description In recent years, the composite nanomaterials area has had a great development impact in health sciences. Biomaterials depict as one of the most promising since they are compatible with additive manufacturing (AM) techniques. It is also possible to use them to mold specific medical parts. Composite nanomaterials have shown good biocompatibility and low toxicity to have benefits equal to or greater than metals (i.e., Co-Cr alloy). The purpose of this study is to develop a nanocomposite biomaterial (PLA/MWCNTf) from Polylactic Acid (PLA) and functionalized Multi Walled Carbon Nanotubes (MWCNTf) to evidence its potential application in 3D printing of orthopedic fixation devices. PLA/MWCNTf nanocomposite was prepared by solution blending technique, incorporating a proportion of 0.5 wt% of MWCNTf to the PLA matrix. TGA analysis of the PLA/MWCNTf was used to determine the thermal stability, a slight increase was found compared to the PLA.  FTIR spectroscopy confirmed the presence of carboxylic acid groups in the MWCNTf which improves good incorporation of the nanotubes in the PLA matrix. Additionally, Raman spectroscopy, SEM, and AFM micrographs were used to verify MWCNTf reached the PLA surface homogeneously. Additive manufacturing preparation was done by extrusion molding of PLA/MWCNTf as well as its 3D printing.

Los biomateriales se describen como uno de los más prometedores, ya que son compatibles con las técnicas de manufactura aditiva (AM). También es posible utilizarlos para moldear piezas médicas específicas. Los nanomateriales compuestos han demostrado una buena biocompatibilidad y baja toxicidad para tener beneficios iguales o superiores a los de los metales (p. ej. aleación de Co-Cr). El propósito de este estudio es desarrollar un biomaterial nanocomposito (PLA/MWCNTf) a partir de ácido poliláctico (PLA) y nanotubos de carbono multi pared funcionalizados (MWCNTf) para evidenciar su potencial aplicación en la impresión 3D de dispositivos de fijación ortopédica. El nanocomposito de PLA/MWCNTf se preparó mediante la técnica de mezclado en solución, incorporando una proporción de 0,5% en peso de MWCNTf a la matriz de PLA. Se utilizó el análisis TGA de PLA/MWCNTf para determinar la estabilidad térmica, se encontró un ligero aumento en comparación con el PLA. La espectroscopía FTIR confirmó la presencia de grupos carboxilos en los MWCNTf lo que mejora una buena incorporación de los nanotubos en la matriz PLA. Además, se utilizó espectroscopía Raman y SEM para verificar que MWCNTf alcanzara la superficie de PLA de manera homogénea. La preparación de la manufactura aditiva se realizó mediante moldeo por extrusión de PLA/MWCNTf así como su impresión 3D.
