A polylactic acid (PLA) composite material includes biodegradable and/or renewable materials such as purified lignin recovered as a byproduct in organosolv processes. The result is a material suitable for additive printing, with improved properties but that is still environmentally friendly. A coupling agent such as silane, diisocyanate crosslinking agent, and reactive extrusion agent may improve the blending of polylactic acid and purified lignin. Additional filler materials such as fibers or their powders may be added to significantly improve the mechanical properties of three-dimensional printed objects.
