Blender for 3D printing
Blender is an open-source 3D creation suite with tools for modeling and sculpting meshes. Before printing, check the model’s geometry, scale and wall thickness for the intended process.
The community 3D Print Toolbox extension offers mesh checks and export tools. Availability and installation depend on your Blender version.
Prepare a Blender model for printing
- Set scale. Check the intended dimensions and confirm how your slicer interprets the exported file.
- Inspect the mesh. The 3D Print Toolbox extension can check non-manifold geometry and offers a Make Manifold tool. Inspect the result and test the geometry after any repair.
- Export and slice. The extension provides quick export to STL and other formats. Open the exported model in your slicer and confirm the size, orientation, walls and supports.
