or want to have paper printers today?
