Voxels Hollowing 3D

Revolutionary hollowing technology that uses voxelization to provide superior control over your 3D model's interior.

  • Automatic Detection

Detect Pockets: Automatically identifies resin traps and highlights them in the voxel view

Suction Cup Detector: Scans models to find areas that could cause vacuum-related print failures

Visual feedback shows problematic areas before you print

  • One-Click Automatic Fixes

Auto Fill Interior Resin Traps: Automatically fills interior pockets that would trap uncured resin

Auto Fill Interior Suction Cups: Fills areas below detected suction cups to prevent vacuum failures

Ensures all interior cavities are either properly connected or filled solid

  • Manual Control Tools

Voxels Edition: Fine-tune which areas should be hollowed (blue) and which should remain solid (red)

Rectangle selection tools for precise control

Particularly useful for reinforcing specific areas or filling detected resin traps

  • Add Infill System

Generate internal support structures within hollow cavities

Configurable spacing between support pillars (10mm default for medium-sized models)

Perfect for larger models needing additional structural support


Access: Prepare tab → Right panel → Voxels Hollowing 3D

Auto Support Export Enhancement

Complete Preset Portability

  • Auto Support presets now export and import with their custom support types

Previously, exported presets would revert to "Support Medium" if custom support types didn't exist

  • Custom support types are now automatically created during preset import
  • Ensures overhang support settings are preserved exactly as configured

How it works:

1. Create custom support types

2. Assign them to overhang settings in Auto Support presets

3. Export the preset

4. Import on another machine or after reset

5. Custom support types are automatically recreated with correct assignments
