AI Failure Detection in SimplyPrint

Introduction

AI Failure Detection in SimplyPrint watches your printer's camera feed while a print is running and looks for spaghetti, warping, and blobbing. It can notify you when it detects a likely failure, helping you stop wasted print time and filament.

How AI Failure Detection works

When enabled, SimplyPrint analyzes images from your printer's camera during a print and builds a confidence score over time. If that score crosses your chosen threshold, SimplyPrint can notify you. On the Basic plan and higher, you can also configure it to pause or cancel the print automatically.

Privacy and AI training

Sharing data to help train and improve AI Failure Detection is optional. Read what is shared, how training works, and how to change the setting.

Included time and paid licenses

Every standard SimplyPrint plan includes 12 hours of AI Failure Detection per account each month. This is one shared allowance across all printers on the account, not 12 hours per printer. Unused included time does not roll over to the next month.

The included 12-hour pool monitors one printer at a time. Each paid license adds one simultaneous, time-unlimited monitored printer.

For monitoring without a monthly time limit, you can add paid AI Failure Detection licenses on every standard plan, including Free.

• One paid license monitors one printer at a time without a time limit.
• You can move a license from one printer to another.
• If you monitor multiple printers at the same time, each one needs an available license after the shared 12-hour allowance is used.
• License prices and the maximum number available depend on your plan and billing currency.

See the live prices and per-plan limits in the SimplyPrint pricing comparison.

Available detections

The AI can currently detect:

• Spaghetti (failed extrusion)
• Warping (print lifting off the bed)
• Blobbing (large blobs of filament)

Enable AI Failure Detection

1. Go to the printer in the SimplyPrint Control Panel: simplyprint.io/panel (web) or in the app.
2. If you have multiple printers, click on the desired printer.
3. Locate the AI Failure Detection widget below the camera.

Notifications

Push and email alerts are available on every plan. SMS alerts are available on Pro, Print Farm, School, and Enterprise plans.

• Mobile push notifications:
• • Android
  • iOS
• Email
• SMS/Text on Pro and higher (no image included)

Settings and automatic actions

You can configure AI settings per printer or apply them to your entire account.

Basic and advanced mode

• Basic Mode: One set of settings for all detection types.
• Advanced Mode: Customize settings for each detection type individually.

Available settings

Sensitivity: Choose how confident the AI must be before triggering an alert:

• Low, Medium, High, or Very High.

Sensitivity controls how quickly the AI becomes confident that a failure is happening.
The AI builds an "overall score" based on multiple detections over time.

Low sensitivity = The AI needs more time and more detections to be sure. The score grows slowly.
High sensitivity = The AI reacts faster, needing fewer detections. The score grows quickly.

• Actions:
• • Enable/Disable notifications (push, email, or SMS).
  • Print actions (available on the Basic plan and higher):
  • • Cancel print automatically (irreversible).
    • Pause print:
    • • Cool hotend (prevent oozing & save power).
      • Retract filament (default: 10mm).
      • Lift extruder (default: 10mm).

Warping example

For warping, set higher sensitivity to get notified faster. Warping may not always mean a failed print - adjusting the bed temperature or securing the print may save it. Read the guide to fixing warping.

Review AI activity

Print history

• AI activity is shown on each print job.
• If AI triggered an action (alert, pause, or cancel), it will be logged.
• Users can rate detections as good or bad.

Statistics page (Pro and higher)

• See total money saved by AI-detected failed prints.
• The estimate uses the calculated cost of prints that were canceled, or had objects skipped, after an AI alert or pause.
