Thickening \u2192 Increased extrusion volume \u2192 Bulge<\/span>
Thinning \u2192 Decreased extrusion volume \u2192 Holes\/Discontinuities<\/span>
Essentially:<\/span>

Underlying reasons (not just ceiling height)\uff1a<\/strong><\/span><\/h4>

Thermal expansion and contraction + poor bed adhesion<\/strong><\/span><\/p>

Process:<\/strong><\/span><\/p>

The filament is extruded at high temperature (expanded state)<\/span><\/p>

It shrinks as it cools down<\/span><\/p>

The corners cool faster and begin to contract first<\/span><\/p>

This creates an upward pulling force<\/span><\/p>

If the adhesion to the build plate is weaker than the shrinkage force, warping will occur<\/span><\/p>

solution\uff1a<\/span><\/h4>

Increase the temperature of the heating bed<\/span>
Increase adhesion<\/span>
Brim (of the skirt)<\/span>
Reduce the fan speed<\/span>
Close the doors and windows (to prevent cold air from entering)<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t
