Did you always 3d print with filament dryer？
If your 3D printed models always have small flaws, it could be because the 3D printer filament is absorbing moisture. Using a filament dryer to remove moisture from the filament can help improve the quality of your prints. The following picture shows a 3D print done with dried filament versus undried filament. You can see the print with the dried filament turned out much better with fewer defects. Removing moisture from the filament prevents flaws caused by popping and cracking as water evaporates from the hot plastic during printing.
Some plastics are worse than others in this regard. PLA can survive weeks in the open air, but some is so bad you can barely get it out of the box.
Mind you 3D printing (FDM anyway) is so fraught with potential problems, it's still not very mature compared to other tech, that it's a wonder any of us manage to do anything!
Take everything I say with a pinch of salt, I might be wrong!

Absolutely, moisture in filament can lead to printing issues. A filament dryer is a smart investment to enhance print quality. You might also consider adjusting the infill gyroid pattern in your slicer settings to optimize strength and material usage. It's remarkable how addressing moisture concerns can make a significant difference in the overall quality of your 3D prints. Happy printing
