Description
It's about a function that was implemented better in Bambu Studio than in Prusa Slicer 2.7.1
Printer: Prusa XL5
Scenario:
Print object made of PLA (extruder 1)
PLA support structure (extruder 1)
Support Interface layer (extruder 2) with PETG
Top contact Z distance: 0 (soluble)
Pattern: Rectilinear
Pattern space: 0mm
Topinterface layer: same as top
In the Prusa Slicer, a support structure made of PLA with a rectilinear pattern is printed in the same way up to the interface layer.
Then 3 Inteface PETG layers are printed.
Here, the first inteface layer is printed in PETG and has poor adhesion on PLA.
There is no option to change this.
see picture 1 , first interface layer in PETG (Prusa Slicer 2.7.1)
Bambu Studio:
In Bambu Studio, under the first interface layer in PETG, the last layer of the support structure is printed like an interface layer, but in the material of the support structure (PLA) and only then are the other real interface layers printed with PETG. This gives the first PETG interface layer more strength or adhesion and the other layers are printed more reliably. This is standard in Bambu Studio and cannot be changed.

Here, the last support layer is still printed in PLA and the following interface layer in PETG find a solid layer for better adhesion

Suggested solution for the Prusa Slicer:
Flexible selection and settings of support structures and interface layers in terms of the number of layers and which material or extruder is used for each layer.
The whole thing separately for the top and bottom of the support.
A global bed temperature setting even when using different temperatures of the support materials.
