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?

    Yeah. PP doesn’t stick at all to PEI print beds. Issue is Prusa neither sells HDPE or PP. Neither do they sell printer cable of Printing these materials (build surface).

    For Polypropylene: e.g. Eryone is 26€ for 900g (should be more “length”/volume than 1kg of PLA). Fiberlogy is 50€/kg. Not that expensive without the Prusa tax.
