Filament Splicer for 1.75 mm Material

The SUNLU Filament Connector fuses leftover 1.75 mm spools so makers can use every gram of PLA, PETG, ABS, PA or Nylon. It joins lengths of the same material in different colours, letting hobbyists create multi-tone prints without buying new rolls. The device suits desktop 3D printing enthusiasts who want to cut waste and expand colour options on a single extruder.

Heats to 185 °C in Three Minutes

At room temperature the unit reaches 185 °C in roughly three minutes and can operate up to 240 °C for higher-temperature filaments. A built-in window and display let the operator watch the splice in real time while temperature control and insulation keep the process stable. The connector weighs 143 g and draws power through a USB port.

Requires 5 V 2 A Adapter and PTFE Sleeves

The package includes 200 PTFE sleeves but no power adapter, so a 5 V 2 A source must be supplied separately. One-button operation selects the filament-specific temperature, freeing the user from manual timing. The compact splicer sits on the bench beside the printer, turning scrap lengths into continuous feed without additional hardware.

Questions about this item

How do I install the SUNLU Filament Connector and what step is often missed?

Connect a 5V 2A power adapter, insert 1.75mm filament into the PTFE sleeve, select the material temperature, and press start; the step often missed is supplying the adapter because none is included.

What maintenance or replacement will the connector need later?

The 200 PTFE sleeves supplied are consumables; replace a sleeve whenever its inner surface shows wear or melt residue that could affect the next splice.

What limit appears first during sustained use of the connector?

The maximum operating temperature of 240°C caps the materials you can join; filaments requiring higher temperatures cannot be processed.
