Question about Filament - 281884

@Dong Wang has already formulated this nicely regarding the pass criteria:

- Diameter, standard for desktop FDM is 1.75mm
- Printer capability (heating bed, hotend temperature)
- Bowden/Direct Drive, with PLA no issue, with Flexfill a very big issue, besides e.g. Idler voltage
- Acceptance of third party filament, do you need proprietary filament like Ultimaker or do you have an "omnivore" that

can process everything thermoplastic in its working range like e.g. original Prusa i3 MK3S+?
- Weight of the spool, can you support the weight (extruder, filament holder), at 750g a small problem, but relevant for 2.5kg or 10kg spools.
- Coil dimensions if the coil is not externally suspended - if necessary, print a short holder yourself.

Checking the existing spool also helps, is there a chip somewhere or is it just a pile of plastic or cardboard?

Yes, whether a filament is compatible with a printer depends on whether the diameter is identical (in this case 1.75mm) and whether the printer can produce the temperatures required for the filament. For flexible filament, depending on the flexibility, you may need a direct drive extruder.

The FlashForge Finder requires 1.75mm filament and PLA only needs around 200 degrees and is not flexible. So

this is very, very likely to be compatible.
