Explanation & Causes
Explanation
The part is not receiving enough UV exposure and is under-curing
Causes
Print Preparation or Part Design
How the part is oriented, supported, or designed is causing the defect.
Root Issue | Problem | Why Defect Presents |
|---|---|---|
Orientation | Long print time | Two-part resins at the end of their pot life may be under-exposed due to the resin's change in properties. |
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 |
|---|---|---|
Expired | | The resin may not cure properly if expired. |
Print Plan Adjustments
Print Plan Adjustments adjust the print plan to optimize mid to high volume production and/or address part defects.
In doing so, adjustment may both prevent or cause defects. Below are adjustments that can cause this defect.
Printing Stage | Parameter Type | Type of Adjustment | Why Defect Presents |
|---|---|---|---|
5 Exposure | Exposure Timing | Decrease | Decreasing UV exposure can cause the part to under-cure. |
