Creality Filament Detector Kit – Runout Sensor for Ender-3 V3 SE / V3 KE The Creality Filament Detector Kit is an official upgrade designed to provide automatic filament runout detection for compatible Creality 3D printers. It continuously monitors whether filament is present in the feeding path and allows the printer to respond when the filament supply is exhausted. This upgrade is particularly useful for long prints and unattended printing, helping prevent failed projects caused by unexpectedly running out of filament. Creality officially lists the kit as compatible with the Ender-3 V3 SE and Ender-3 V3 KE. Product Function During printing, filament passes through the detector before reaching the extrusion system. If the filament runs out, the sensor detects the absence of material so the printer can respond appropriately instead of continuing to print without filament. This helps provide: Automatic filament runout detection Reduced risk of failed prints Less wasted printing time Greater reliability during long print jobs More confidence when running prints unattended Key Features Official Creality filament detection upgrade Compatible with Ender-3 V3 SE and Ender-3 V3 KE Automatically monitors filament presence Helps prevent print failures caused by filament runout LED indicator provides convenient operating status Metal filament guide provides smooth filament feeding Simple structure for straightforward installation Frosted housing design complements the printer Ideal upgrade for long-duration prints Creality highlights the kit's simple installation, LED indication, precise filament monitoring, and metal filament guide as its primary features.
