20.500.12556/RUL-137812 Strength and stiffness of 3D-printed connectors compared with the wooden mortise and tenon joints for chairs In this study, 3D-printed connectors to replace the typical L-shaped joints in the construction of a chair were developed, tested and numerically analysed. Different connectors were designed and manufactured with a fused deposition modelling (FDM) 3D printer using acrylonitrile butadiene styrene (ABS) with the aim to find a simple shaped connector which could be used to build chairs and withstand standard chair loading requirements. The strength and stiffness of the joints were tested and compared with traditional beech mortise-and-tenon joints. Numerical stress and strain analyses were performed with the finite element method for an orthotropic linear-elastic model. The experimental results showed that joints with 3D-printed connectors achieved lower strength than the traditional wooden mortise-and-tenon joints with similar dimensions. The results indicate that the effect of reinforcement of the connector were not recognised due to the small thickness and inadequate geometric position and arrangement of the reinforcement ABS material. The chair assembled with 3D-printed connectors could withstand the loads for seating, but failed the backrest test according to standard EN 1728:2002. The connectors need to be optimised and reinforced to withstand standard loads. wood mortise-and-tenon joint 3D printing strength stiffness les čepne vezi 3D tiskanje true false true Angleški jezik Slovenski jezik Članek v reviji 2022-07-01 10:47:13 2022-07-01 10:47:17 2023-06-15 03:43:11 0000-00-00 00:00:00 2023 0 0 Str. 870–883 no. 3 Vol. 18 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*8 1748-0280 10.1080/17480272.2022.2086065 112170755 Strength_and_stiffness_of_3D_printed_connectors_compared_with_the_wooden_mortise_and_tenon_joints_for_chairs.pdf Strength_and_stiffness_of_3D_printed_connectors_compared_with_the_wooden_mortise_and_tenon_joints_for_chairs.pdf 1 3164AA323F53325F4347DD9E09E2A846 d9f45d21ecb489fa74a089797bbd46d9cb384182675ae9ea5da50f5baea40fa9 1d3697fa-0ab8-11ee-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=170130 https://www.tandfonline.com/doi/full/10.1080/17480272.2022.2086065 1 36214603-f91a-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=157895 Biotehniška fakulteta Fakulteta za arhitekturo 0 0 0
