How to hollow a bed adhesion 3D model for beginners?

As a beginner, hollow a bed adhesion 3D model using user-friendly slicers like Cura or PrusaSlicer—they have built-in tools to skip complex CAD software. Open the model in your slicer: Lower infill density to 5-15% (or use the dedicated "hollow" feature) and add 2-3mm drainage holes—these prevent trapped resin/air, critical for both FDM and resin printing. For FDM, keep adhesion strong with a brim; for resin, put holes in non-visible areas. If unsure, start with the slicer’s preset hollow profiles—they balance material savings and print quality for beginners.
