The SUNLU Filament Connector FC01 is a compact fusion splicer that joins 1.75 mm filament quickly and reliably, helping you use leftover filament, reduce waste, and save on material costs. It delivers strong, clean joints for consistent, high-quality prints.
Zero waste
Make full use of leftover 3D printing filament to minimize waste and reduce consumable costs. The fusion splicer significantly cuts filament end waste and lets you reclaim and reuse material for new prints — efficient projects with virtually no filament loss.
Creative multi-color printing
Easily fuse filaments of the same material in different colors to produce vivid, personalized prints. Ideal for multi-color models, color transitions, and creative DIY projects.
Fast, accurate heating
Reaches 185 °C in approximately 3 minutes to speed up workflow. Temperature accuracy of ±3 °C ensures reliable, even heating for consistent fusion performance.
Wide material compatibility
Supports up to 240 °C and works with common 1.75 mm filaments such as PLA, ABS, PETG, PCL, PA, and PC. Enjoy excellent bonding regardless of the material used.
Safe design
Advanced temperature control and high-quality insulation keep the external surface temperature between 50 and 100 °C during operation, providing safe and worry-free use.
Easy operation
User-friendly interface designed for beginners and hobbyists. The splicer requires an external power adapter (not included); use a minimum 5V 2A adapter to ensure reliable startup. Select the appropriate settings for your filament type and follow the included instructions and video tutorials. Typical fusion time is 10–15 seconds. For best results, dry filament before splicing to avoid moisture-related bonding issues.
Visual monitoring
Built-in window and display allow real-time monitoring of the splice process and temperature readout, keeping you informed throughout every step.
Efficient splicing, excellent results
Professional-grade fusion technology creates strong, smooth joints without compromising print quality. Produces seamless surfaces and reliable performance during printing, delivering high-quality results for both intricate and large parts.
