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.

FAQs

FAQs

What is the difference between the 200 PCS and 400 PCS options?
The only difference is the number of PTFE sleeves included.

Can this connector create automated multicolor prints?
No. It is designed to manually join compatible filament ends, not for automated multicolor printing.

Is this a filament recycler?
No. It joins filament ends; it does not recycle filament into new material.

Can it repair broken filament?
Yes, it can join compatible pieces of the same filament material.
