Adding custom supports in PrusaSlicer can help improve print quality and minimize unnecessary support material, which is especially useful for intricate or complex models. Here’s a step-by-step guide for adding custom supports in PrusaSlicer:
1. Open Your Model in PrusaSlicer
- Launch PrusaSlicer and load your 3D model by dragging it into the workspace or by selecting “Add” in the top menu.
2. Switch to the “Expert” Mode (If Necessary)
- Custom support options are available only in the “Expert” or “Advanced” mode.
- Go to Configuration > Mode > Expert.
3. Enable Support Generation
- Go to the Print Settings tab.
- Under Supports, select “Generate Support Material”.
- Choose “Everywhere” or “For support enforcers only” depending on where you want support.
4. Add Support Enforcers or Blockers
- Click on Support in the top toolbar to find options like Paint-On Supports, Add Support Enforcer, or Add Support Blocker.
A. Using Support Enforcers
- Add Support Enforcer: Choose this to specify where supports should be placed.
- Apply Enforcer Shapes: Click on your model and select shapes (e.g., cube, cylinder, or paint tool for more precise areas) to apply support only to specific parts.
B. Using Support Blockers
- Add Support Blocker: Choose this if you want to remove supports from certain areas.
- Apply Blocker Shapes: Select shapes (cube, cylinder, etc.) and place them on areas you don’t want supported.
5. Adjust Support Settings for Custom Areas
- After placing support enforcers or blockers, customize support settings in the right panel under Print Settings > Supports for areas needing different densities, patterns, or angles.
6. Preview and Adjust as Needed
- Go to the Preview tab and review the generated supports. PrusaSlicer will display a layer-by-layer view that helps you confirm support placement.
- Make adjustments by moving or resizing enforcers/blockers as needed.
7. Save and Slice
- Once satisfied, slice the model, and save or send it directly to your 3D printer.
Custom supports in PrusaSlicer give you control over support placement, saving filament and reducing print time while ensuring critical areas have sufficient support
