PrintCanary
Watch your 3D prints fail before they waste your filament
PrintCanary watches your 3D printer via webcam and emails you the moment a print fails. No app, no OctoPrint, no Raspberry Pi. Open a browser, allow camera access, and walk away. Works with any printer. Free to start.
I'm Curtis, a third-year ICT engineering student in Oulu, Finland, and I built PrintCanary because I kept walking into the FabLab to find prints that had failed hours ago.
The problem: 3D prints fail silently. The printer keeps extruding plastic into thin air for 12 hours while you're asleep or in class. Everyone who prints has that one memory of walking in to find a spaghetti mess.
Existing tools like Obico are great, but they require OctoPrint, a Raspberry Pi, and 45 minutes of setup. Most people never get that far.
PrintCanary is different: open a browser, allow camera access, point it at your printer, walk away. If something goes wrong, you get an email. That's the entire setup.
It uses Twelve Labs' video AI to analyse your webcam feed, so it catches failures that narrow CV models miss, including ones it's never been explicitly trained on.
Free to start. No app. No hardware. Any printer.
I'd love brutal honest feedback, especially from:
Anyone who's lost filament to an undetected failure
FabLab or makerspace staff managing multiple printers
Anyone who tried Obico and gave up on the setup
What's working? What's broken? What would make you actually use this?
