¶ Fault Description
Models fail to adhere, show poor adhesion, or detach during printing at the center area of the Build Plate.
¶ Example 1
¶ Example 2
¶ Possible Causes
- High resin viscosity causing abnormal resin flow-back
- Insufficient Build Plate accuracy, or excessive gap between the Build Plate and LCD screen
- LCD screen loosened or improperly installed
- Poor release film condition, such as whitening, scratches, damage, or aging
¶ Troubleshooting Steps
¶ Check the Release Film
Inspect whether the release film has whitening, scratches, damage, or abnormal tension.
¶ Preheat the Resin
The optimal printing temperature for resin is 25°C.
If the ambient temperature in the printer location is below 25°C, it is recommended to preheat the resin before printing.
Place the resin bottle in warm water at approximately 60°C for about 10 minutes to help reduce resin viscosity.
¶ Enable Active Heating
If the printer supports an external heater or built-in tank heating function, enable it in advance to preheat the internal chamber or resin.
¶ Adjust Slicing Settings
Appropriately increase:
- Normal layer exposure time by 1–3 seconds
- Rest Time After Release by 2–3 seconds
For bottom-up LCD resin printers, you may also increase:
- Lift distance by 2–3 mm
¶ Check LCD Screen Installation Status
Check whether the screws securing the LCD screen are loose.
Verify whether there is any visible misalignment or gap between the LCD screen and the printer frame.
If abnormal, reinstall the LCD screen properly.
