Background Before launching a new bespoke foot orthotic (FO) product, it is necessary to understand how it works under compressive loads. Additive manufacturing and the selective laser sintering process in particular can enable a number of innovative and functional features to be integrated to the FO device. A simple example of this design freedom is to adjust the shell thickness of an FO. This research is an effort to measure the displacement of the arch as the FO is loaded with a certain force and how much different FO shell thicknesses impact the amount of displacement with the same load.
