Conceptually, the design of the Shin Brace project will be made using PETG as the primary material in 3D printing. It is designed on SolidWorks CAD for accurate modeling, where iterative refinements can be made possible in response to user feedback.
PETG would be ideal for this application, as it boasts excellent mechanical properties like durability, flexibility, and impact resistance, which are the basic requirements for a wearable device intended to go through regular rigors associated with physical activities (PETG 2019). Hence, high ductility in tensile properties enables the device to absorb stress without breaking, a very critical factor, especially for those users who take part either in sports activities or in rehabilitation exercises. Additionally, good layer adhesion during printing ensures structural integrity in the 3D-printed product.
On the other hand, PETG is not without its disadvantages. It may be sensitive to UV exposure in time, which, if used outdoors, may affect its durability. Besides, it may require a fine surface finish after post-processing. All these minor disadvantages do not matter much considering the general characteristics of PETG while printing, in particular, flexibility and ability to work with the movement of the user without losing support.
This concludes that the use of PETG in the conceptual design of the shin brace presents a strong solution that comfortably balances durability and functionality, hence being optimal for recovering patients from shin injuries.
