This study investigates the enhancement of polylactic acid (PLA) properties through incorporation graphene nanoplatelets (GNPs) and carbon black (CB) for applications in 3D printing injection molding. The research reveals that GNPs CB improve electrical conductivity PLA, although remains within insulating range, even with up to 10% wt nanoadditives. Mechanical characterization shows nanoparticle addition decreases tensile strength due stress concentration effects, while dispersants like polyethylene glycol enhance ductility flexibility. compares materials processed by molding printing, noting yields isotropic properties, resulting better mechanical properties. Thermal analysis indicates influence crystallization behavior PLA small changes melting behavior. Dynamic Analysis (DMTA) results show how glass transition temperature fluctuate. Overall, nanoadditives into holds potential enhanced performance specific applications, though achieving optimal conductivity, strength, thermal requires careful optimization type, concentration, dispersion methods.
