Printing Aluminum abrasive filament, replace hotend parts?
For an experimental project I would like to print a material which is abrasive to aluminium when it is molten. For this reason, I would like to know which part of the hotend might come in to contact with the molten filament, so I know which parts I have to replace by other metals.

I would just think nozzle.
I have a Prusa,therefore I research.

Lower end of heatbreak ( normally Stainless steel), and Nozzle, take your pick, Brass, Copper, Stainless, Hardened steel, Ruby...

Hi Chris
have a look at the cross section below
inside the red box at the bottom, you can see the heatbreak and the nozzle contact the filament
