I have a model that I am printing in PLA and it has some overhangs and I am using the Bambu PLA/PETG support material and it isn’t sticking properly to the base.
I would use it only for the interface, not full support — a more economical and faster approach.
Have you dried it? Just checking
I am using it for only the interface. The bottom layer you see is the PLA Tree support. Thanks
I dried it a few weeks ago and kept it in sealed containers, but it has been out for a few days while doing the prints. I will try that on the next print.
Thanks
Besides drying, try reorienting the model.
What temperatures are you using for the build plate and the nozzle?
Since I am printing PLA for the most part, the bed is 55 and the PLA nozzle is 220, the Support for PLA/PETG is set for 210
And what is strange, is I just moved both filaments to my X1C change the printer in Bambu Studio and re-sliced it and printed. The layer looks like it is supposed to. So it appears to be something with the H2D?
Did you see any changes in the print profile (temperature, speed, etc.) when you switched the printer?
No, I didn’t change anything.
I didn’t say you changed anything, but filament profiles are linked partially to the printer also. In other words changing the printer can also change filament profile settings.
IC, thanks.
The filament settings are the same on both profiles except for the Prestart Fan speed, the X1C is 0 and the H2D is 2.
To combat the blobbed edges, 1. try calibrating your filament (even if it is from bambu the flowrate can be messed up!) 2. In slicer, go to Quality and hook the “REVERSE ON EVEN” parameter, which will reduce/prevent the raised overflowing edges.
Most important of all…
You can also see the support material there is curving, which means temp is
not maintained. If you use PLA and PETG, they need to be at almost same temp. I print PLA on 240 and PETG on 260 when i combine them.
That said, I think bambu put oil in their filament, because I always have problem using their PLA with almost any support materials combined.
It could be your settings too, check out my youtube channel for more.
BTW: use PETG as support interface for PLA , and use PLA as support interface for PETG. No need to use fancy support materials. Those two combined are the best of the best!
Thanks, but if you look, when I printed the same file with the same settings on the X1C it worked fine, so it seems like an H2D issue or the slicing program for the H2D.
I used the Support Material because it came with the printer and I wanted to use that up. I plan on using the PLA/PETG interface when I run out of the Support Material as a good way to use small leftover rolls.
Considering the H2D has stronger fans, try dialing down the % on both the min max. Might pull down the aux too.
I am getting the same issue on my H2D with Bambu support for PLA/PETG and PLA-CF. I ran the same support material on my X1C and it was fine. I’ve since dried the support material (again), no difference.
I’d already had a clogged left nozzle with this support material, which I cleared, and it still had the issue of support material not sticking to the print.
I then tried a new nozzle, which seems to resolve the issue for at least part of the print, then the nozzle collided with a support. Getting frustrated.
The right nozzle prints like a dream.
do both nozzles have the same size? I assume you dual-nozzle
Do both nozzles have the same SETTINGS?
Might want to save the support material for when it is needed, unless you want to have to buy a spool of it.
Slow it down and lower the cooling for the support filament. Set the interface speed to 60 or even 40.
