In this study, we introduce a method for modifying poly(lactic acid) (PLA) filament, which is adjustable to enhance the rheological properties and biocompatibility of printed products or impart specific characteristics by bonding nanoparticles onto the surface of graphene oxide. What distinguishes our method is the post-production modification of PLA filament before the printing process. Graphene oxide, being a unique nanomaterial with diverse applications in science and technology, serves as a platform for modification due to the presence of functional groups on its surface that are accessible for binding modifiers or nanoparticles. The persistence of graphene oxide on the surface of printed items even after 3D printing highlights its potential for further modifications. This presence was verified through scanning electron microscopy and Raman spectroscopy.
