Abstract

Recently, Additive Manufacturing (AM) technology was undergoing rapid development, incorporating nanotechnology to enhance the final product’s quality. Stereolithography (SLA) constitutes a form of AM that fabricates three-dimensional objects by solidifying liquid resin through ultraviolet light exposure, a process known as photopolymerization, layer by layer. Although SLA boasts exceptional print accuracy, its mechanical properties are comparatively weaker than those of other AM technologies. Graphene, a nanomaterial renowned for its exceptional thermal, mechanical, and electrical attributes, presents a promising filler for enhancing material properties. This study focuses on investigating the influence of integrating graphene oxide dispersion filler, at a concentration of 10mg/ml, on the mechanical characteristics of SLA 3D printed products. The research delves into the effects of varying filler additions, specifically at 1, 2, and 5 wt%. To evaluate mechanical property changes, tensile, density, and Shore D hardness tests were executed. The findings revealed that incorporating graphene oxide dispersion enhances the material’s tensile strength and hardness values, while causing insignificant changes in density. The optimal addition level was determined to be 2% weight, resulting in a 29% improvement in tensile properties, yielding a tensile strength value of 17.08 MPa, alongside a 7.6% enhancement in hardness value, culminating in a Shore D reading of 70.67.
