Fabrication of Deterministic and Random Surfaces Using 3-D Printing Technology for Psychophysical Studies of Roughness Perception

Abstract

For psychophysical studies of roughness perception, it is vital of importance to efficiently fabricate the sample surfaces that have different levels of physical roughness. In this context, the present study seeks to develop an efficient way of fabricating such sample surfaces using 3-D printing technology, which consists surface modeling, 3-D printing and measurement. Reliability of this method is ensured by conducting a psychophysical experiment with the samples fabricated using the developed method and comparing the results with those of the previous studies.
