Top Layer Flow Rate Calibration Test

📏 Flow Ratios Tested

This model evaluates nine different top layer flow ratios to help you get the perfect top surface:

• 0.80
• 0.85
• 0.90
• 0.95
• 1.00
• 1.05
• 1.10
• 1.15
• 1.20

⚙️ Print Settings & Profile

• Layer Target: Top Layer.
• Ready-to-Print: The included .3mf file has all the specific modifier blocks pre-configured with the exact flow ratios. Just hit slice and print!

🛠️ How to Evaluate Your Print

• Print the model using the provided .3mf profile.
• Once finished, inspect the top surfaces of the printed squares.
• Check for Under-extrusion: If the lines leave distinct gaps, fail to connect to the perimeters, or feel rough and under-filled (typically on the lower ratios like 0.80 to 0.90), the flow is too low.
• Check for Over-extrusion: If the surface has raised ridges, feels rough, or looks messy because the nozzle is plowing through excess plastic (typically on the higher ratios), the flow is too high.
• The Winning Setting: Look for the square that is completely smooth and tightly filled without any visible lines, ridges, or gaps. Note the number on the top of that section and update your slicer's top surface flow ratio setting
