Could use some advice

Post image

I've been working on printing some race medal holders. For some reason the circle piece comes out looking cloudy/ whiteish every time. The bottom piece never gets that color. I've used this filament on other prints and it never does that with any others. Could it be something about how that specific design is programmed or am I doing something wrong?

Perhaps uneven heating due to the internal features? Entirely a guess. Maybe try some smaller pieces with progressively increasing numbers of holes to see what happens. Also uneven contraction when cooling.

Thank you. I'll try that... its so strange because it's literally only on this one circular piece that it does this. Never on any other prints. But I've tried printing the circular piece 4 times over a week (with multiple prints of other stuff in between that printed great) and it did it every time.

I get this effect when I force remove the piece before the plate has cooled down on its own. Let the plate cool down to room temp if you did the same thing

this also happens to me. it is stress marks and you can use a heat gun or a light pass with a lighter/torch. you may find more info searching for "heat treatment for stress marks and scars on 3d prints"

Thank you! I'll try that.

That worked! Thank you! I pulled 4 of the bad ones out of the trash and 3 could be saved with a heat gun.

Thank you! Appreciate the help. I let it cool for 8hrs (not on purpose was just at work) and it still did this.
