In the recently published ‘ Antioxidant PLA Composites Containing Lignin for 3D Printing Applications: A Potential Material for Healthcare Applications ,’ Belfast researchers experiment with new 3D printing materials.
Due to its strength as a biopolymer and an antioxidant, the research team combined lignin with poly(lactic acid) in FDM 3D printing. Scheme of the different meshes produced using FFF. Coating PLA pellets with LIG powder and castor oil, which is biocompatible, they extruded the material at 200 °C. The researchers reported LIG loadings that ranged from 0% to 3% ( w / w ). With the goal of providing additional, beneficial features to PLA, the research team tried varied strategies, to include incorporating molecules with antioxidant properties to PLA.
“The unrestrained production of free radicals and reactive oxygen species is linked with the onset of diseases such as rheumatoid arthritis, atherosclerosis or cancer,” stated the researchers. “Accordingly, the development […]
