Sunlu Filament Connector FC01

The SUNLU Filament Connector FC01 is a filament fusion splicer that joins leftover or broken filament ends into a continuous strand - so you can keep printing without waste. Splice remnants from different spools, create smooth color gradients, or switch colors mid-print in seconds.

Key Features

• Zero Waste - Fully utilize leftover spool ends. Splice tail pieces together and save on new filament.
• Multi-Color Printing - Fuse same-material filaments of different colors to create gradients and multi-color models without a multi-extruder setup.
• Fast Heating - Reaches 185°C in about 3 minutes. Temperature accuracy within ±3°C for consistent, reliable splices every time.
• Wide Material Compatibility — Supports PLA, ABS, PETG, PCL, PA and PC at up to 240°C. Works with 1.75mm diameter filament.
• Safe Design - Advanced insulation keeps the external surface at 50–100°C during fusion. Hot where it matters, safe where you touch it.
• Quick Fusion - Splice completes in just 10–15 seconds. Simple interface, no complex setup needed — perfect for beginners.
• Visual Monitoring - Built-in window and display screen show real-time temperature and process status at every step.
• Strong, Clean Joints - Professional fusing technology produces smooth, seamless joints that won't affect print quality or surface finish.
