If you’re using Cerec software(on Dr’s side), you can check this official Dentsply video tutorial. The below explains how to export the file using In-Lab software(on Lab’s side). Thank you.
Step 1
Open the scanned file from In-Lab software. (the screenshot above is from In-Lab SW 18.)
Step 2
Click the button on the top-left corner and open the system menu. In older version, a yellow arrow button will bring up the menu. Then, click “Export”.
Step 3
Type the file name and change the file type by clicking “Save as type” under the file name. Choose “STL-highest resolution” and hit “save”.
step 4
Make sure you have all the files (upper, lower, pre-op, etc.) you need, and you’re ready to send them. :)
