This Blender add-on integrates PrusaSlicer directly within Blender, allowing for seamless 3D model slicing and export to G-code without leaving the Blender environment.
Slice models and open them in PrusaSlicer directly from Blender.
- Import configurations from a folder containing PrusaSlicer .ini configuration files. You can export those from a PrusaSlicer project using File > Export > Export Config, or you can find them online.
- Collection-based slicing: the settings are stored at a collection level: when selecting different objects to slice, the active configuration will reflect the current selection. This is especially useful when creating files for different printers.
- Slicing to disk (the .gcode will be generated in the same folder as your .blend file) or directly to USB devices.
- Customizing the slicing using overrides. The original configuration file itself will remain unchaged.
- Adding pauses, color changes, and custom gcodes at specific layers or heights.
- Multi Material Slicing: individual objects can be assigned to specific extruders:
- Objects can be used as modifiers, support blockers/enforcers, and as negative volumes.
-
Prusaslicer profiles for Prusa printers are bundled for convenience. You can find non-prusa profiles at https://github.com/prusa3d/PrusaSlicer-settings-non-prusa-fff .
-
You can bundle your configuration with the addon: simply export the configuration, and put it in the root folder with name bundled_conf.json.
- Clone or download this repository.
- Open Blender and go to Edit > Preferences > Add-ons > arrow on the top-right corner > Install from Disk.
- Click Install and select the .zip file of the add-on.
- Enable the add-on in the preferences.
- In the add-on preferences also specify the path to the PrusaSlicer executable. Commands (such as flatpak run) are also supported.
- Select the objects to slice in Blender.
- Find the slicing section in the Collection menu
- Select the configurations, and add any overrides or pause/color changes.
- Click "Slice" to generate and preview the G-code (it will be saved in the same folder as the .blend file) or "Open with PrusaSlicer" to export and open the model in the regular PrusaSlicer UI.
- Blender 4.2.0 or higher.
- PrusaSlicer installed and accessible from the command line.
- If after installing the dependencies the addon doesn't reload correctly, close and re-open blender, and re-activate the addon.
- If using a sandboxed PrusaSlicer such as the flatpak version, make sure PrusaSlicer can write temporary files (in Linux, this means being allowed to write to /tmp ). The AppImage version however is the only one i currently support.
- In-blender gcode preview
