¶ Failure Phenomenon
The model and supports are fractured or missing.
¶ Possible Causes
- Low printing environment temperature leads to increased resin viscosity and slow resin flow-back.
- Insufficient normal layer exposure time, Rest Time After Retract, or lifting distance.
- LCD screen light degradation or UV light attenuation.
¶ Troubleshooting Steps
¶ 1. Resin Preheating
The optimal printing temperature for resin is 25°C.
If the ambient temperature of the printer 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 reduce resin viscosity and improve flow characteristics.
¶ 2. Enable Active Heating
If the printer supports an external heating device or a built-in tank heating function, enable it in advance to preheat the internal chamber or resin tank.
¶ 3. Modify Slicing Settings
Adjust the following parameters in the slicing software:
- Increase normal layer exposure time by 1–3 seconds
- Increase Rest Time After Release (if applicable)
- Increase lifting distance by 2–3 mm (for lift-type machines)
¶ 4. Check LCD Screen Light Degradation
If the print failure occurs suddenly, without any changes to slicing parameters, resin type, or ambient temperature, the issue may be related to LCD screen light degradation.
Perform the following checks:
¶ • LCD Exposure Test
Use the touch screen to select the ELEGOO logo to activate LCD exposure and check whether the exposure pattern is complete.
¶ • White Paper Test
- Remove the resin tank
- Place a sheet of plain white paper above the LCD screen
- Run the “Tank Cleaning” function to perform a full-screen exposure test
- Observe from directly above to check UV light intensity and detect dim areas
- Pay special attention to the area corresponding to failed print regions
Normal LCD Exposure Result
If the exposure pattern is incomplete, or if certain areas of the LCD screen appear significantly dimmer, it indicates LCD light degradation. In this case, the LCD module requires replacement.
