Product Description

Make the most of every 1.75mm filament spool with the SUNLU Filament Connector. This one-button splicer helps join prepared ends of the same material so you can use leftover filament for more 3D printing projects. It reaches 185℃ in about 3 minutes at room temperature and offers adjustable heating up to 240℃. Preset settings support PLA, PETG, ABS, PA, and PC. For best results, join the same material type; different colors can be used, but PLA and PETG should not be fused together. The package includes PTFE sleeves for stable joining. A power adapter is not included; use a 5V 2A power adapter for proper operation.
