"Support Filament for PLA/PETG" for PETG print .. adjustment?

Bambu Lab Software Bambu Studio

I’m a pretty noob here, trying to get into this “3D mess” as quickly and painlessly as possible, so please be kind if my question sounds stupid. OK, here it is:

I have a PETG print (body) and wanted to use PLA as a support (interface) … I get a warning in Bambu Studio, regarding using different filaments. OK, understand … there is an article at BWiki, with explanation and recommended parameters adjustment for both materials for such print. It sounds reasonable, I understand the reasons why such changes are necessary. Simply, I get it.

But now … instead of ordinary PLA, I’d like to use a special filament from Bambu “Support for PLA/PETG”. Again, just for the support interface (the main object and body of support will still be the PETG). Even now, Studio sends a warning (the same as before / different filaments). After reading some discussions, I understand that the warning is “a little bit generic” and doesn’t take a special filament into account. Weird, but OK, no problem …

But now the main point of my question … when using this Special filament for PLA/PETG support, do I still need to change parameters as was advised in BWiki (for ordinary PLA and PETG)? Or should I just ignore the warning and use the filament’s parameters as set in their default profile? This sounds logical to me, as a special filament should be OK as it is, without the need for user adjustment/input. But “logical” doesn’t mean “correct”, sometimes :slight_smile:

Appreciate your comments, in advance

That is a good question as this (strangely) isn’t mentioned in the wiki. It should be mentioned on the same page, at least.

@SupportAssistant can you clarify this? Searching for “Support filament” or “Support W” in the wiki yields over 1000 results (which is another problem you need to fix - only pages where both words are mentioned should hit that search).

Hi @Twitko

Welcome to the forum
Great start question; my view, backed up by official info, but not backed up by experience:

According to the datasheet of PLA/PETG, it is PLA, which may trigger the error.

Their wiki is quite extensive on the topic. What I would not ignore are the printing settings for the PLA/PETG support when supporting PETG:

Nevertheless, the settings respect the support for BL PETG HF. If you use a different brand, you may need to tune it up. I would try to match the support filament extrusion temperature to the PETG.
In any case, I would do a sample test before venturing into larger models.
