3D printing helps individuals who are missing their hands to obtain a cheap, reliable, customizable, prosthetic which can be constructed almost entirely from 3D printed parts. It has helped better the lives of hundreds of individuals from children in war torn Sudan, to adults in the United States. Unlike traditional prosthetic devices offered to patients, which can cost well over $25,000, the 3D printed prosthetics can be printed out on a 3D printer for around $50, which is still a bargain compared to the alternative.
A 3D printed leg prosthetic is much more difficult to create because the typical ABS or PLA plastic used with FDM based 3D printers generally lacks the strength to hold the weight of an average sized human being, over an extended period of time.
3D printed prosthetics allow for important knee and ankle movement, and appears to be relatively light-weight compared to its size. It will resultin the accessibility and convenience of prosthetic devices for amputees. Varying adjustments can be made for people of varying heights.
