Abstract Elastomers are a versatile and vital category of polymers with applications across numerous sectors, including automotive, healthcare, aerospace and consumer products. In recent times, elastomers have been produced through additive manufacturing techniques, allowing for the production of intricate and highly functional components. Despite the advantages, additive manufacturing remains challenging due to the inherent thermal and mechanical properties of elastomers. This review delves into the production of elastomers through additive manufacturing methods such as fused deposition modeling, stereolithography, selective laser sintering and direct ink writing. Each method is examined regarding its material compatibility and applicability in manufacturing the elastomer components. The objective of this review is to present the current status of elastomer additive manufacturing with an emphasis on major constraints and limitations faced in the domain. It goes on to examine the evolution of the processes and provides useful recommendations on future strategies that will enhance elastomer printability, to assist researchers and practitioners in the industry in identifying new and creative applications of additive manufacturing.
