OctoPrint-PrintWatch
PrintWatch uses Artificial Intelligence to monitor your 3D prints for any defects that begin to form. The plugin takes the video feed from any camera compatible with OctoPrint and runs it through a Machine Learning model that detects print defects in real-time. The plugin takes actions set by the user once a failure is positively detected that include:
- 📧 Email/SMS Notification
- ⏸ Pausing/Stopping the print job
- 🔥 Turning off the Extruder Heat
- ⚙ Customized actions created by the user
PrintWatch saves time and material while also giving you peace of mind that your 3D print is printing properly. In addition to detecting defects, PrintWatch has an Anomaly Detection model running in the background that can detect slight changes or anomalies for in your fleet. Get notified early and schedule maintenance for the problematic printer, reducing downtime and costs. PrintWatch's Web App allows you to remotely view and manage all of your printers from anywhere in the world.
