So far I have tried, HIPS, Support for ABS, and ABS.
They all seem to be fusing to the PC, making it almost impossible to remove.
Sorry for speculating, but it may be (a little) helpful. There’s not much that PA will stick to. So it could be a candidate. The tricky part is likely going to be to get the support interface to stick to the support and prime tower.
As for ABS, I would have expected that to work. Maybe a small increase in top z-distance could make a sufficient difference while still giving acceptable quality?

Bambu Support for PA/'PET sucks, constant issues and it absorbs water like crazy. I now use PAHT-CF as I have it in stock and it works really really good. I just use it for the interface layers so it really doesn’t use much.
I was in the middle of a print and my PA/PET was breaking every 5 min. I threw in some PAHT-CF as its nylon based and was the same print temp as support for PA/PET. Print finished 5 hours later, no issues, easiest support removal. No issue laying on top of the PC-FR.
Yeah. I thought ABS would work. Sadly no PA on hand. Ill try increasing the z distance slightly, good thing its only a 35 minute print.
This was the ABS on PC (yes, the PC needs to be dried more). But after 5 minutes of picking at it with a screwdriver, then stabbing myself, this is all I could get.
Is PA an option? Sunlu EasyPA (lower print temp and less moisture absorbtion) is probably an even better option if you have a spool of that laying around. They shouldn’t bond and have very similar print temperatures.
Edit - I didn’t see that @EnoTheThracian already mentioned PA.
I would think any PA should work. I just couldn’t say due to modifiers some of the manufacturers add.
On that note. I have been using the PAHT-CF with Bambu PC-FR. I haven’t tried it with regular PC. In theory it should work. I’m most likey going to take the PA/PET off the roll and throw it in the trash and save the reusable spool.
Ill run one with PA6-CF just for the fun of it. I don’t have any of non-fiber filled nylon.
God forbid I get an excuse to go to Microcenter if that doesnt work well though.
I love microcenter. The closest microcenter from me should be about a 60min drive. However in southern CA its really like a 2 - 2.5 hour drive during open hours.
Thanks @EnoTheThracian and @Ulade.
PA6 worked surprisingly well. I wouldnt of thought of it.
Yeah. I am lucky enough to have one 22 miles away. Problem is Ohio is always doing road work, and if I leave at a bad time, it takes an hour and a half to get there.
