SOLVE PRINT PROBLEMS
Diagnostic guide for common 3D printing issues and their solutions.
COMMON PROBLEMS
DIAGNOSTIC REFERENCE
LAYER ADHESION
SYMPTOMS
Layers separating, weak parts, delamination
COMMON CAUSES
• Low bed temperature
• Incorrect nozzle temperature
• Poor bed leveling
• Contaminated bed surface
SOLUTIONS
✓ Increase bed temperature by 5-10°C
✓ Check nozzle temperature for material
✓ Re-level print bed
✓ Clean bed with isopropyl alcohol
WARPING
SYMPTOMS
Corners lifting, part detaching from bed
COMMON CAUSES
• Rapid cooling
• Poor bed adhesion
• Large flat surfaces
• Draft/airflow
SOLUTIONS
✓ Use heated bed
✓ Apply adhesion aids (glue, tape)
✓ Add brim or raft
✓ Enclose printer or reduce airflow
STRINGING
SYMPTOMS
Thin plastic strings between parts
COMMON CAUSES
• High temperature
• Slow travel speed
• Insufficient retraction
• Wet filament
SOLUTIONS
✓ Reduce nozzle temperature
✓ Increase travel speed
✓ Increase retraction distance/speed
✓ Dry filament before use
UNDER-EXTRUSION
SYMPTOMS
Thin layers, gaps in walls, weak infill
COMMON CAUSES
• Clogged nozzle
• Low temperature
• Filament grinding
• Incorrect flow rate
SOLUTIONS
✓ Clean or replace nozzle
✓ Increase temperature
✓ Check extruder tension
✓ Calibrate flow rate
PREVENTION TIPS
BEST PRACTICES
REGULAR MAINTENANCE
Clean nozzle, lubricate rails, check belt tension regularly.
QUALITY FILAMENT
Use fresh, dry filament from reputable manufacturers.
PROPER STORAGE
Store filament in sealed containers with desiccant.
CALIBRATION
Regular bed leveling and extruder calibration.
ENVIRONMENT
Stable temperature, minimal drafts, clean workspace.
SETTINGS
Use proven profiles, test before production runs.
