Meshy for Blender

Install the Meshy plugin in Blender so you can send models from the Meshy web app into your scene and prepare them for 3D printing.

Before you begin

  • Download the plugin, a .zip file, from the Meshy for Blender integration page. Don't unzip it. Blender installs the plugin from the .zip file.

  • You need Blender 4.2 or later.

  • You need a Meshy account. To send models with the bridge, you need a Pro plan or higher.

Meshy tested the plugin with Blender 4.2.6, 5.0.1, 5.1.0, and 5.2.0.

The plugin doesn't need an API key or a sign-in. You generate and texture models in the Meshy web app, and the plugin receives them in Blender.

Install the plugin

To install the plugin, follow these steps:

  1. In Blender, click Edit > Preferences.

  2. In the Preferences window, click Add-ons.

  3. At the top of the add-on list, click the drop-down arrow.

  4. Click Install from Disk.

    Blender Preferences window on Add-ons, with the drop-down menu open and Install from Disk highlighted

You can also install the plugin by dragging the .zip file into the Blender viewport.

Plugin panels

The Meshy tab has the Meshy Bridge panel and four panels that prepare a model for 3D printing. Its Help & Settings panel opens the plugin's user guide in English or Chinese.

Bridge to Blender

Meshy Bridge receives the models you send from the Meshy web app and imports them into the open scene, with their materials and vertex colors. To set it up, see Bridge to Blender.

Model analysis

Analyze measures volume and surface area. It also checks the mesh for problems that make a 3D print fail, such as holes, self-intersections, thin walls, and overhangs. To run the checks, see Model analysis.

Model cleanup

Clean Up repairs the mesh with Make Manifold, which fills holes, deletes loose and interior geometry, and makes the normals point outward. Its Delete Small Pieces tool removes scattered fragments. To repair a model, see Model cleanup.

Model editing

Edit hollows a model, rotates it so chosen faces sit flat with Align XY, and scales it to a target volume or length. To change a model, see Model editing.

Model export

Export saves the selected objects as STL, OBJ, or PLY files, with options for UVs, normals, vertex colors, and textures. To export a model, see Model export.

Prepare a model for 3D printing

To prepare a model for 3D printing, follow these steps:

  1. Send the model from Meshy to Blender with Meshy Bridge.

  2. In the Analyze panel, click Check All to find problems.

  3. In the Clean Up panel, fix the problems.

  4. In the Edit panel, set the model's size and orientation.

  5. In the Analyze panel, click Check All again to confirm the fixes.

  6. In the Export panel, export the model as an STL file.
