Reply To: 3D printed minis dissolving

In a word – yes. It sounds like “resin traps”. Are they particularly large pieces? What can happen is if there’s a “pocket” inside a mini, you can end up with uncured resin, surrounded by a solid shell (imagine, let’s say, a character with a really big head, and the wall thickness had been set to, say, 1mm – although the entire outer of his head is solid, there might be a big empty void inside).

Anywhere where you get uncured resin trapped inside cured resin, eventually it leaks out. It can take months. My first experience of it was when I printed a large settee and forgot to add drain holes; I made the object hollow, thinking I’d save on resin – but then forgot to add drain holes to let the uncured resin out of the void I made! The end result?
Well, I still used up loads of resin (because it got trapped inside) and after about four month, the model turned “sweaty” then a bit sticky, then after a few weeks, it stuck itself to my shelf as the resin oozed out.

In short, it sounds like you had trapped uncured resin inside the objects.
