I’ve got a roll of Blue Geeetech ABS+ that starts to smoke when it’s still so cold that its layer adhesion is terrible, and just burns in the nozzle whenever it’s not actively extruding if the temperature is high enough that it sticks to itself. Obviously, this is bad, and it sooted up a nozzle so badly that it needed to be replaced before I gave up on it.

So far, the only ideas I’ve had are just to leave it on a shelf indefinitely or to landfill it, neither of which are a great use of nearly a kilo of plastic.

    Have you tested that is actually ABS? Is it burning because it’s mislabeled something else with a lower temp range?

    If it is really ABS, mix with acetone to make a slurry for bonding abs parts. You can also cast parts in molds from the slurry with limitations.

      When it’s hot, it stinks of hot ABS, and it dissolves in acetone. I’ve read that sometimes budget filament manufacturers will use the same pigment across their whole material range, even if it’s not capable of withstanding the print temperatures of some of them, but it’s ABS+ rather than pure ABS, so it could be full of mystery additives that don’t handle heat well, too.

      There’s not much point using it as glue as I’m not going to get through a whole kilo worth of ABS glue, and produce more than enough ABS scraps from test prints and support to always make a colour-matched glue anyway.

    Contact the company. First let them know you got a bad spool. Hopefully they will replace it (request a different product perhaps to prevent risk of being in same situation). Also could ask what they do with returned spools. Might just junk them but if anyone is able to recycle this somehow I would think it would be the manufacturer. Maybe they sell scraps to some other industry for example.

      It was £7, so likely not worth the effort - if they want me to pay to ship it back, then that would cost about as much as the roll did - and it’s now outside the warranty period, so that would be pointless anyway.

    I’d imagine one could make plenty of art from that many metres of blue plastic cord. No idea how to find a suitable artist, but someone sure would have artistic use for your waste!
