“…Another flourishing field of application for 3D printing is the provision of support for surgery planning using physical models of the body or fragment of the osteoarticular system in order to practice the most advantageous variant of approach during the operation. This is especially important in complex and unusual cases [2][3][4]. This paper presents the possibility of using physical models of bones obtained using 3D printing Fig.…”

Abstract. 3D printing is an advanced manufacturing technology which is developing rapidly in near thirty years. Its advantages lie in simplifying producing process, reducing material waste, lowering production costs and meeting the spacial needs of different customers. At present, 3D printing is widely applied in various fields, such as mold manufacturing industry, aerospace, medial treatment etc. In this paper, the working principle and classification of 3D printing technology are elaborated in detail, the exiting problems are analyzed and the application trends of 3D technology are prospected in further.

“…Applying these concepts, the medical industry has been mentioned in papers such as (Otawa et al 2015;Sutradhar et al 2014;Yamada et al 2014) however the collaborative design is something that hasn't been taken into the mass customization conceptual space mainly the speed of converting medical imaging data to usable CAD file for use in additive manufacturing. With the use of 3D scanning and increased software and 3D printing capabilities, these concepts can be applied.…”

3D printing is a manufacturing technique by which the material is added layer by layer to create a physical three-dimensional object. This manufacturing technique had primarily found uses in academic and commercial sectors for prototyping and product realization purposes. However, more recently the home consumer market has seen a surge in low cost printers bringing this capability to the masses. More recently 3D printing has seen considerable interest from the clinical sector, where alongside the synergistic use with medical imaging data, a whole generation of patient specific implantable technologies, splints/casts and resection guides can be created. Predominantly, clinical applications have focused on the use of 3D printing for bone replacement, however with the advent of more sophisticated multi-material printers, interest has now begun to move to applications in orthotics and orthopedic casting.This study is to review and evaluate the feasibility of designing and realizing a more patient specific orthopedic cast to surpass current limitation with traditional fiberglass/plaster casts, through the use of advanced 3D modelling and printing techniques. To directly compare the efficacy of the traditional and 3D printed casts, we shall investigate critical parameters such as the time for manufacture, the overall weight of the final product, the accuracy off the cast relative to the patient’s unique anatomy and additional user-centric metrics (comfort, aesthetics, etc.). The design examined made use of advanced mesh structures throughout the bulk of the cast, such that the device would require less material (by weight) during fabrication, could allow for tunable weight and mechanical properties and allow for air penetration to the person skin, thereby reducing discomfort due to prolonged moisture exposure (chaffing, bad smells, etc.). As the primary focus of this study is the design and product realization phases and we shall not assess metrics relating to patient recover time or experience.Overall it was found that the 3D printed cast was significantly lighter, with improved water repellent and air circulation properties, as compared to a traditional cast. Through the use of high precision design/manufacturing techniques, the final device could be accurately reproduced to match the test patient’s unique anatomy, thereby optimizing the orientation of the patient’s bones during post fracture recovery. It was however found that the manufacturing time for the 3D printed cast was slower than traditional casting methods owing to the additional time during the design phase. In future work we aim to address this limitation and to devise a streamlined methodology such that a generic cast design can be adapted to patient specific anatomical data through parametric design algorithms.Ultimately, it was found that through the use of advanced design techniques, patient specific data and 3D printing, a custom orthopedic cast could be realized and with significant potential to augment current use of this technology for surgical intervention and improve patient outcomes. The use of advanced manufacturing in the medical field will likely enable more patient specific/user-centric treatment in the near future.
