Congratulations! From a side of printing that’s heavier-duty and plays with engineering materials more, have some knowledge:

• PLA+ != PLA. PLA+ is a monster of a plastic blend that’ll do a lot of heavy-duty things provided you keep the heat light
• Carbon fiber is not what makes a plastic strong. Treat CF blends individually – Nylons are usually pretty good structurally, PLA-CF less so
• Moisture content has a huge impact on print quality. +1 for a good filament dehydrator
• Keep yourself safe. Do not sand or cut filled plastics (-CF, -GF, etc.) without PPE! Don’t be the example case for new-age asbestos lung

This is also good advice for ABS/ASA and filled plastics. Honestly, I’m way less concerned about PLA fumes than I am styrene or potential airborne microscopic carbon fibers.

Probably wanna post in !general@forum.guncadindex.com, friend. This is the general-purpose 3D printing community on lemmy.ml. It’s like posting to /r/3Dprinting instead of /r/fosscad.

Fwiw I still haven’t gotten a response back from the mods about whether gun stuff is allowed, but it’s probably best not to bug the normal folks here if we don’t have to.

I keep telling myself that one of these days, surely, I’ll eventually leave my comfy Fedora rpm-ostree setup, try out NixOS, and make the most of its super unique package management.

Surely.
