Gradual transparent material in single object

Support Materials and Textures
1

I’m new to blender.
I have used different “grades/strenghts” of transparency in one object by assigning a different material to each set of faces. I would like the object to be transparent on the one side and gradually becoming more solid towards the other side. How can I get the visible lines between faces to “diffuse” from one to the other?
Thanks!

Do you need each section to have a different material ?

If not you can use a single material
