This chapter delves into the advanced realm of additive manufacturing (AM) applied to elastomers, focusing on their unique properties, historical significance, and modern technological applications. Elastomers, particularly natural rubber (NR), have been integral to manufacturing since the 16th century, exhibiting remarkable flexibility, elasticity, and resilience due to their viscoelastic polymer chains. As the field of AM progresses, new possibilities for elastomers in creating complex, detailed components have emerged. Techniques like VAT photopolymerization (VAT) and extrusion-based 3D printing have expanded the versatility of these materials in industries ranging from healthcare to automotive. The chapter explores the evolution of AM technologies, from the early developments in rapid prototyping to modern methods like fused deposition modeling (FDM), digital light processing (DLP), and direct ink writing (DIW). These advancements have unlocked new potentials for elastomers, enabling customized, precise part fabrication with reduced waste. Challenges such as high viscosity in photopolymer resins, adhesion issues, and material compatibility are discussed, alongside the strategies to overcome them, including the incorporation of fillers, cross-linking methods, and rheological control. Furthermore, the chapter highlights ongoing research in optimizing elastomer formulations for improved mechanical properties and the development of advanced elastomeric materials for specialized applications in additive manufacturing.
