6. Иштөө нускамалары
Follow these steps to effectively fuse 1.75mm 3D printer filaments:
- Жипчелерди даярдоо: Ensure both filament ends to be joined are of the same material. Cut both ends at an oblique angle (approximately 45 degrees) to maximize contact area.
- PTFE жеңин салыңыз: Slide one of the provided PTFE sleeves over one of the filament ends.
- Align Filaments: Insert the other filament end into the PTFE sleeve, ensuring the cut ends meet inside the sleeve. Rotate the filaments to find the appropriate angle that minimizes the gap at the joint.
- Place in Heating Slot: Once the device has reached the set temperature and beeped, open the heating cover. Carefully place the connected portion of the filament (with the PTFE sleeve) inside the heating slot.
- Apply Pressure During Heating: Close the heating cover. During the heating process (typically 7-10 seconds for PLA), hold both sides of the filament and gently push inwards for 1-2 seconds to ensure proper fusion. The device will beep again when the fusion time is complete.
- Алып салуу жана муздатуу: Once the fusion time is reached, slowly remove the fused filament from the heating slot. Turn off the power to prevent accidental burns. Allow the fused filament to cool for 5-10 seconds, optionally using a fan to speed up cooling.
- Trim Excess Sleeve: Once cooled, place the filament ends into the cutting slot on the device. Press the top cover down firmly. The blade under the cutting slot will cut the PTFE sleeve. Remove the filament and the cut sleeve.

- PTFE Sleeves: Replace PTFE sleeves as needed. The package includes 200 sleeves for extended use.
9. Кыйынчылыктарды
- Filament Not Fusing Properly:
- Ensure the filament ends are cut at a sharp oblique angle for maximum contact.
- Verify that the correct temperature for the filament type is selected.
- Apply gentle, consistent pressure during the fusion process.
- Ensure the filament is properly centered in the heating slot.
- Түзмөк жылытылбайт:
- Check if the USB cable is securely connected.
- Ensure the power adapter is 5V 2A and properly plugged into a working outlet.
- Аппаратты күйгүзүү үчүн кубат баскычын басыңыз.
- Filament Snapping After Fusion:
- Allow sufficient cooling time after fusion before handling or applying tension.
- Avoid excessive pressure during the fusion process, which can deform the filament.
