Cure-Through
Cure-Through
Additional cured resin on the backside of the slice in the Z-axis.
How to Identify
Cure-through can be diagnosed as follows:
- Holes or small features resolved too small and oblong in shape
- Text is distorted
- Engraved text appears to have reduced height
- Embossed text appears to have an upwards shadow

Troubleshooting
It is recommended that you review all the possible solutions before taking action to ensure you are pursuing the best course of action.
If the best course of action is not apparent, try the troubleshooting options in the order listed. Refer here for more tips.
Process, Material, and Hardware Checks
If any of these conditions apply to your print, take the corrective action and reprint to see if the problem is resolved.
Print Preparation or Part Design Adjustments
The following solutions will address print or part-related causes of the defects. Choose among the suggested actions below and select the best approach for your application. Usually only one type of adjustment is needed.

Explanation & Causes
Cure-Through - Z axis
Cure-through occurs when light penetrates vertically through a thin area of material and cures resin on the backside of the slice. It is essentially overcure in the Z-axis. This phenomenon causes holes to be oblong and 0.050 - 0.200mm smaller than nominal in the Z-axis.
Clear or light colored resins experience more cure-through as light penetrates through these materials more easily.
The printer software applies a cure-through correction to your slices, but some amount of cure-through may still occur.
Causes
Print Preparation or Part Design
How the part is oriented, supported, or designed is causing the defect.
Root Issue | Problem | Why Defect Presents |
|---|---|---|
Oriented | Holes in the Z axis are oblong | Additional resin cures along the window-facing side of the hole. |
Designed | Holes in the Z axis are too small | Too much light is shining through slices that define the hole. |
Resin
The printing material is expired, beyond the printing range in its pot-life, or has been improperly mixed, causing abnormalities in the print.
Root Issue | Problem | Why Defect Presents |
|---|---|---|
Resin color | Features are too small | Clear or light colored resins experience more cure-through as light penetrates through these materials more easily. |
