Abstract

Microneedle is an innovation in injecting drugs without pain and without leaving damage to skin tissue. Microneedles can be applied to drug injection, biosensing, and biological specimen extraction. In this study, we investigated the effects of material choice, aspect ratio, and layer height on the fabrication parameters of microneedles—specifically focusing on needle height, angle, and base dimensions. Utilizing an ANOVA framework, we analyzed how these factors influence the structural integrity and functionality of microneedles. Our findings reveal that material is the most significant factor affecting both needle height, base dimensions, and needle angle. The aspect ratio was found to primarily affect the needle height and needle base. In general, the best parameters are the aspect ratio of 1.3:1, precision model material, and 0.05 mm layer thickness.
