Reliable filament monitoring during 3D printing

Snapmaker Filament Runout Sensor Kit for U1 is an original service kit designed to replace the filament sensor inside the extrusion unit of the Snapmaker U1 printer. The sensor continuously monitors the material feeding status and helps detect filament runout, jamming, or an interruption in the flow in time.

When a problem is detected, the printer automatically pauses the print and saves its current progress. Once the cause has been resolved, you can continue without having to restart the entire print job. This is particularly practical for long projects and printing without constant supervision.

Main benefits

• Real-time filament feeding monitoring
• Detection of material runout and feeding problems
• Automatic pausing of the print job
• Preservation of the current print progress
• Reduced risk of failed models and filament waste
• Precise compatibility with the Snapmaker U1 3D printer
• Original Snapmaker replacement part

When should the sensor be replaced?

Replacement is recommended if the printer incorrectly reports the presence of filament, fails to detect the inserted material, or does not respond when it runs out. The sensor is located inside the print head's extrusion unit, and the kit also includes the required mounting screws.
