Surface Tension Dynamics in 3D-Printed Components: Exploring Materials, Manufacturing Technologies and Wetting Behavior

This study investigates the complex correlation between surface tension and the existing 3D -printed components , along with their manufacturing technologies to provide potential directions for understanding surface properties in 3D printing. The research focuses on the wetting and surface tensions of different polymeric materials pairs , with different 3D printed materials, such as PLA, bronze powder filled PLA, ABS, gray epoxy resin and white epoxy resin, with diiodomethane and water. The study employs advanced measurement techniques for systematic investigations of surface tension properties. Because of this, Krüss DSA30 is the most common surface tension measurement apparatus, specialized in the detection of drop shapes. In this work, the effect of 3D printing technology on surface tension dynamics was explored, using digital light proc essing (DLP) and fused deposition modeling (FDM) to develop insights into how strength characteristics are governed by the processes used to fabricate materials. The resulting data showed varying levels of surface free energy across a range of materials, s uggesting that white and gray epoxy resins may offer superior frictional properties coupled with elevated adhesion. Concisely, this work offers enhancing the functionality and performance of 3D -printed components across diverse applications in different sectors by establishing the foundation for optimized surface tension.
