Abrasion‐resistant superhydrophobic architectures toward diverse mechanical damages. a) The superhydrophobic mechanism diagram of the printed superhydrophobic object being damaged locally. b) The optical images of the printed superhydrophobic objects being scratched by a knife and subsequent water droplet sliding off test. c) The superhydrophobic mechanism diagram of the full upper layer of the printed superhydrophobic object being damaged. d) The optical images of the printed superhydrophobic objects being filed and subsequent water droplet sliding off test. The printing parameters for these samples are 4 wt% HFS/PP weight ratio and a laser power density of 0.0725 J mm⁻².
