What's so special about makerbot fillament?

[Bleddyn_Dunn]

Why do makerbot only recommend they’re own fillament in the 5th gen? Apparently using non makerbot fillament voids the warranty of the extruder? Surely other filaments can be used. I know normal reels don’t fit but surely you can spool other filaments on the makerbot reels? Or am I missing something?

Usually, cases like these aren’t because their own filament is special in any way, but is instead that they can’t guarantee the quality of any other filaments. They don’t want to replace a print head that you clogged by using a $5 reel from China, so it’s simpler for them to say that if you don’t use their filament they just won’t help you with any issues.
