Hello, I’ve noticed a significant layer adhesion problem when using a different material for the support interface. The part becomes very fragile at the layers where the printer uses a different material. This issue occurs across the entire layer of the part and also affects other parts printed at the same time. I’m using PLA for the part and PETG for the interface. How can I solve this problem? I suspect there might be a bug in the slicer software. Thank you in advance.
I am using different filaments for the interface layer. I used PLA as interface on PETG and PETG as interface on ABS, without any problems. It takes a bit longer than with one material only, but the result is way better. And with the AMS it is very comfortable.
Did you activate the cleaning tower?
Did you change the cleaning volume?
Significantly increase the flushing between the support and the main material. You are likely getting PETG mixed in with the PLA. The same issue happens with the Bambu PLA Support
I think you are right. I don’t use a cleaning tower, and I haven’t increased the rinsing. Should I do both, or is just one enough? If rinsing is sufficient, by how much should it be increased? Thank you in advance.
Yes, actually, that’s the goal. I use PETG to get supports that don’t stick to PLA. Other responses indicate that I should ensure the flushing is sufficient between filament changes.
How do you deal with the differences in temp ?
ive noticed many prove you cant, but yet not one prove you can , you appear to fall into the cant catergory
ABS and PETG was no problem, ABS and PLA is a too big difference, you get a warning from Bambu studii/slicer.
A problem that occured was a too low bed temperature. With ABS i use 90°C bed temp. By having a support in the lowest layers, the slicer set the bed temperature to 70°C. Lead to bad adhession, one corner liftet up from the bed while printing the higher layers.
I suggest Deeple or ChatGpt.
