Ultimative "5x First Layer" PETG-PLA-PETG ....

🧾 Description:

With this simple test, you can assess the adhesion behavior between PETG and PLA.
The print shows how well or poorly both materials bond – especially after cooling.
Ideal for checking multi-material adhesion, temperature influence, or moisture problems in the filament.

Instructions:

1. Start with PETG as the first layer.
2. Print the next layer with PLA.
3. Then always alternate in the rhythm PETG → PLA → PETG → PLA.
4. After cooling, you can check how easily the layers separate from each other.

Print Parameters:

• Printer: Bambu Lab H2D (tested)
• Nozzle: 0.4 mm
• Layer Height: 0.2 mm
• Total Height (Z): 1.0 mm
• Scaling:
  • X/Y may be scaled (for adjustment to the print bed)
  • Z may not be scaled

Note:
Intended only as a test object for material adhesion – not a functional part.

Note:
If the layers are not smooth, you must dry the filament.
