So I answer Pétrus's question about this related topic: 3d printer and health

Here is my feedback in only 3 months and about 3kg and about 400h of various prints on the 3D Filament brands on my Tronxy: 3d-printers / tronxy-x5sa-500-pro-improvement-z-axis-how-to-paste-a-toothed-belt-t16537.html
Purchased exclusively on Amazon, so you will easily find these references if necessary:
- Amazon Basic PETG: very average, lots of hair, poor layer adhesion despite many different settings (but I haven't tested other PETG brands yet) 30% of the coil remains (blue)
- Sunlu PLA +: good but not so "more" than that for the more I expected more improvement (almost the same as PLA at the level of surface quality ... odors in PLUS ... well yes it is MORE fragrant what!) but the parts seem a little more resistant anyway
- Enotepad 3D PLA Carbon fibers: good but impossible to print durably in nozzle of 0.4 (hardened) and 0.5 (stainless steel), must print in 0.6 (stainless steel) otherwise it clogs (I am in bowden, not direct drive therefore, the extruder is deported ... I not know if that counts in nozzle clogging but certainly a little).
- Multicolored 3D PLA Enotepad: Ok, the spool is at 20% without much problem.
- Xingtong Zhi Lian Technology transparent PLA: Ok, the reel is finished, no big problem except that it was never transparent (whitish)
- Xingtong Zhi Lian Technology PLA Wood: there is real wood in it (20 - 30%?) you can feel it during printing. the filament is brittle and unusable on my machine
- CREOZONE TPU black: i only printed one small piece which looks ok but has quite a bit of hair. I printed at low speed (30 mm / s of memory, the tronxy allows 100 mm / s) and it is ok despite the remote extruder (a lot of people say that it is not possible to print TPU without direct drive)
To summarize, I would therefore advise against the brands: Xingtong Zhi Lian Technology and Amazon Basic. With a slight downside on Amazon Basic as long as I haven't tested other PETG filaments.
For the rest it's kif kif.
Coincidence, there is precisely a poll underway on this FB group:
After that you should know that:
a) One printer is not the other and a filament that can work well on one may cause problems on another model.
b) It seems, according to the comments, that there can have temporal variations of quality on the same brand ... (quality of manufacture variable in one direction or another)
c) Some filaments are hygroscopic, so they must be stored away from air. The best is to systematically protect them all.
