A Review on Filament Materials for Fused Filament Fabrication

Fused filament fabrication (FFF) is one of the most popular additive manufacturing (AM) processes that utilize thermoplastic polymers to produce three-dimensional (3D) geometry products. The FFF materials have a significant role in determining properties final part produced, such as mechanical properties, thermal conductivity, and electrical conductivity. This article intensively reviews state-of-the-art for filaments. To date, there are many different types been developed. range from pure thermoplastics composites, bioplastics, composites bioplastics. Different reinforcements particles, fibers, nanoparticles incorporated into composite filaments improve build properties. performance, limitations, opportunities specific type will be discussed. Additionally, challenges requirements production evaluated. In addition, provide concise review fundamental knowledge about filament, this also highlight potential research directions stimulate future development. Finally, importance scopes using bioplastics their developing eco-friendly introduced.
