Abstract Scope |
The use of 3D printing scaffolds has become popular because of its optimal customization and process time. Polylactic Acid (PLA) is a commonly used biocompatible and biodegradable filament material in 3D printing. However, PLA is naturally hydrophobic. Cell growth and cell adhesion on biocompatible polymers are affected by the surface energy properties and the interface. This study is focused on mitigating these problems by incorporating plasma micro-discharge surface modification to tailor the surface roughness characteristics of PLA towards the development of biocompatible substrates for enhanced cell adhesion and growth. There is limited research exploring how changes in plasma parameters affect the wettability and surface energy characteristics of materials. Consequently, this work will also review the changes of 3D printed PLA in wettability, surface roughness, and surface morphology as the input voltage of the plasma micro-discharge treatment (atmospheric pressure-based corona discharge) is varied. |
