When the 3D printed structures were printed utilizing FDM 3D printer the layer grooves were generated on the structures. The layer grooves make the 3D printed structures strength decrease. Therefore authors already devised the 3D-CMF (Chemical Melting Finishing). The 3D-CMF is the method that dissolve the convex part of the layer grooves and filled in the concave part of the layer grooves and smoothen the layer grooves.3D-CMF reduces the cause of breaking of the 3D printed structures, which is considered to increase the strength. In this paper, we investigated the fundamental characteristics of the 3D-CMF and demonstrate of the change of the strength of the 3D printed structures.
