This paper attempts to determine whether hobbyist 3D printers can be used to advance prosthetic capabilities. We attempt to answer this by designing, printing, and testing a prosthetic hand using a hobbyist 3D printer and hobbyist materials. The prosthetic hand with an opposable thumb was drafted from scratch and 3D printed collectively across four different fused deposition modeling printers; A Craftbot Plus Pro, CR-10, Jgaurora, and Qidi X-Plus. Once assembled, a material study was conducted against three different materials to identify the plausibility of sensing force using the materials piezoresistivity. Piezoresistivity is a measurement of resistance when a mechanical strain is applied. It was concluded that touch sensing capabilities could be utilized with 3D printed materials while on a hobbyist grade 3D printer. None of the materials required a heated chamber however, the argument of a heated bed improving the printability is undeniable. The likelihood of successfully incorporating this function into a 3D printed prosthetic had immense potential and promise.
