Tear holes in hollow parts

[ogedney]

I am having issues with ‘tear’ defects in walls with hollow parts:

I think these are related to peel forces, but I cannot figure out how to fix it.

I am using clear cast resin on Form 4, printing with 0.6mm wall thickness, with 15mm holes in the cup and 2mm holes in other low points. Cup mitigation is enabled, and I have turned squish intensity down to 10.

This issue is reduced by increasing the wall thickness, but this is worse for casting.

Please send any suggestions for how to fix this my way!

@ogedney I’m sorry to hear you’re experiencing delamination in your hollow parts. Even with “Cup mitigation” turned on, for a part this large, the best way to address this is to add drain holes to your model. Please feel free to open a support case, and we’ll be happy to dig deeper into the issue for you.
