The rapid advancement of additive manufacturing (AM) methodologies has garnered significant attention for its potential to enable sustainable, flexible, and mass-customizable production. Among these techniques, direct ink writing (DIW), an extrusion-based 3D printing method, stands out for its versatility in accommodating a wide range of ink materials. However, the limited availability of commercial DIW ink materials, suboptimal performance of printed products, and challenges in high-volume manufacturability hinder the widespread adoption of DIW technology.This dissertation investigates the current material options for DIW inks and evaluates a series of commercial adhesives and sealants as potential candidates for large-scale DIW 3D manufacturing. Despite their potential, these commercial materials exhibit significant limitations, including prolonged gel and cure times, dimensional instability during curing, and impracticality for commercial manufacturing processes.To address these challenges, this research focuses on developing a PDMS-based two-component (2K) reactive polymeric composite ink. This novel ink formulation offers faster gelation, progressive curing, and dimensional stability, aligning better with scalable DIW manufacturing requirements. Additionally, the study explores the design of derivative DIW inks with adjustable gel times through inhibitor modification, tailored mechanical properties via crosslinker selection, and enhanced thermal and electrical performance by incorporating carbon nanotubes (CNTs).The ability to design microstructures in DIW printing using inks with controlled reaction kinetics, superior mechanical performance, improved elasticity, and enhanced thermal and electrical properties by integrating multiple materials within a single object paves the way for the rapid commercialization of DIW 3D printing. This work provides a foundational framework for the design of next-generation nanocomposite materials for extrusion additive manufacturing, specifically targeting embedded ink writing (EIW) and DIW applications.
