Exporting an STL

Before they can be used in a 3D printer, 3D models created in Blender have to be changed to a file that the 3D printer can use. Blender's default file format isn't readable by 3D printers and can sometimes contain additional information that the 3D printers don't need.

Most 3D printers use a file format called STereoLithography (STL), which contains just the final shape of the object. To export a finished model to an STL for 3D printing, follow these steps:

  1. Select the model or models to be exported.
  2. From the Info panel, choose File | Export | Stl (.stl).
  3. Navigate to a chosen folder or directory.
  4. Give the file a name.
  5. Click on the Export STL button or press the Enter key:

Now, the STL file will be available to send to a 3D printer or ...
