I have an issue that’s been bothering me. When I print a wall with a recess on one side for a latch, the opposite side, which should be perfectly smooth and flat, shows an imprint or reflection of that recess. I’m not exactly sure what’s causing this. From the front, as shown in the photo, all the layers look fine, but when viewed from above under the right lighting, you can see that the layers don’t align as evenly as they should.
I’ve tried printing this with different filaments and settings, but it didn’t make any difference. I’m attaching some photos and the print file below. If anyone could try printing it themselves to see if they encounter the same issue, I’d really appreciate it. Has anyone experienced something similar and knows how to fix it?
Thanks for uploading the 3MF, it really helps take the guesswork out of answering questions like this.
Your expecting too much of the technology.
The cause you’re seeing is the interior filament shrinking at a rate different from the surrounding walls because there is a difference in material thickness.
Your model is only 4 walls thick and 3 layers where this feature appears. You appear to expect the single outer layer to not be influenced by the one behind it. That simply won’t work.
The only thing you can try in order to diminish it–but not get it to disappear altogether–is to change the wall sequence from the default of inner/outer to outer/inner. This will give the outer wall a chance to firm up first.
