If you look in 
lilypond/usr/share/lilypond/current/scm/time-signature-settings.scm, you 
can see that the default for 3/4 time is for eighth notes to be beamed 
by the bar. To override this, add

\set beamExceptions = #'((end . (((1 . 8) . (2 2 2)))))

to beam eighth notes on the beat. Use \unset beamExceptions if you want 
automatic beaming to revert to the default:

\version "2.13.39"

\relative d'' {
    \clef "treble"
    \key d \major
    \time 3/4
    \repeat unfold 12 { d8 }
    \set beamExceptions = #'((end . (((1 . 8) . (2 2 2)))))
    \repeat unfold 12 { d8 }
    \unset beamExceptions
    \repeat unfold 12 { d8 }
}
