We don't actually have a quality assurance module. We check quality in 2 ways:
1) Our computer vision based In-Process Monitoring Module. It monitors whether what is meant to be printed is ACTUALLY being printed and send various alerts (email, text) if that's not the case as well as pausing the print. It is currently available for *some* FDM machines. More info on vision.authentise.com or on the relevant help page.
2) Of course, our MES system is also beginning to allow manual error reporting, Testing result uploads etc. We've built some simple machine learning into this, which should be able to allow us to predict failure in the near future. It is also geared to predicting maintenance needs, though that is not a feature at present.
