  • I print in recycled PP-GF (glass fiber polypropylene) reclaimed from fishing nets at work sometimes, and the tape trick only half works for me. It sticks to the tape just fine but the tape doesn’t stick to the glass bed… Based on this video, maybe we just need better tape! The PP-specfic MagiGoo barely helps at all. Also, one would think the glass fiber would make it warp less but it absolutely hasn’t lol.

    Maybe on paper this stuff isn’t super toxic, but mine produces easily one of the worst chemical smells of any filament we’ve used, for some reason.

    Anyway, once you do get it to print successfully, it really is totally indestructible. Try to find post-consumer recycled stuff though, as hard as that is to do.



  • Oh, afaik even the typical SLA resin is “safe” in the sense that when it’s completely cured, it’s non-toxic (for now). But that doesn’t help with the eventual degradation and microplastics, unfortunately. Also, people are wayyyyyyyy more careless with the uncured stuff and the fumes than they ought to be…

    As far as the dental stuff is concerned, I have no idea if it’s actually different and in what way. My guess is, either it must be the same, or else it’s just so expensive that nobody sells it for the hobbyist market. If you find out different I’d love to know, a chance to sustainably resin print would be awesome!

    However, if you look into this, watch out for the massive amount of greenwashing in this industry. They’re doing stuff like selling the same old resin and calling it “eco friendly” or w/e just because they’ve like thrown some seaweed filler in it. Lying about the dangers, all sorts of stuff.
