Drop the Print instruction (and its associated square brackets),
change the first two commas to the string concatenation operator <>,
and wrap ToString around the first instance of r:
Do[Export["f" <> ToString[r] <> ".dat"], f[r]], {r, 0, 2}]
Note: If you have very many of these things, you may want to add 100
(or 1000, or even 10000) to that first instance of r. Otherwise you
might be in for an unpleasant surprise when your operating system
sorts your files into an unexpected order. Thus, I'd do:
Do[Export["f" <> ToString[100 + r] <> ".dat"], f[r]], {r, 0, 2}]
