The Study of the Effect of Multilayer MXene Incorporation on the Properties of Polyacrylate Composites Fabricated by Stereolithography

Abstract

This study explores the incorporation of multilayer Ti3C2Tx MXene into a polyacrylate-based photocurable resin for stereolithography (SLA). Composites with 3–10 wt% MXene were fabricated and characterized for microstructure, electrical, mechanical, and dimensional accuracy. SEM and XRD confirmed successful MXene formation with partial agglomeration. Electrical conductivity improved up to 8 wt% loading but declined at 10 wt% due to filler aggregation. Mechanical testing showed reduced strength and stiffness but increased ductility with higher MXene content. Optical microscopy revealed high printing resolution, with ~3% error at the top surfaces and ~13% at the bottom. These results demonstrate the feasibility of SLA-printed MXene composites while highlighting the need for optimized dispersion to balance performance.
