1.1.2 Molding
생성된 master 위에 polyurethane, silicone 같은 elastomer를 부은 후 열, UV 등으로 굳혀 master로부터 떼어내어 최종적으로 일종의 stamp 기능을 하는 mold를 만드는 과정이다.

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

Some experts predict
this modern marvel
might one day impact
our daily lives.
This is
homecoming day for Apollo .
The last round trip to the moon
Americans may take
in this century.
Thats right! Now anyone
can turn their ordinary TV
into a magic box of video games.
I, Gerald R. Ford, do solemnly
swear that I will faithfully...
We must whip inflation

What is soft-lithography?
So, an alternative and non-photolithographic method that we call soft lithography was developed. Because this method uses a patterned elastomer(e.g. PDMS(Poly DiMethyl Siloxane)) as the stamp, mold, or mask to generate micro-patterns and microstructures, it was titled as 'soft' lithography. As compared with photo-lithography, soft lithography has many kinds of strength.
