Bambu support filament

Flagship K Series Creality Flagship K2 Plus & CFS

Anyone use this? What sort of material do I “tell” the printer and CFS to expect for this spool? Does anyone have any good advice, or links to good guides? My theory is you take advantage of the lower adhesion to generate support that is closer and denser than you could get away with if using the same material for support. Is that correct?

OK a bit more detail as the above post was rushed.

The Bambu dedicated support filament is actually a PC/ABS blend. There’s no such blend in the list of polymers in Creality’s list, that’s problem number one.

I CAN create a PC profile for Bambu Support filament in the main Creality Software and tell it that the printing range is 190-220 like it says on the reel (on the web it says 190-240). BUT, if I tell the CFS unit to expect PC, it defaults to a temperature range of up to 300 degrees…I don’t know if it will actually USE that for flushing operations etc, at which point I’m likely to fry the support filament…so I’m forced to “lie” to the CFS and tell it to expect PLA.

Anyone got any better suggestions other than the guesswork I’m currently using?

Thanks

I would not use/buy this filament.
PPETG for PLA or PLA for PETG is at least as good!

Hello GreyArea,

As far as I am aware, the support is printed on each level as is the overall print is and therefore if the support is printed at a different temperature than the main filament, isn’t the temperature going to change many times it prints a level ?

I hope this makes sense. I can’t think of another way to describe it.

Is it not possible to find a water soluable support filament of the same type (PLA/PETG/ABS etc) as the structure is printed with ?

Cheers.

I don’t know of any water soluble PLA/PETG or ABS. The only water soluble I know is PVOH and the CFS has a big “do not use PVOH” sticker on the inside of the lid.

I suppose if I’d been able to set the machine to recognise the support filament as an individual entity, different temperatures from the actual building material would be an issue. As it was due to conflicts arising from being able to identify support material in two or three different places, whilst I could get the software to use a dedicated spool for support, I wasn’t able to set up any different parameters for that particular chemical type - so I just had to tell the software it was PLA…
