This paper discusses the possibilities of obtaining polylactide-based composites and nanocomposites modified with carbon materials using the extrusion method, as well as the potential of their application in 3D printing technology. The aim of this research is to determine the impact of the presence of carbon additives on the properties of composites: mechanical, thermal and chemical. For this purpose, several research techniques were used such as scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), DSC/TG analysis, infrared Fourier-transform infrared spectroscopy (FTIR) and mechanical tests. It has been shown that it is possible to effectively produce composite materials based on PLA and carbon modifiers after optimization of the extrusion and printing process. Special attention should be paid to the quality of carbon phases homogenization in PLA matrix because the inappropriate dispersion may have a negative effect on the final properties of the composite, especially those modified with nanomaterials. Moreover, the reinforcing effect of carbon phases can be observed, and the quality of obtained filament with carbon fiber after recycling does not differ significantly from the quality of commercially available filaments. The obtained filament was successfully used to print three-dimensional scaffolds. Therefore, both the use of materials which are biodegradable and biocompatible with human tissue and the 3D printing method have the potential to be applied in tissue engineering.
