  Control over the physical properties of materials is ubiquitously required in
many fields. One means by which this can be achieved is controlling the
internal structure of multi-component materials with an eye to enhancing
mechanical properties. Here, we focus on self-organized pattern formation in
phase separating materials, where microscopic patterns with a smooth,
continuous connection may be realized. We propose a feasible method to control
pattern formation using phase separation combined with continuous
``lamination'' of material, when material is continuously and homogeneously
layered on top of a base. We find that a random droplet pattern, a lamellar
pattern, and a cylindrical pattern are formed depending on the lamination rate
$V$. We clarify the dynamics of pattern formation, focusing on the mechanism.
This study may lead to the creation of new functional materials through
artificial pattern control.
