B.slicer

The ultimate slicing addon for Blender

Slice · Dowels · Flatten · Export SVG

Whether you're a designer, engineer, or hobbyist, B.slicer makes it easy to create detailed slices for your parametric design. Slice any object, flatten the results, add registration dowels, and export as SVG — all from one streamlined workflow.

✂️

Slice

Choose axis, thickness & spacing — click once to slice with the new Bisect engine.
📐

Flatten

Lay slices flat — ready for laser cutting, CNC, or packed layouts.
📄

Export SVG

One-click SVG export — no camera setup needed. Organized layers included.
🎛️

Slicing Modes

Extremity, Middle→Slice, or Middle→Spacing — full control over slice placement.
🔍

Check Manifold

Analyze mesh health before slicing — highlights problems right in the viewport.
🔩

Add Dowels

Place registration dowels between slices with an interactive 2D/3D tool.

How It Works

1

Slice

Select your object, adjust spacing & thickness, choose axis & mode, then click Slice.

 →
2

Flatten & Dowel

Flatten your slices for fabrication. Add registration dowels for perfect alignment.

 →
3

Export SVG

Select output path, name your file, and export — no camera setup required.

Simply select the object you want to slice, adjust the spacing and thickness, choose the axis and type of slice, and click Slice. The new Bisect engine delivers faster, more reliable results on dense meshes — with optional legacy Boolean fallback under Advanced settings.

Use Flatten to lay slices flat for fabrication, or enable Packed Flatten for a compact, space-efficient layout. Then export everything as an SVG file with a single click — no camera or extra settings needed.

What's New in v1.4.0

Major Update — April 17, 2026

⚠️ Make sure to uninstall the current version before installing the new one and restart Blender.

NEW New Slicing Engine
  • Replaced legacy Boolean-modifier slicing with a high-performance Bisect engine.
  • Significantly faster and more reliable on dense meshes.
Note: Works best with manifold objects. Use Check Manifold to verify. Legacy Boolean available under Advanced → Use Legacy Boolean Slicer.
NEW Slicing Modes
  • Extremity — Start slicing from the edge of the object.
  • Middle → Slice — Slice symmetrically from center; the center is a slice.
  • Middle → Spacing — Slice symmetrically from center; the center is a gap.
NEW Check Manifold
  • Analyze mesh health before slicing with a single click.
  • Highlights problematic geometry directly in the viewport.
  • Per-island analysis — healthy islands aren't flagged as errors.
  • Visual report popup with details and dismiss button.
NEW Packed Flatten
  • A compact, space-efficient flatten layout for your slices.
  • Enable Packed Flatten (Tight) in the Step 3 panel for a tighter arrangement.
EXPERIMENTAL Add Dowels
  • Interactive tool for placing registration dowels between slices.
  • 2D grid view with per-slice health status (Safe / Weak / Unstable).
  • 3D preview with draggable handles and trim/extend via intersections.
  • Smart Span placement with Alt+LMB.
  • Auto-place toggle for automatic or manual placement.
  • Undo / Redo support within the tool.

Smart Collection Management

B.slicer organizes your objects automatically in Blender's outliner: "Original Objects" (hidden), "Sliced Objects", and "Flattened Objects" — keeping your scene clean even on complex projects.

⚠️ When you export your sliced object as an SVG file, be sure to give the file a unique name to avoid overwriting existing files.

Release History
v1.3.3 PATCH

April 4, 2025

⚠️ Make sure to uninstall the current version before installing the new one and restart Blender.

Improvements & Bug Fixes

  • Fixed an issue where slicing large-scale objects caused unexpected errors or crashes. The slicing operation is now more stable and performs correctly regardless of object size.
v1.3.2 PATCH

March 5, 2025

⚠️ Make sure to uninstall the current version before installing the new one and restart Blender.

Improvements & Bug Fixes

  1. Added a Redo Panel for the Slicing operation, allowing users to adjust the axis, slice thickness, and spacing after execution.
  2. Implemented a Redo Panel for the Flatten option to correct slice orientation when automatic detection fails. Users can now manually select the correct axis if needed.
v1.3.1 PATCH

February 24, 2025

⚠️ Make sure to uninstall the current addon before installing the new one and restart Blender.

Fixed SVG Export Bugs

  1. Correct Scaling: The exported SVG file now maintains the correct scale.
  2. Organized Layers: SVG files are now structured in groups based on Blender's object collections for better organization.
  3. Fixed Corrupt Exports: Previously, some SVG files were damaged upon export. This issue has been resolved, ensuring reliable file output.

Enhanced Slicer Operator

  1. Warning for High Slice Count: A dialog warning now appears when too many slices are detected.
  2. User Confirmation: Users must confirm before proceeding to prevent accidental high values that could crash Blender.
