I don't think so. The cost would be extremely prohibitive. It would be far cheaper to print it in plastic and then add some reflectie coating.

Most metal 3d printers simply don't have the surface finish to make this feasible, never mind cost (it'd be ridiculous).

I guess i should have added a ;-).

Although the laser sintering printer downstairs produces quite nice surface finishes. Not good enough for an optical mirror, but definitely good enough for mm-wave antennas.
