Chapter Two provides a comprehensive review of the relevant literature, divided into two parts. Part I presents a thorough examination of cellulose resources, covering types, production processes, resulting products and their impact in the field. In this section, the specific type of cellulose used in the research is identified and the different types are distinguished according to the production process. Part II focuses on the use of cellulose as a paper-based material within additive manufacturing (AM) technology. It provides a detailed overview of its various applications and discusses primary strategies to overcome the challenges involved. It also explores conceptual frameworks aimed at unlocking the potential of paper-based materials to achieve specific goals within AM processes. The motivation behind the research and its main objectives and contributions are summarised.
