Wood-Based Polymer Composites for Additive Manufacturing: Influence of Printing Strategy on Product Properties

Article Preview

Abstract:

In this research, the wood-based polymer composite DuraSense® 3D S51 Flex K, composed of 50% wood fibers and 50% polymer, was studied for the manufacture of products using large-scale additive manufacturing technology. Experimental specimens were produced to determine composite properties and the influence of printing strategy on these properties. The study involved creating test samples in four different printing orientations relative to the horizontal axis: 0°, 30°, 45°, and 90°, that is using different printing strategies, which affected the mechanical properties of the products. All sample types were tested for density, tensile strength, flexural strength, and underwent microscopic investigation. The test results demonstrated sufficient mechanical properties and durability of the obtained products, and enabled evaluation of the relationship between printing strategy and the strength characteristics of the products. It was found that the mechanical properties of products obtained by 3D printing are lower than those of the raw materials (granulate for additive manufacturing) as declared by the manufacturer. This is explained by structural changes, specifically the formation of micropores and the reduction of interlayer bonds during large-scale additive manufacturing. Considering the determined strength and durability indicators, as well as the advantages of additive manufacturing technology, the use of wood-based polymer composites is recommended for the production of various products using 3D printing.
