Additive manufacturing of multifunctional polylactic acid (PLA)—multiwalled carbon nanotubes (MWCNTs) nanocomposites

In this work, an industrially scalable method was developed for the preparation of multifunctional nanocomposite filaments. Polylactic Acid (PLA) polymer matrix was enriched with Multi Wall Carbon Nanotubes (MWCNT) at various concentrations, to fabricate 3D-printed parts by the Fused Filament Fabric...
