Corner Warping
Medium to Fix
Corners of the print lift up from the bed during printing, causing warping and potential print failure.
What Does It Look Like?
Corners curling upward
First layer peeling from bed
Nozzle catching on lifted edges
Common Causes
Bed temperature too low
Poor bed adhesion
Cooling fan too strong
Thermal contraction of material
Solutions (Try in Order)
Start with Priority 1 solutions. Make one change at a time and test between changes.
1
Increase Bed Temperature
Warmer bed keeps material adhered
PLA: 60-70°C, ABS: 100-110°C, PETG: 70-85°C
1
Add Brim or Raft
Increases bed contact area
Brim: 5-10mm width, Raft: 3-5mm margin
2
Disable Cooling for First Layers
No fan for first 5-10 layers
Fan: 0% for layers 1-5, then ramp up
2
Use Adhesion Aids
Glue stick, hairspray, or specialty solutions
Thin even coat on build surface
3
Level Bed Carefully
Proper first layer is critical
Paper test or feeler gauge (0.1mm)
3
Use Enclosure (ABS/Nylon)
Prevents drafts and maintains temperature
Chamber temp: 40-50°C for ABS
Prevention Tips
- Save working settings for each filament type
- Perform regular printer maintenance
- Keep filament dry and stored properly
- Re-level bed before important prints
- Start with manufacturer-recommended settings
