When resin 3D prints have messy infill, it’s usually due to incorrect exposure time, insufficient infill supports, or resin that’s too viscous to flow evenly. - **Exposure issues**: Too little exposure leaves infill undercured and weak; too much causes warping or brittleness, both leading to mess. - **Weak supports**: If infill connections lack small supports, they shift mid-print, disrupting structure. - **Thick resin**: Viscous resin can’t fill tiny infill gaps smoothly, creating uneven layers. Fixes: Match slicer infill exposure to your resin type, add small supports for infill, and test a simple pattern (like grid) to diagnose the issue quickly.
