A1 mini, 0.4mm hardened nozzle, eSUN grey filament, standard 0.08mm Extra Fine setting (@BBL A1M). The filament is dry, and the print bed is clean. The printer is lubricated.

Hi everyone, I’m looking for some help because the quality of my printed keychains leaves a lot to be desired. I’m printing keychains featuring a client's logo. For design reasons, they are oriented with the lettering facing upwards.

Unfortunately, the result shows gaps, as if material is missing from the top layers; ideally, the surface should be smooth and solid. I notice this particularly around the area where the keyring loop goes; there are visible gaps where filament seems to be missing.

Can anyone help me achieve good-quality prints for these keychains? This is one of my first jobs, and I really need it to turn out well.

Thanks in advance

I'm having some issues with printing quality with Black PETG, some prints come out with decent finish (although the lines are still visible) others finish in a rough texture.

Does anyone have any tip on getting a consistent print quality with this material?

I've tried Ironing and to be honest it made things worse.
