Experimental Evaluation of Characteristics in Large-Scale 3D-Printed Structures from Wood-Based Polymer Composites

Abstract This study investigates the mechanical and physical properties of a wood-based polymer composite DuraSense® 3D S50 Flex K to enhance its potential in large-scale additive manufacturing by studying the influence of printing orientation on the mechanical characteristics of the product. To assess performance, the specimens were produced with different printing layer orientations: at 0°, 30°, 45°, and 90° to the sample length, which corresponds to load application during the tests.
