TL;DR
This study shows how to design 3D-printed items with special surface textures and fluorine treatments to control water interaction and reduce friction.
Contribution
A novel method combining 3D printing design and gas-phase fluorination to control surface wettability and friction is introduced.
Findings
3D design changes can create anisotropic wetting with water contact angles varying from 76 to 116 degrees.
Fluorination treatment duration alters the hydrophilic/hydrophobic balance of 3D-printed surfaces.
The combination of 3D design and fluorination reduces friction and improves wettability of complex 3D-printed items.
Abstract
In this study, a surface texture design technique for 3D-extruded prototype products was developed. The study determines some target functional properties of polymer-made items. Four series of experimental samples (acrylonitrile–butadiene–styrene (ABS), thermoplastic polyurethane (TPU), polylactide (PLA), and polyethylene terephthalate glycol (PETG)) were 3D-printed using the fused filament fabrication (FFF) approach. The morphology and hydrophilic/hydrophobic balance of the surfaces of the experimental samples were regulated directly by the 3D design and by gas-phase fluorination techniques. The observed distilled water and ethylene glycol edge wetting angles of the surfaces of the experimental samples were determined by a 3D filament stroke arrangement. It was shown that varying the 3D design promoted hydrophobization and provided anisotropic wetting (the distilled water edge angle of…
