I found a small length of filament in the parts bin. I don’t know what it is, and nobody else here does, or remembers ordering it. I’m pretty sure it’s a sample that was sent by Prusa when we ordered the printer, and it’s probably not a special material.

It’s feels “gummy” and a lot softer than PLA, but not really rubbery either. And I tried printing something with it at 230C as if it was PLA and it’s clearly not hot enough: it’s able to flow out of the nozzle but it barely sticks to the bed.

Any idea what it could be?

    TPU if it is soft and like gummy/rubbery

    I use the stuff for seals some times, but more often it makes the perfect string for cat toys. Put a length on a stick, add some painter’s tape on the end, and wave it around; cats go nuts.
