This paper proposes a holographic printer, which produces 3-D hard copies of computer processed objects. For the purpose of automatic making of 3-D hard copies of distortion free, a new method to synthesize holographic stereogram is proposed. It is is flat format and lippmann type holographic stereogram which can be printed by one optical step. The proposed hologram has not only horizontal parallax but vertical parallax, so that the reconstructed image is completely free from distortions.

In this paper the principle and the method of the new technique are described, and the system constitution and the problems with the holographic 3-D printer are also discussed.
