Actually it isn’t 3D printing but the use of a 3D cad cam and then a milling machine to mill the crowns. I am a dental assistant and we make permanent crowns in our office in a 1 1/2 hr appointment.
My dentist uses a 3D mapping wand - akin to a draftsman's CAD system - to make a topographical map of the stub needing a crown, and all adjoining teeth. He emails the data files to a lab in a nearby large city. The finished crown (or partial; this technique appliws to both) arrives by UPS a few days later. My wife and I have had five total crowns and partials done by this method, and every one has been a perfect fit right out of the box.
A year or two ago, I had a crown that needed to be replaced with a new crown. My dentist removed the old crown and used a machine to fashion a new permanent crown while I waited. The whole process took less than 2 hours, as I recall. I suppose it was some type of special 3D printer made especially for dentists, like Barbara said.
Thanks, I'll update
Same day crowns are made everyday with 3d printing

My dentist had one in his office. I came back 3 hours later and it out it in.
Just had one done
My husband is a dentist and he does crowns, everything in office, start to finish in two hours. 👍
yep
