Why is bed adhesion 3D model messy when export?

Bed adhesion in 3D models often looks messy when exported due to incorrect slicer settings for first-layer adhesion or support structures. Slicers (tools that convert models to printer-ready g-code) control how the first layer sticks—if settings like brim size, first-layer flow, or bed temperature are off, the exported file causes uneven, stringy, or lifted edges on the build plate. To fix this, check your slicer’s bed adhesion options (e.g., brim vs. raft) for your model’s base shape and run a first-layer calibration print to adjust flow or temperature.
