Convert mesh to stl

What is the difference between .mesh and .stl?

Description: Mesh is a 3D graphic data file type that contains information about the surface of a 3D object. It is composed of vertices, edges, and faces that define the shape and structure of the object. Mesh files can be used to create 3D models for computer graphics and animation.; Stl is the standard 3D data transmission file format mainly used for 3D printing. STL contains surface geometry descriptions of 3D objects and it uses a series of triangles to describe the surface geometry of a 3D model.
