Approach to Exotic Materials
Have been working with Prusas for years now but have never risked working with exotics like carbon or wood/bronze filled on these machines.
Understand from previous experience with other machines that you must use some hardened steel nozzles when using these abrasives and was wondering what approaches people use?
Change nozzle? Change complete hotend? Keep a spare hotend that is configured just for abrasives and swap in and out?
Where do you get your hardened steel nozzles, Ali?, E3D?, etc .., any experiences with different vendors and what sizes do you use for what materials?
Any input is welcome.. thanks..

RE: Approach to Exotic Materials

Occasionally I print wood, and I'm just swapping my regular nickel-coated copper nozzles for hardened steel nozzles by E3D (bought at PrintedSolid). I guess nozzles with a wider bore (eg 0.6 mm) are recommended but I haven't had any issues with 0.4 mm nozzles.

I fitted a nozzle x not long after I got my printer.  As long as you make sure your filament profiles are modified to print 5-10 degrees hotter for everything then its not a problem.  Print what you want, when you want, just clean out the higher temp stuff as usual before going back to a lower temp material.

I did have one roll of wood filled material that clogged up every single time with the 0.4 nozzle though.  It prints 'ok' with a 0.6mm one though.  It wasn't particularly good quality filament in the first place.

My main issue with wood filled filament was crazy stringing. Any brand I've tried. Very hard to dial in. But on the other hand, it looks gorgeous when the heat gun has done its job!
