Is Prusament PETG Matte Black abrasive?
Hi,
This might be a dumb question, but is Prusament PETG Matte Black is considered abrasive? Would printing that eat through my nozzle faster than "regular" Prusament PETG would?
Best Answer by Diem:
A very rough rule of thumb: The more pigments and additives, the more abrasion.
Clear and translucent filaments have least. Black and dark colours have very little. Pastel and white filaments have most, worst are very white titanium based filaments.
None of these are considered abrasive but they may make the difference between changing brass nozzles once a year and once every three months with continuous use.
Abrasive filaments begin with glow-in-the-dark which may wear out a brass nozzle in a week...
Then the metals according to their hardness - copperfill and brassfill are about as hard as a brass nozzle and really need steel or harder nozzles. But glass fibre and iron or steelfill require ceramic or ruby nozzles.
Carbon fibre and graphene seem to be variable but ruby nozzles are wisest.
Wood and cork fills are not considered abrasive but they are very likely to clog a narrow nozzle so 0.6mm is generally considered the smallest safe size - you may get away with 0.4mm for small jobs.
Cheerio,
