To fix layer peeling in 3D prints, address key causes—poor bed adhesion, incorrect temperatures, or weak layer bonding. Poor bed adhesion (dirty/unlevel bed) makes bottom layers lift—clean with isopropyl alcohol or add a raft. Incorrect nozzle/bed temperature (too low) stops layers from fusing—follow your filament’s recommended temps. Weak bonding from fast printing or low infill—slow speed slightly or increase infill. For warp-prone filaments (e.g., ABS), use a heated enclosure. For PLA, a textured PEI bed boosts adhesion and reduces peeling long-term.
