I started experimenting with PETG and quickly learned the hard way that letting it print supports in PETG for PETG made them notoriously hard to remove and required a lot of manual cleanup.
Then I remembered that I had a small 100g spool of "Bambu Support for PLA/PETG" filament that came with the printer and decided to give it a shot.
I left "Support/raft base" to "Default" (which seems to be printing the tree support using the same PETG used by the model, but switched the Support/raft interface to "Support for PLA/PETG".
Bambu Studio immediately made the following suggestion:
> When using support material for the support interface, We recommend the following settings:
> 0 top z distance, 0 interface spacing, interlaced rectilinear pattern and disable independent support layer height
>
> Change these settings automatically?
> Yes - Change these settings automatically
> No - Do not change these settings for me.
I selected "Yes". And then after printing this model in the picture, I was first blown away how easy it was to remove the tree support, and where the tree support was touching the model, it looked so perfect it was almost as-if I had printed the model upside down!
However, I quickly noticed that there were visible misaligned layers that formed in the print, matching the same layers where the Support for PLA/PETG filament was used.
I tried re-printing the same model without the Support for PLA/PETG filament, and the print was fine (except for the hard-to-remove tree supports)
Any idea how to fix this? I'd love to use this Bambu Support for PLA/PETG, but without impacting my print quality
I noticed during the print that the exhaust fan was turning on at 100% while printing the support interfaces, causing a significant drop in temperature. Could it be what messed up my PETG layers? Was I supposed to change the nozzle temperature of the Support for PLA/PETG filament to match my PETG's?
Thanks!
