Hi
Very intersting thread! Recently I did a lot of printing with support involved. I use PLA-CF with PETG as interface layer, which works very well.
Well, the more you dig into the topic, the more flaws you will find.
I had some issues with Bambulab Studio, which I describe here:
This is pure software and should be solved soon by bambulab.
I never had trouble with clogging. However, I’m also concerend about the loss of structural strength. Often it will not be noticed, because the part is strong enough. But for sure there are some situations where you just need all the layer bonding strength possible.
Does anybody know the volumetric flow of the flusing? Maybe the flushing volume could be significantly reduced if flushing would be done at a much higher flow rate (higher than for printing with the same material)?
If even 999 mm3 will not be enough to get the regular layer bonding, this would be a real bummer!
