We’ve already heard a lot about 3D printing. But what about 3D faxing?
The technology startup AIO Robotics is planning to create an all-in-one 3D printer, scanner, copier and fax machine.
This seems to be the final step in completely digitizing dental lab procedures. If the clinical or technological circumstances require a technician to fabricate the bridge, denture, partial, space maintainer, or ortho appliance you can send the digital impressions to a lab, have the technician digitally design the appliance, fax it to your office and it will be fabricated by a 3D printer.
In essence you can do this now in a limited way. You can have a remote technician help design a CAD CAM crown and then have it milled on your local machine.
