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?

You might have some polypropylene there. Really strong material! Won’t stick to shit, temperature resistant, chemical resistant, can bend without breaking… never tried it, personally but it’s interesting stuff.

And notwithtanding that the damn stuff is around $78 for a kilo of filament! My other guess was polyethylene (HDPE). These two are pretty similar mechanically, both being polyolefins, but polypropylene melts at a higher temperature.
