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.

If problems persist, please reach out to 

When parts are not fully cleaned, liquid resin remains on the part after washing and cures into the part.

The blind hole with a drain hole at the base of the feature allows resin to wash out of the feature with solvent. With a swab, you can see that the blind hole retains liquid resin after washing while the drained hole comes out clean.
