Does the Lulzbot Taulman PCTPE Filament require the Lulzbot Mini Flexystruder to print? I just wanted to know before (possibly) ruining my extruder.

Thanks,

I wouldn’t worry about it. PCTPE is supposed to be flexible but it’s rather stiff. It’ll go just fine in your regular extruder. Just make sure to tighten your idler a little more because PCTPE has nylon in it and thus it’s a bit more slippery.

No, it does not require the Flexystruder. While a little more flexible than Bridge or 910, PCTPE is still relatively stiff and feeds just fine in the standard extruder.
