Hi! After printing several hundred kg of polyterra, i've noticed that it is far more abrasive than typical PLA. looking at your product page, it seems that it's filled with a "biocompound" - what is this compound?

hi! I believe this abrasiveness is known by users, but perhaps not stated officially

I tried to find that out, too, but they didn't want to tell 😅 They only told me it's something you can find in nature. Most matte filaments are slightly more abrasive than their smooth/glossy counterparts. What kind of nozzle are you using?

I used slice bridgemaster nozzles for a bit on a few of my production printers. After a few kg of material they were completely shot lol

#

Now I use hardened steel or tc exclusively, though

#

But I've recently been working on a filament sensor design using a rolling wheel, and the filament has been digging right through the wheel lol. Even used an aluminum bushing and the same thing happened.

#

I redesigned it to use a bearing and it seems better. But just wild how abrasive it is

Pics of the bridgemaster nozzle after about 6kg of polyterra ^

Well that nozzle is gone 😄 Seems to be a coated copper nozzle, so when the coating is gone, it's not surprising it chews through it like it's nothing.
I haven't noticed any problems with extreme abrasion with Polyterra, but I'm exclusively using hardened steel nozzles.

Pulled the only remaining production bridgemaster off a printer yesterday lol..

Running hardened steel on everything now

The abrasiveness of Polyterra is not mentioned in any official document. This IS an issue and it should be made clear.

Any filament is abrasive to some degree. The question is how abrasive it is and whether it's actually that bad or if this nozzle is just kinda weak. I mean it's copper - that's a very weak material. I don't think it would grind brass or steel down that quickly.

#

I think it's the nozzle who needs a warning to not use it for anything but standard colors 😅

Polyterra wore out two of my Revo nozzles very quickly unfortunately.

i personally havent noticed too much wear on my brass nozzle, but its only been like 2kg

Give it another few kg lol

#

It'll go

#

hmmm. i mean i've also been trying other filaments like different brands of PLA or also PC filament from polymaker etc

#

or abs from other brands

#

so i can't really pinpoint it to one filament. I used to use a hardened steel nozzle before I switched to revo, and Ive been waiting for obxidian nozzles to go back in stock for forever.

#

Sure, but abs, PC, etc are not abrasive like polyterra

#

They aren't filled

#

If 6kg wear out a brass nozzle, the product page should definitely mention it. @fading tusk
