Most Abrasion Resistant Filament?
I'm helping my dad build a motorcycle, and he needs a part made which acts a shifter guide, helping to return the shift lever to a center position. This would be plastic rubbing against aluminum. I'm wondering, what would be an abrasion-resistant filament that is good for this application? Is abrasion even a concern here?
RE: Most Abrasion Resistant Filament?
PC Blend and carbon fiber filaments come to mind immediately.
Those hold up better under stress than the usual suspect PLA and PETg and such. PLA has been known to soften and deform under hot sun.
I would at least prototype in PETG. It's tough and works well in a lot of engineering situations.
When the part is working well you can consider a more exotic, probably nylon based, filament.
Abrasion shouldn't be a problem, PETG resists oils and greases well so lubrication is your friend.
Bear in mind that CF filaments may abrade other parts, including metals.
Cheerio,

It depends what exactly are you asking.
The most abresion resistant filament is probably peek, it costs around 800$ per kg, and you cant print with it on stock prusa.
I think second best would be from Igus. For your application it might be even better then peek. It is possible to print it on prusa but its one of the hardest filaments to print.
Next would be acetal (pom) and nylon. Pom is almost unprintable, releases toxic funes, not recommended.
So i think nylon is your best choice.
If the part is touching the engine it shoul hold up to at least 110c temp. For safety margin i would use something that is good up to 150c.
In this case i would look into htn nylon.
Carbon or glass filled materials will cause more abbresion.

Nylon is what I was thinking. Acetal was the first thought, but I don't have the equipment to machine it to the shape needed. Won't be directly on the engine, about 6" away from it which would be totally fine in open air. Thanks for the recommendations
