Researchers from the Oak Ridge National Laboratory's Materials Science and Technology Division developed a composite 3D-printer filament made from lignin, acrylonitrile-butadiene-styrene polymer, carbon fiber and rubber. Their study "offers a route toward utilizing lignin for replacement of petroleum-based thermoplastics used in additive manufacturing and methods to enhance printability of the materials with exceptional mechanical performance," the authors say.
