Max Flow Test for Bambu Lab H2D/H2S – 15-65 mm^3 – V2.1

15 to 65 mm3.

USAGE

• Open 3mf file
• Select PLA/PETG or ABS in “Project >” section of filaments menu.
• Adjust Temperature in the filament settings to a desired one.
• Print it. :)
• Observe height H in mm where defects start to appear.
• Your max flow will be: 15+H.

If you want to test any other filaments for which preset if not provided:

1. Choose desired filament profile
2. Select your nozzle type Standard or High Flow
3. Set Flow ratio to 1
4. Set Max volumetric speed to 200
5. Set Ramming volumetric speed to 10 (or what was the Max volumetric speed above originally)
6. Set Cooling > Slow down for better layer cooling to Off
    

INTERPRETING RESULTS

• For maximum print quality, look for where the seam starts having gaps.
• If you're making quick prototype, 90-95% of absolute max flow (where you starting to see abnormalities in the walls) will still provide good results.

CHANGELOG

• V2: Increased range to 65mm3. Added support for 0.4mm high flow nozzle. Added PETG and ABS presets.
• V2.1: Fixed flow rate for project filament presets (to 1); corrected line width to achieve 15-65 mm3 with flow=1.
