UM3 and abrasive material

[eragonsmith 0]

Good afternoon,

I have an UM3 printer and I want to use abrassive material, usually carbon black filled filament. I would like to know if you have tested these material and if it is possible to change the nozzle to other more resistant. I know it is at my own risk but any piece of advice is really welcome.

Searching I found solex nozzle and they sell something called everlast nozzle. I know it's another company but I am trying to design some experiment and I need that kind of materials with non-zero conductivity.

Thank you very much in advance.

CF will wear out your nozzle pretty quickly and wreck it. Basically it sands the tip flat such that the nozzle gets shorter and shorter and quality gets much worse and eventually it fails.

I recommend you get the 3dsolex hardcore with 2 nozzles and then buy also the ruby nozzle (or to save money if you aren't printing a lot of CF you could buy 1 or 2 steel nozzles).
