Lignin is the material left over from the processing of biomass. It gives plants rigidity and also makes biomass resistant to being broken down into useful products. Researchers combined a melt-stable hardwood lignin with conventional plastic, a low-melting nylon, and carbon fiber to create a composite with just the right characteristics for extrusion and weld strength between layers during the printing process, as well as excellent mechanical properties.
