• OK, you’re gonna need some things:

    A heat gun, A wire brush, Bandaids, A stiff drink

    • I heated up the nozzle separately in some boiling water and scraped off almost all of it. Then I put it back into the hot end and heated it up to 200 C, took it back out and q-tipped off a lot of the rest. There’s still some but I’m running a print right now and it’s working fine.

    • A SWAT team ready to mobilize, street level maps covering all of Florida, a pot of coffee, 12 Jammy Dodgers and a fez.

      • Mr. President, that man walked in here with a big blue box, and three of his friends. And, that’s the man he walked past. One of them is worth listening to.

      • It’s the second random post in which I find you randomly throwing Doctor Who quotes. They’re so on point every time, love that :D

  • A wire brush. Handheld, not attached to an electric grinder or something like that.

    Cheap wire brushes should be available in most hardware stores. I know that ours carries them in the paint section.

    Remove the nozzle and hold it with pliers or something.

    Use a knife and carefully scrape off what you can while cold. Heat to printing temp and wipe off what you can. Cool down and clean with acetone if need be. Edit: do this only with metal pieces. Disassemble head if need be.

  • What type of filament is that?

    Maybe try a heatgun to soften it. I’m not sure, might damage the plastic casing.

      • PLA basically doesn’t dissolve in any (readily available consumer-grade) solvents. Your best bet is going to be to take the entire unit as far apart as you can until it is metal only components, heat it with a heatgun to make the PLA soft/melt, and brush it all off with a brass cleaning brush.

    I have heated it up just until plastic becomes malleable and used a damp cloth. I have also used a soft wire tooth brush to remove

  • I just bought a new heating element when that happened to me.

    I might go back with some acetone now after reading others’ comments.

  • Hrrmm. Does it still print? Personally I’d go with hope it kind of burns off over time with normal use. Others may disagree…

    • Metal piece with many pointy pieces and neodymium magnets in a microwave? The sparks will damage the item and the oven. And won’t melt the plastic
