SUNLU FC01 is a practical filament splicer for 3D printing that lets you quickly and permanently join filament ends, minimize waste, and reduce costs. It offers fast heating, precise temperature control, and compatibility with PLA/ABS/PETG, making it suitable for both home and workshop use.
Make full use of leftover spools – instead of throwing away short ends, you can simply splice them into one continuous strand. SUNLU FC01 heats up to roughly the PLA temperature within a few minutes and performs the splice quickly, so you can continue printing smoothly and reduce work interruptions.
The device supports common 3D-printing materials (PLA, ABS, PETG) and 1.75 mm filament diameter. Thanks to stable temperature and good repeatability, the joint is strong and visually clean – ideal even for creative color mixing and creating gradient effects.
Main benefits:
- No unnecessary waste – splice leftover filaments into longer lengths
- Fast process – splice typically in 10–15 seconds
- Precise control – temperature accuracy ±3 °C
- Wide compatibility – PLA, ABS, PETG; 1.75 mm filament
- Easy USB power – 5 V / 2 A (adapter not included)
