3d printer extenstion

I have installed the latest version right now.
I can not find the extension for 3d printer.
Can you let me know the extension and g code generator for 3d slicer.

This is the forum for 3D Slicer.

“3D Slicer is a free open source software (BSD-style license) that is a flexible, modular platform for image analysis and visualization.”

You may be looking for a different application called Slic3r.

“Slic3r is free software 3D slicing engine for 3D printers. It generates G-code from 3D CAD files.”
