Robotic Large-Scale Additive Manufacturing Using Sustainable Lignin-Based Wood Polymer Composites: Physico-Mechanical Investigation, Performance and Anisotropy

The data obtained within the research which explores using large-scale additive manufacturing technology for fabrication of range of products from biodegradable wood-based polymer composite on lignin and softwood fibre. The study was caried out by the method of determining the main physico-mechanical characteristics on the specially made specimens from mentioned composite: tensile strength, flexural strength, hardness, density, water absorption, deformation, thermophysical properties and microstructure using optical and scanning electron microscopes. Influence of printing strategy on the strength of products were determined using variation of samples with printing layers orientation at 0°, 30°, 45°, 60° and 90° to the sample length (direction of test load application).
