What are the big future technologies?

How far out on the horizon is full arch digital impressions, model printing and full arch appliance (ex. tmj orthotic) 3D printing? I have acquaintances who manage very large labs and are "playing" with this technology, I understand the current costs, which are prohibitive for small, boutique labs.

Apologies if this is an old question as I am new to the Bridge.
