SPM (Scanning Probe Microscope)
SPM is a branch of microscopy that forms images of surfaces using a physical probe
the interaction between end of the tip and surface of sample
not only the images of surface of sample but also the various physical properties of sample
The components of SPM

General Process of 3D printing
FDM - Fused Deposition Molding
FDM works on an "additive" principle by laying down material in layers.
The model is produced by extruding small beads of thermoplastic material to form layers as the material hardens immediately after extrusion from the nozzle.
The nozzle can be moved in both horizontal and vertical directions by a numerically controlled mechanism
3D printing
3D printing or additive manufacturing (AM) refers to any of the various processes for printing a three-dimensional object. Primarily additive processes are used, in which successive layers of material are laid down under computer control. These objects can be of almost any shape or geometry, and are produced from a 3D model or other electronic data source.

I. Introduction
Recently, what is the most urgent policy for Korea? There would be various answers, but it can be welfare policy. For example, both Park GeunHye and Moon Jae In, who got most votes in president of Korea election in 2010, made a commitment about economic democratization the policy for . It means that there is a lot of demand about welfare policy in Korea. Answer to these demands,
