I am a big follower of 3D printing. I predict 3D will take off like blockchain did this year in about 18 months. 2020 is when the technology should be ready for prime time.

Over the next 10 years, we will see manufacturing streamlined with a lot of steps eliminated. People do not realize they will order someone online, that order will be sent to a local fulfillment house that prints it out and wil be delivered, most likely by drone.

The entire process will be automated with no people involved. Of course payments, since it is automated, will have to be digitized and blockchain will ensure all parties are aware of what was paid.

You are right, it is a match made in heaven. We should also see many machine learning projects tied into blockchain.
