Run a quick diagnosis

Answer a few short questions to get a prioritized fix list.

Start diagnosis

Likely causes

Part cooling is insufficient
Increase cooling for PLA and slow down small layers so each layer has time to solidify.
Material is heat sensitive in the print environment
Keep PLA away from hot chambers and direct sun. Use PETG, ABS, or ASA for warmer applications.
Geometry needs support or orientation changes
Add support, change orientation, or split the model to reduce unsupported features.

Recommended settings by material

MaterialNozzleBedFan
PLA 195-210 C50-60 C80-100%
PETG 230-245 C70-80 C30-60%
TPU 220-235 C40-50 C30-50%
ABS 240-260 C95-110 C0-30%
ASA 240-260 C95-110 C0-30%

Prevention tips

Change one setting at a time and reprint a small test piece.

Keep filament dry and store open spools in sealed bags or dry boxes.

Clean the build plate regularly and verify the correct slicer profile before long prints.
