Hi, all! Please help me out. T_T.
most of my resin 3D printing models have creaks like the picture shown. does anyone know? please help me. I`m confusing. it was fine after printed out. however, after 15 days or more, it has cracksAttachment 14698Attachment 14697
Did you hollow the model and add escape holes? If liquid resin is still in there it can crack and the resin leaks out. Which is of course dangerous for anyone handling the model. I had printed a Benchy months ago and the holes closed during printing. I ignored it and just a couple days ago I found cracks and it was all wet. I quickly washed it off and left it in the sun for those cracks to seal up.
Hi, thank you for reply. Right. It happened to me before when I hollowed some models. They were all cracked and resin everywhere on the displayed area. No, I didn’t hollow this model. It still cracked even it isn’t hollow. Could it be possible that I didn’t cure long enough?Quote:

I actually just posted a video on supports and talked about hollowing in the beginning.
