Quick diagnosis
Improve weak infill by tuning temperature, flow, speed, infill pattern, and line width.
Likely causes
- Speed too high
- Temperature too low
- Flow too low
- Wrong infill pattern
Step-by-step fix
- Slow infill speed as a test.
- Raise temperature slightly if bonding is poor.
- Check flow calibration.
- Choose a stronger infill pattern for functional parts.
What to check before changing more settings
Only change one variable at a time. Save your current slicer profile before testing, use a small repeatable test print, and compare the result before moving to the next adjustment.
