Recently, hydrophobic and superhydrophobic natural surfaces have attained great attention due to their diverse properties. It was found that micro-geometrical features on these natural surfaces have a great influence on generating hydrophobicity. Butterfly and Cicada wings are commonly studied natural hydrophobic surfaces for bio-mimicking and their microstructures are simplified into micro-grooves and micro-pillars, respectively. In the present study, a nanosecond fiber laser is used to produce these micro-geometries on stainless steel AISI 304 surface and its effect on surface wettability is investigated. Experimental results show that fabricated micro-geometries have a wetting transition from hydrophilic to the hydrophobic state over time. In this study, a good hydrophobic surface with a large apparent contact angle of 120° is obtained with 150, 200 µm step size micro-groove geometry on day-29 and micro-pillar geometry with 200 µm step size attained the highest contact angle of 118° on day-4. The contact angle of the non-textured parent material surface is 75°.
