“…The advantages of 3D printers are that they are easy to model, fast to manufacture, and cost-effective in production, making 3D printers very appropriate to be used as an alternative to orthoses (Choi et al, 2019). The use of finite element analysis can predict critical areas of a model so that the model design can be improved and refined before being fabricated (Qosim et al, 2020(Qosim et al, , 2022.…”

Other than surgery, post-stroke spasticity, fractures due to accidents, sports injuries, and musculoskeletal disorders due to office work on the wrist can be treated using a wrist-hand orthosis. The customized conventional methods usually have some drawbacks, which are more expensive, take a long time to manufacture, and require expert skills from medical therapists. The presence of reverse engineering (RE) technology can be applied in the medical field, such as the manufacture of prosthetic or orthosis devices. This study aims to develop a reverse engineering-based wrist-hand orthosis design, analyze it using the finite element method, and fabricate it. Research methods included 3D scanning, CAD modelling, model analysis, 3D printing, and postprocessing. The model material used was PLA with variations in the thickness of 5 mm, 5.5 mm, and 6 mm, and the load values range from 0 N to 30 N. The results of the equivalent stress analysis showed that the 5 mm thickness model could withstand a load of 30 N with a maximum equivalent stress of 23.46 MPa. With a safety factor value of 2.56, it was still relatively safe, and a critical area was at the back end of the model's palm between the thumb and index finger. The equivalent elastic strain and deformation results also had the same graphic trend with the maximum values for the same model, which were 0.0076 mm and 0.614 mm, respectively. The 3D printing FDM result showed that the Voronoi perforated wrist-hand orthosis prototype was sturdy, fit, and comfortable. It is expected to hold muscle tone and immobilize for hand rehabilitation.

“…Keunggulan 3D printer adalah mudah dalam modelling, cepat dalam pabrikasi, dan hemat biaya produksi menjadikan 3D printer sangat tepat digunakan sebagai alternatif pembuatan orthosis [17]. Penggunaan finite element analysis dapat memprediksi area kritis suatu model sehingga desain model dapat ditingkatkan dan disempurnakan sebelum difabrikasi [18], [19]. Oleh karena itu, perlu adanya penelitian lebih lanjut tentang pembuatan wrist-hand orthosis dengan menggunakan teknologi reverse engineering (RE) dan rapid prototyping (RP) yang lebih nyaman, kokoh, dan mudah dalam pemasangan dan penggunaan.…”

Salah satu treatment untuk spasticity efek pasca stroke, fracture karena kecelakaan, injury karena cedera olahraga, dan musculoskeletal disorders karena pekerjaan kantoran pada pergelangan tangan selain dengan operasi yaitu dengan penggunaan wrist hand orthosis. Umumnya pembuatan medical device tersebut menggunakan metode konvensional yang mempunyai kekurangan. Hadirnya teknologi reverse engineering (RE) dapat diaplikasikan dalam bidang medis seperti pembuatan alat prosthetic atau orthosis. Pada penelitian ini bertujuan untuk mengembangkan desain wrist hand orthosis berbasis reverse engineering dan menganalisisnya menggunakan metode elemen hingga. Metode penelitian meliputi 3D scanning, CAD modelling, model analysis, dan post processing. Material model yang digunakan adalah ABS dengan variasi ketebalan 5 mm, 6 mm, dan 7 mm, serta besar nilai pembebanan mulai dari 5 N sampai 25 N. Hasil analisis equivalent stress menunjukkan model ketebalan 5 mm mampu menahan load 25 N dengan maximum equivalent stress sebesar 13.52 MPa yang masih tergolong aman dengan nilai safety factor 2.11 dengan area kritis di ujung punggung telapak tangan model antara ibu jari dan jari telunjuk. Hasil equivalent elastic strain dan deformation juga mempunyai tren grafik yang sama dengan nilai maximum pada model ketebalan 5 mm yaitu masing-masing sebesar 0.0057 mm dan 0.616 mm. Dari hasil analisis tersebut dapat disimpulkan bahwa model wrist hand orthosis berlubang voronoi yang memiliki bentuk seperti surface tangan manusia dengan ketebalan minimalis 5 mm mampu bekerja dengan baik memfiksasi tangan pasien untuk proses rehabilitasi.
