Three-dimensional printed orthosis in biomedical application: A short review

The three-dimensional (3D) printing in medical implants unlocks unparalleled opportunities to completely configure the product to the patient's measurements and needs. To be noted, the use of personalized 3D printed orthosis used in regeneration for serious orthosis implants of specific patients is growing to date. The 3D printed is unique to the patient instruments that can be used to facilitate correct positioning of implants and improved functional outcomes. The 3D printing, also defined as 'rapid prototyping' and 'additive manufacturing’ is widely regarded as the ‘second technological revolution. The orthosis is an "externally applied mechanism used to alter the structural and functional properties of the musculoskeletal and skeletal system". Applications in orthosis healthcare that are pioneering the way 3D printing is performed, changing the orthosis implant markets. This paper is reporting literature on the development of orthosis using 3D printing technology that could make the users more comfortable and easier to maintain. From the literature search, this paper summarises some important information about the use of 3D printing for orthosis development where it focusses on specific regions of human body, the materials for the 3D printed orthosis and further directions of this technology and research. In conclusion, the findings from this review paper may lead to a future recommendation and study in providing better treatment for patients.
