Self-folding behavior of 153 μm-thick paper using the filter-paper method and its dependence on the printing density \(\:P\). (a) Relationship between filter paper loading time \(\:t\) and printing density \(\:P\). Under deformation suppression with weights, \(\:P\) increases monotonically with \(\:t\), indicating that stable control of \(\:P\) is achievable using \(\:t\) as the control variable. (b) Relationship between printing density \(\:P\) and folding angle \(\:\theta\:\). Because \(\:P\) and \(\:\theta\:\) show an approximately monotonic correlation within each series, \(\:\theta\:\) can be designed by selecting an appropriate value of \(\:P\).
