Are 3d ultrasounds more expensive than standard ultrasounds? is it more expensive to have a 3d ultrasound performed than a standard ultrasound?

Depends: Different places charge different amts for things. 3-d ultrasounds are generally more of a gimmick for parents to see their babies. They rarely provide significant diagnostic information over a quality 2-d scan.

3D: 3d ultrasounds should be covered by your insurance. If not some offices may charge extra for it. It is sometimes necessary to have 3d to better evaluate the lining of you uterus or location of a pregnancy or a finroid.
