So I played with all kinds of settings in PrusaSlicer. Nothing changed anything.
The only things that did improve the outcome some was:
-
Forcing the letters to be printed first: then the letters are smooshed and bleed into the background instead of the other way round, which arguably looks better / more legible. Nothing to write home about though.
-
Dropping the first layer’s height to 0.1mm (the other layers are 0.2mm high): that improves the letters a bit.
-
Dropping the first layer’s height to 0.05mm: because the first layer is so thin, it becomes kind of translucent and the wider white letter beneath it sort of show through. The net result is that it drops a kind of gaussian blur onto the lettering, which actually improves them - especially at a distance.
Other than that, there’s just nothing for it. And half of the suggestions I got concern other slicers, and I couldn’t find them or equivalents in PrusaSlicer. Oh well…
I guess that’s as good as it’s gonna get.
Besides printing issues: If I were a user of these adapters I’d be fine with what you got - it’s readable, and I wouldn’t expect high definition on this.
Thanks!
Yes, they’re perfectly serviceable. I’d just like them to look more “professional” I guess, for my personal pride 🙂
