However, their mechanical properties\nand behaviour remain difficult to model due to the anisotropic and heterogeneous shell–\ninfill architecture. Despite increasing clinical use, validated modelling frameworks are still\nlimited. This study developed and validated a multi-scale finite element (FE) framework for\n3D-printed orthoses with experimental testing.\n\nMethods: Orthotropic infill properties were derived via numerical homogenization and\ncombined with isotropic shell properties in a hybrid FE model. At the microscale, tensile\nand compression tests of standardized 3D-printed specimens were compared with FE\npredictions. Sensitivity analyses were conducted to assess the structural contributions of\nthe shell and infill on overall stiffness. At the mesoscale, experimental nonhomogeneous\nstrain distributions in organic subunits were analysed using digital image correlation and\ncompared with FE simulations. At the macroscale, the model’s predictive accuracy was\nevaluated against full-brace experimental data.\n\nResults: The hybrid FE model accurately reproduced elastic behaviour in both tension and\ncompression, with stiffness differences of 1.8% and 3.7%, respectively. Sensitivity analysis\nconfirmed the dominance of shell stiffness over infill but also the need to represent both\ncomponents within the hybrid model. Mesoscale validation showed close agreement between experimental and simulated strain fields (82% histogram overlap). At the macroscale, predicted reaction forces deviated by less than 2% from averaged experimental measurements, and stress analysis identified regions consistent with observed plastic deformation.\n\nConclusions: The validated framework enables accurate and computationally efficient FE\nmodelling of 3D-printed orthoses, supporting performance-driven design by redistributing\nmaterial based on stress while maintaining structural functionality. This approach facilitates lighter, more breathable, and patient-compliant brace designs. Beyond scoliosis treatment, the methodology is broadly applicable to orthotic, prosthetic, and other lattice-based engineering structures."},"dsDescriptionDate":{"typeName":"dsDescriptionDate","multiple":false,"typeClass":"primitive","value":"2026-02-23"}}]},{"typeName":"subject","multiple":true,"typeClass":"controlledVocabulary","value":["Medicine, Health and Life Sciences"]},{"typeName":"keyword","multiple":true,"typeClass":"compound","value":[{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"Adolescent Idiopathic Scoliosis, mechanical testing, bracing"}}]},{"typeName":"language","multiple":true,"typeClass":"controlledVocabulary","value":["English"]},{"typeName":"producer","multiple":true,"typeClass":"compound","value":[{"producerName":{"typeName":"producerName","multiple":false,"typeClass":"primitive","value":"Hoelen, Thomáy-Claire"},"producerAffiliation":{"typeName":"producerAffiliation","multiple":false,"typeClass":"primitive","value":"maastrichtuniversity.nl"}}]},{"typeName":"distributionDate","multiple":false,"typeClass":"primitive","value":"2026-02-23"},{"typeName":"depositor","multiple":false,"typeClass":"primitive","value":"Vivas Romero, Maria"},{"typeName":"dateOfDeposit","multiple":false,"typeClass":"primitive","value":"2026-02-23"}]},"dansDataVaultMetadata":{"displayName":"Data Vault Metadata","name":"dansDataVaultMetadata","fields":[{"typeName":"dansDataversePid","multiple":false,"typeClass":"primitive","value":"doi:10.34894/8MMZM4"},{"typeName":"dansDataversePidVersion","multiple":false,"typeClass":"primitive","value":"1.0"},{"typeName":"dansBagId","multiple":false,"typeClass":"primitive","value":"urn:uuid:4819df0c-afb7-4c80-88b7-98566c08cfb0"},{"typeName":"dansNbn","multiple":false,"typeClass":"primitive","value":"urn:nbn:nl:ui:13-4d670aba-d261-4ca1-a052-bbfbe17beb6f"}]}},"files":[{"label":"Supplementary Materials Chapter 4.2.pdf","restricted":false,"version":1,"datasetVersionId":34070,"dataFile":{"id":611855,"persistentId":"","filename":"Supplementary Materials Chapter 4.2.pdf","contentType":"application/pdf","friendlyType":"Adobe PDF","filesize":353223,"storageIdentifier":"surf://store:19c8c986848-8473c8b54e22","rootDataFileId":-1,"checksum":{"type":"SHA-1","value":"a0aa8a3f6d91f91860d89eef84aaf856ccc5f5fa"},"tabularData":false,"creationDate":"2026-02-23","publicationDate":"2026-02-25","lastUpdateTime":"2026-02-25T14:03:05Z","fileAccessRequest":true}}]}}}
