To speed up hollowing in 3D model supports, adjust slicer settings (lower density, simpler patterns) and split large supports—these steps cut print/slicing time without losing support strength.
- Reduce density to 10–25%: Less material speeds up printing, and tools like Cura/PrusaSlicer make this easy. - Use grid patterns: Swap honeycomb for grid—simpler structures slice faster, and many slicers have "fast support" presets. - Split bulky supports: Break large sections into smaller parts to avoid slow solid areas.
Beginners can start with preset profiles to test changes quickly.
