Cover Story: Lignin is a natural biopolymer with well-known antioxidant capabilities. This molecule is present in the support tissues of vascular plants and provides chemical and mechanical protection from external stresses. In the present work, a method to combine LIG with poly(lactic acid) for fused filament fabrication applications is proposed. By using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method, the materials were capable of reducing the concentration of this compound up to ca. 80% in 5 h. This radical scavenging activity combined with the versatility of 3D printing could be potentially beneficial for healthcare applications, especially for wound care.
