But for labs to do it themselves, there IS a workaround! Drs with the new primescan have 1 license they can "give" to a lab - basically they give you their license key, you buy a $100 dongle from Sirona, and you can use Sirona's "Connect Case Center" inbox to view and download Sirona orders from Drs. (this is just to view and download cases, NOT the full inLab design software).
We just implemented this, been waiting for this for years, it's about time Sirona made a way for labs to get STLs without having to pay 20k for a piece of machinery they don't want.
