3MF format is designed for 3D printing so while you can certainly use TIFF graphics for making simple 3D models or geometry that you can export to 3MF format, it's not a matter of simple tiff to 3mf file conversion or resaving. So not impossible, but not really simple.
What you have to do is to first make 3D model in OBJ or STL format and export that to 3MF format. Many 3D modeling tools exist for this, for example the free Blender.
