In this study, a new process, named as nano replication printing(nRP) process, is developed for printing any figure in the range of several micrometers by using voxel matrix scanning scheme. In this newly developed process, a femto-second laser is scanned on a photosensitive monomer resin in order to induce polymerization of the liquid resin according to a voxel matrix which is transformed from bitmap format file. After the polymerization, a droplet of ethanol is dropt to remove the unnecessary remaining liquid resin and then the polymerized figures with nano-scaled precision are only remaining on the glass plate. By the nRP process, any figure file of bitmap format could be reproduced as nano-scaled precision replication in the range of several micrometers. Also, nano/micro-scaled patterns for an extremely wide range of applications would become a technologically feasible reality. Some of figures with nano-scaled precision were printed in scaled replication as examples to prove the usefulness of this study.
