3D Printed Orthotics
From: University of Michigan - MichEpedia

One in three American households has a person using some type of orthotic
device. Orthotics can range from a foot brace aiding a person unable to
complete their walk cycle successfully, to a person needing wrist support for
their carpal tunnel syndrome. Currently it can take up to two weeks from
diagnosis to treatment for these individuals to receive their orthotics. In
the interim they often can accrue costs from lengthy hotel stays if not
located near a large hospital, costs for travel and food over that period,
and have to take that amount of time off from work. Michigan Engineers are
working on a new 3D printing method that can potentially reduce this
fabrication process to a one day visit for patients. This new method changes
the traditional way that items are 3D printed, making parts lighter while at
the same time drastically reducing production time without sacrificing
strength or flexibility.
