Guide for exporting into STL from popular 3D Modeling packages

 

1. AutoCAD - Exporting 3D solid objects:

Enter the “FACETRES” command and set it to a value of about 10, then enter "STLOUT", select the objects you want to export and type “y” when prompted if you want to “Create a binary STL file”.

 

2. Autodesk 3ds Max:

Go to “File -> Export” (Important: The STL export option is not available from the “Export > Export selected” submenu), select “*.stl” as type, enter your filename, click save then select the “Binary” option, finally hit “Ok”.

 

3. Autodesk Maya:

See others below.

 

4. Autodesk Revit:

Autodesk has a utility program (http://labs.autodesk.com/utilities/revit_stl/) that helps to export into STL.

Go to the above link and follow the instructions. Be sure to import back your exported file into a 3D software of your choice to check your model’s dimensions before uploading the file.

 

5. Blender:

Very straight-forward; Go to “File -> Export -> STL”.

 

6. Google SketchUp:

SketchUp needs an extension plugin (https://extensions.sketchup.com/en/content/sketchup-stl) to export into STL.

Go to the link above and follow the instructions on the webpage.

 

7. Rhino:

Go to “File -> Export Selected”, select the objects you want to export then choose “*.stl” as type, enter you filename and hit “Save”; “STL Mesh Export Options” will pop up:

Enter a “Tolerance” of “0.05 mm” if 3D printing in SLS (0.05mm is ½ our minimum SLS printing resolution) or “0.015 mm” for SLA 3D printing (0.015mm is ½ our lowest SLA printing resolution).

Click “Ok” then select “Binary” option, uncheck “Export Open Objects” and finally click “Ok”.

 

8. Others:

Some 3D editing programs still don’t support exporting to STL. In such cases it possible to export to one of 3D file formats supported by “Netfabb basic”, such as “.obj”, “.3ds”, etc.

“Netfabb basic” is a free software that can be downloaded from the Netfabb’s website (http://www.netfabb.com/downloadcenter.php?basic=1).
