Here is a link to a Google Doc with many filaments listed, although it has not been updated in some time.
Below is a list of brands/types i have personally used in my X1cc's, and if they fit the AMS and some comments. Afterward are a number of other filaments that users on Reddit have reported to work in the AMS.
Brand - Type - Fit AMS - comments
Overture - Matte, PETG, TPU - Yes (Not TPU) - slow down first layer and increase temp by 10 for PETG (cardboard spool) (MatterHackers and Sunlu PETG are better)
Eryone - Silk, Metallic, Matte, Glitter - Yes
eSun - Silk, Matte, PLA+ - Yes - increased the temp on the generic PLA profile by 5-10 for the matte and PLA+
BambuLab - Matte, Basic, silk, PC, ABS, Support W/G, Metallic, Glitter, Tough, Marble, PA-CF, PLA-CF, PETG-CF, PAHT-CF - Yes - Love the PC, PLA-CF, and support W
Amolen - Wood, Silk, Glow - Yes - Love their wood and silk, Wood prints fine with .4 nozzle.
MatterHackers - PETG - Yes - Their PETG prints so good, Thanks to whoever on here told me to try it!
PolyLite - PLA Pro - Yes - Cardboard Spool, Prints great using Polylite profile
TTYT3d - Silk - Yes
DO3d - Silk - Yes - I think this is rebranded TTYT3D
CC3d - Silk - Yes
Bblife - Silk - Yes
Hatchbox - Wood, Matte, Glitter - Yes - their wood does not print well (then again it may have needed drying), love their Glitter
SunLu - Silk, ASA, PETG, PLA - Yes - Loving their ASA & PETG (can be a bit brittle); I run their PLA using the BambuLab profile and it prints great (cheap if you can catch on sale)
FilamentOne - Gitter - No (too wide) - Love the glitter but sucks to have to respool it to fit the AMS
Flashforge - Silk - Yes - prints great with generic silk profile.
Filaments others have reported on.
Polymaker - PLA, PLA Pro, ASA, PETG, PC Max, Support - Yes - (cardboard spools) print rings, use tape/adapters
IIID Max - PLA, PETG, ASA - Yes

These are of course all for the standard 1kg spools.
My favorites I have used in order BambuLab (faster, simpler) the PC and PLA-CF are AMAZING, Sunlu (PLA,ASA,PETG,silk), Amolen (wood, specialty silk), Hatchbox (all good), eSun (all good), Eryone (all good), TTYT3d (silk), CC3d(silk), and MatterHackers (PETG).
