Light-off delay refers to the time the building plate lifts up, waits then retracts while printing 3D models. If the light-off delay time is too high, it will take longer to complete the process. If the number is set too low, there is a higher chance of your prints failing.
What is Light-off Delay?
When an LCD 3D printer’s building platform retracts, it is important to allow enough time for resin to stabilize before the UV lights turn on — the time required for this is called light-off delay.
This is extremely important if you want to print out sharper 3D models with high resolution.
How Do I Set Light-off Delay on the Phrozen OS?
The light-off delay values on the Phrozen Interface are different from the settings on CHITUBOX. In Phrozen OS, you only need to dial in the value provided on our official . If your resin isn’t listed on our resin sheet, set delay time at 2000~5000 ms depending on the resin thickness. The thicker it is, the longer the delay time.
How is Light-off Delay Calculated on CHITUBOX?
The light-off delay on CHITUBOX is different from the Phrozen OS. The parameters consist of the total time of the Z-Axis moving up and down and additional stabilizing time before the UV lights turn on.
To calculate the light-off delay, we need to know the lifting distance, lifting speed, and retract speed. After learning how long it takes for the z-axis to move up and down. Add another 2~3 seconds to the total time. The value would be your ideal light-off delay. In short, this is what light-off delay in CHITUBOX means:
"Light-off Delay = Building Plate Up and Down Time + Additional Delay Time"
Here's an example for you using the parameters above, IF:
- Lifting Distance: 6mm
- Lifting Speed: 60mm/min (1mm/s)
- Retract Speed: 150mm/min (2.5mm/s)
- Lift Time = Approximately 6s
- Retract Time = Approximately 2.4s
- Building Plate Moving Time = Approximately 8.4s
The suggested minimal light-off delay time will be: 8.4+2 = 10.4s
The suggested maximum light-off delay time will be: 8.4+3 = 11.4s

1.The official is a good starting point, but it may require some adjustments before printing perfectly.
2. Light-off delay time is essential in resin 3D printing. With the correct settings, each layer will be printed in a much more stable manner, resulting in a better quality 3D print. But it is also one of the most neglected parameters. Please share your knowledge with the .
