The traditional side of the orthodontic lab is a "dusty place", says Tyler Dowdle of Excel Orthodontics. Dentists or orthodontists take impressions or molds, which can be an unpleasant experience for patients. These impressions are sent to the lab with an order for the required device, and the lab manually casts and machines the models, which is time-consuming. However, 3D printers now allow labs to convert intraoral 3D scans into accurate printed models more quickly and with less effort. Excel started transitioning to a digital workflow with their first 3D printer about eight years ago. However, they are now seeking an upgrade because the printers they are currently using come with a high price tag. The manufacturer does not sell their printers but instead leases them for a minimum of $150,000 for three years, after which the customer must return the hardware or start a new lease.
