Question about Basf Filament

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.
