No difference at all - just different ways to write the same thing, sort of.

I prefer the simpler "3D" to imply Stereoscopic 3D, but will use also "3-D" when referring to products that use "3-D" in their title. Also note that in the age of CGI filmmaking, "3D" has come to mean anything rendered in three dimensional software (like Pixar movies).

Because of this double meaning, sometimes I'll write "Stereo-3D" to be clear. But typically if I write 3D, I mean it in the stereoscopic way.
