Converting .blend to .stl is an essential process for those looking to create 3D-printable models using Blender. While the .blend file format is native to Blender and contains all the data of a 3D model, .stl files are commonly used for 3D printing. Fortunately, Blender provides an easy way to convert .blend files to .stl format. To do this, simply open your .blend file in Blender, navigate to the 'File' menu, select 'Export', and then choose 'STL (.stl)' as the file format. You can then adjust the export settings and click 'Export' to save your file as an .stl. Keep in mind that during the conversion process, it's important to check the scale and units of your model to ensure it translates accurately to the .stl format. With this simple tutorial, you can now confidently convert .blend files to .stl for 3D printing.
