There is high interest in sustainable polymers and promoting a circular plastics economy even through upcycling. The emphasis is typically on the de novo chemistry of new polymer design and the use of lignocellulosic intermediates. This paper will emphasize on renewable nanomaterials and biobased feedstocks or derived natural raw materials for use in 3D printing and additive manufacturing (AM). AM has enabled the use of high volume of polymers and bio-inspired materials including cellulose nanocrystals (CNC) and cellulose nanofibers (CNF) for polymer nanocomposites. These materials improve thermo-mechanical properties and processability. In this talk, we will focus on the use of CNC derived from two sources: Abaca and coconut fibers. We will also focus on chitosan-derived cellulose materials (nanowhiskers and complex-surfactant additives). The mode of raw materials can be from processed pulp or directly from coconut coir. These nanofiller materials have been utilized in two types of applications: nanofiller materials for 3D printed parts via stereolithographic apparatus (SLA) and the preparation of aerogels. Chitosan nanomaterials derived from chitin have advantages in terms of functional group interaction with electrostatic charge pairing. In SLA 3D Printing, they enable improved biocompatibility and complex materials-design development for biomedical applications.
