LERDGE 1.75mm Filament Connector  For PLA/ABS/PETG/TPU/PC/PP/Hips Filament

Unlocking the Secrets of Seamless 3D Printing: Exploring the Importance of Filament Connectors

Whether you're a seasoned enthusiast or just starting your journey into the world of 3D printing, you probably need a filament connector. From enhancing print quality and reducing print failures to enabling multi-color prints and simplifying filament changes, filament connectors play an important role. Seamless 3D printing not only enhances the aesthetic appeal of printed objects but also improves their structural integrity. Without reliable filament connectors, the printing process can be riddled with interruptions and inconsistencies, resulting in poor print quality and wasted time and resources.


This filament connector is an auxiliary tool specially developed for FDM filament with a diameter of 1.75mm. Users can mix and match filaments of different colors arbitrarily, and can also recycle the remaining filaments. 

It is suitable for most popular filaments and 3D printers on the market. whether you own Lerdge-iX, ender 3, prusa MK4, bamboo Lap P1P or other 3D printers, you can use this filament connector. Filament Compatibility is very great.


Applicable Diameter: 1.75mm

Applicable Filaments: PLA/ABS/PETG/TPU/PA/PC/PA-CF

Temperature: Maximum 210℃

Input: 100-240V

Power: 24V 2A

Features of this filament connector:

※Easy To Use

Simple operation, high connection success rate, good surface effect.

※Compatibility Strong

Compatible with PLA/ABS/PETG/TPU/PA/PC filaments with 1.75mm wire diameter on the market.

※Intelligent Protection

When the filament connector continues to heat for 5 minutes, it will automatically power off to avoid overheating accidents.

※Rapid Heating

The filament connector uses miniature PTC heaters, which has a fast heating speed. At the same time, it is equipped with an aluminum melting tank, which has good thermal conductivity and can achieve rapid heating.

※Strong Practicability

Users can use their imagination and use the filament connector to freely match the color of the filament, and at the same time, they can also connect multiple rolls of residual filament for 3D printing.

Packing List:

1,Filament Connector *1 PCS

2,Adapter*1 PCS

3,Clip*2 PCS

4,Non Stick Paper*1 PACK

5,Sanding Strip*1 PCS

6,User Manual*1

Steps for Using filament connector: 

Step 1: Use non-stick paper and clips to secure the filaments that needs to be connected. 

Step 2:  Align the filament connection position with the aluminum melting tank and put it in.

Step 3: Turn on the switch and wait for heating.

Step 4: After heating is complete, tae out the filament after cooling for 5 minutes, and then enjoy it!

Here are a few examples of successful applications where filament connectors have played a pivotal role:

1. Multi-Color Prints: Filament connectors have made multi-color printing accessible and hassle-free. By connecting different filament strands of varying colors, 3D printing enthusiasts can create stunning multi-color prints with ease. Whether it's a vibrant model, a detailed map, or a personalized figurine, the ability to seamlessly switch between colors adds a new dimension to 3D printing.

2. Large-Scale Prints: Printing large-scale objects often requires multiple filament spools. Filament connectors allow users to join the filament strands together, ensuring a continuous flow without interruptions.

3. Filament Recycling: Filament connectors are also instrumental in filament recycling efforts. By connecting leftover filament scraps or failed prints, users can create new filament spools for future use. This reduces waste, maximizes resources, and promotes sustainability in the 3D printing community.

4. Unique Color Blends: Color mixing connectors have opened up a world of possibilities for designers and artists. By combining different filament colors, they can achieve stunning gradient effects, create custom color blends, or experiment with unique patterns. This level of creative freedom has revolutionized the way artistic and decorative prints are made.

These examples demonstrate the versatility and impact of filament connectors in pushing the boundaries of 3D printing. With the right connectors and a dash of creativity, the possibilities are endless.

Tips for Using Filament Connectors Effectively

Here are some tips to help you use filament connectors effectively:

1. **Prepare the Filament Ends**: Before connecting the filament strands, ensure that the ends are clean, straight, and free from any debris or impurities. Trimming the ends with a sharp knife or filament cutter can help achieve a clean and precise connection.

2. **Apply Proper Pressure**: When inserting the filament into the connector, apply gentle pressure to ensure a secure fit. Avoid exerting excessive force, as it can lead to filament deformation or breakage. A snug connection without any gaps or wobbling is ideal.

3. **Check for Filament Alignment**: After connecting the filament strands, check if they are aligned properly. Misaligned filaments can cause uneven extrusion, resulting in print defects. Adjust the alignment if necessary before proceeding with the printing process.

By following these tips, you can maximize the performance of your filament connectors and enjoy a hassle-free printing experience.
