Polymeric Compounds with Cellulose Nanofibrils for 3D Printing Applications

Abstract

<div class="section abstract"><div class="htmlview paragraph">A systematic review based on the PRISMA protocol was used to evaluate compounds developed for 3D printing with the incorporation of cellulose nanofibrils into polymers to be used in the automotive sector. The processing parameter is a data of great relevance for the development of durable structural parts and this study can be carried out using the state of the art on this subject. This way, the research was carried out using a search strategy from three different databases (Web of Science, Scopus and Science Direct) limiting studies between the years 2019 and 2023. The keywords used in these searches were: "3D Print" OR "FDM" OR "Fused Deposition Modeling" OR "FFF" OR "Fused Filament Fabrication" AND "Natural Nanofiber" OR "Natural Nanofibril" OR "Cellulose Nanofiber" OR "Cellulose Nanofibril". The same criteria described were also used to search for patents on the PatentScope, Google Patents and Espacenet platforms. The difference between the number of articles found for each database is due to the fact that they differ from each other in terms of indexing and presentation of information. Subsequently, screening and exclusion criteria were established and applied on the database before using the software “ASReview” to organize and select the most suitable articles, according to the relevance and adherence on “Cellulose Nanofiber” and “3D Print”. The focus of this study was to present articles that will support the study of the main polymers used in the cellulose nanofibril mixture in relation to the parameters of structural parts obtained by prototyping in order to optimize the printing time, final quality and durability of automotive parts.</div></div>
