The Thermal and Mechanical Behaviour of Wood-PLA Composites Processed by Additive Manufacturing for Building Insulation

This study was aimed at considering the potential of wood-based composites processed using additive manufacturing as insulators in building sector. A polylactic acid blend with 30% wood particles used a feedstock material fused filament technology. Its thermal and mechanical properties were determined for various processing conditions, including printing temperature infill rate. The results showed minor contraction its tensile performance result process. had negligible effect on stiffness limited influence other engineering constants, such strength ultimate stress. printed structures have been found to significantly depend Although tested 3D wood-PLA exhibited good properties, which tuneable still 38% 57% lower compared glass wool synthetic foams
