Comment on Ender 3 V2 damage?
KingRandomGuy@lemmy.world 1 week agoIMO heat formed from stress will not be a big deal, especially considering that people frequently build machines out of PETG (Prusa’s i3 variants, custom CoreXYs like Vorons and E3NG). The bigger problem is creep, which suggests that you shouldn’t use PLA for this part.

Petg inside the enclosed though can definitely have a short service life, the original x axis idler on my mk3s gave up the ghost after a month or so of pretty consistent printing of abs in the summer, had expected it so i the first thing I did in abs was a set of prusa spares which lasted until I did a bear mod last year.
There’s obviously variation in filament though so YMMV, petg is still a solid material to use if you don’t have an enclosure (though I’m always recommending then if only for gasses and fine particles while printing)

Yeah, I agree. In the photo I didn’t see an enclosure so I said PETG is fine for this application. With an enclosure you’d really want to use ABS/ASA, though PETG could work in a pinch.
I also agree that an enclosure (combined with a filter) is a good idea. I think people tend to undersell the potential dangers from 3D printing, especially for people with animals in the home.

What filter would you use? I’ve never played with abs because I didn’t want to have to vent an enclosure outside, especially in the winter. But if it could all stay inside that’d be great.

Cute cat! Nevermore and Bentobox are two super popular ones.
Since you’re running an E3 V2, first make sure you’ve replaced the hotend with an all-metal design. The stock hotend has the PTFE tube routed all the way into the hotend, which is fine for low temp materials like PLA, but can result in off-gassing at higher temperatures such as those used by ASA and some variants of PETG. The PTFE particles are almost certainly not good to breathe in during the long term, and can even be deadly to certain animals such as birds at small quantities.
