Here are seven industry sectors where I think that 3D printing is bringing about, or has the potential to bring, a revolution in the way in which we manufacture and distribute 3-dimensional physical objects:
#1: Automobiles

#2: Construction

#3: Pharmaceuticals

#4: Aerospace

#5: Healthcare and Prosthetics

#6: Manufacturing
It is conceivable that when you place an order via the Amazon website that the item is then produced at the large sheds that were once their vast distribution centers and now become their distribution and manufacturing centers and delivered by drone, of course. The ability to produce anywhere and in any volume may well disrupt the comparative economic advantage that low-cost manufacturing nations, such as China, have enjoyed over the developed world. This is somewhat different from onshoring, because you will not see the same numbers of people employed in vast factories being repatriated, instead there may be scope for small specialist printers for items that cannot be fabricated instore or in the home.
#7: Food

These are just a few areas where the initial ripples of disruption are starting to be felt from 3D printing, but this revolution is not going to be overnight, and my list is by no means meant to be exhaustive, I could quite easily have mentioned the advances being made in other applications, such as entertainment, art, fashion, and jewellery, etc. And if you think the price of replacing your laser print cartridges is exorbitant, just you wait until you are paying for the 3D replacements for your desktop 3D printer!
