Taz 5 - Stock extruder - Polymide PA6-GF

Filament
1

Hi,

I am interested in printing with Polymaker PolyMide PA6-GF (Glass filled Nylon) on a stock taz 5 extruder. I purchased a few Microswiss Plated nozzles, will these suffice? Will the GF Nylon damage any other components in the extruder or mainly target the nozzle?

Thanks,

Provided everything is lined up from the extruder, through the filament guide, through the metal mounting plate, and hot end, the wear will be primarily on the nozzle. If anything’s out of alignment, the filament will make its own path. Just ensure that if you’ve ever disassembled the hot end, that you reassembled it with filament threaded through to keep things aligned as you tighten things down.

If you plan on doing a lot, you might consider investing in a Diamondback nozzle, but since you already spent on the Microswiss, you should be fine with those for occasional printing in GF.

Thank you for the feedback and suggestions! Do you have any input on the topic of nozzle longevity with abrasive filament by increasing nozzle diameter? I suppose it depends on the length of the chopped fibers in the filament but I don’t know exactly how long those might be. I was planning on printing in a 0.8mm nozzle to allow the fibers to pass through more easily.

Fiber filament doesn’t bore out a nozzle. It’s way easier for the fibers to just push off into the hot liquid plastic than scratch away at metal, so increasing diameter beyond the size recommended by the filament isn’t necessary. Wear of a nozzle comes from the nozzle rubbing against the cooler filament with the fibers in it like it’s sandpaper.

The nozzle opening size increases from wear because the interior of a nozzle is tapered, so the more of the front you cut off, the more of the tapered interior you expose.
