Additive manufacturing techniques for protective devices

A protective device for an upper extremity post-operative residual limb of a user manufactured using additive manufacturing, the protective device comprising:

• a multi-section shell comprising a shape that corresponds to an anatomical structure of the upper extremity post-operative residual limb of the user;
• a hinge coupled with a first section and a second section of the multi-section shell, the hinge configured to facilitate relative rotation of the first section and the second section to transition the protective device between an open configuration and a closed configuration;
• a single attachment engagement portion configured to receive one or more attachments to increase functionality of the upper extremity post-operative residual limb of the user;
• wherein the multi-section shell has a wall thickness that varies spatially along the multi-section shell, the wall thickness at a particular location being based on a corresponding amount of expected stress to be experienced by the multi-section shell at the particular location during use of the protective device, wherein the variable thickness enables a desired corresponding flexion at the particular location, the multi-section shell having a shape modified from a scan shape associated with a scan of the upper extremity post-operative residual, wherein the multi-sectional shell comprises a foam layer extending along an entirety of an interior of the multi-section shell and configured to directly abut the upper extremity post-operative residual limb of the user.
