Is it possible to save the projects in *.stl* format?

I have to save the project in a format thet is OK for my nprogram to silicing so I can print it.
the format thet my programme supports are: .fpp.stl*.obj*.3mf*.slc*.g*.gx*.svgx*.x3g*.bmp*.png*.jpg*.jpeg

If you are using 2016 Make, you need to go to the extension warehouse and download the .stl extension. This will allow you to export .stl.
I think you’ll need to download it in a browser and install it manually as I think 2016 nolonger has direct access to the E Warehouse.
