When a Prusa 3D model peels from poor bed adhesion, common causes are incorrect bed temperature, an unlevel bed, or insufficient first-layer filament squish.
Too low temp (e.g., PLA needs ~60°C, PETG ~70°C) stops the first layer from bonding; an unlevel bed creates gaps between filament and bed; nozzle too high (low squish) means filament doesn’t stick tightly.
Fix it by cleaning the bed with isopropyl alcohol, using Prusa’s "Live Z Adjust" to correct leveling, or matching bed temp to your filament—these simple steps often resolve peeling.
