3D Printing in LMICs: functional design for upper limb prosthetics in Uganda

Meeting the needs of persons with upper limb loss in Uganda requires an understanding of the needs and desires of the local population. The limitations of resources and accessibility for the individual gave rise to a focused design methodology for delivering a culturally acceptable solutionusing 3D Printing technology. A series of co-design activities were held in Uganda and provideddirect feedback to drive the design of two prototypes based on acceptable aesthetics and priorityActivities of Daily Living. Two terminal device prototypes were 3D printed in the UK. These can bedirectly attached to a standard proximal socket thread. The passive hand was printed in a flexiblefilament and the prehensor was printed in a durable impact resistant material. Local researchers inUganda have similar 3D printers, filaments, and assembly hardware, which allowed for concurrentdevelopment and refinement of the prototypes. Local participation provides a rich user feedbackenvironment to understand which elements of prosthetic device design are integral to deliveringacceptable prosthetics solutions for fabrication in Uganda. 3D printing can provide a viable routeto addressing the needs of the user. The proposed terminal devices are now in the process of beingprinted locally for field testing
