Advances in 3D medical printing are quite amazing. Here are some recent articles on 3Ders.Org.
3d Printed Hand
Comparing: $50 3D printed hand vs. $42,000 prosthetic limb
Jose Delgado Jr. Jose, 53 year old, was born without most of his left hand and in the past year, he had been using a prosthetic hand that costs $42,000, which he paid about half out of pocket. This myoelectric version uses the muscle signals in his forearm to trigger the closing or opening of the fingers, like a real hand would.
Jose visited e-NABLE member Jeremy Simon and asked if he could help make a 3D printed prosthesis for him. Created by Jon Schull, a researcher at Rochester Institute of Technology, e-NABLE pairs children and adults with missing or deformed fingers, hands or forearms with makers who produce customized 3D printed prostheses that can improve their lives.
Jose has been using multiple types of prosthetic devices for years, so he’s very familiar with what can or can’t be done with them in terms of day-to-day functionality. To his surprise, Jose said he actually prefers the 3D printed Cyborg Beast to his far more expensive myoelectric prosthesis.
Jose claims that the simple, mechanical design of Cyborg Beast is even more comfortable and provides more day-to-day functionality than the expensive version. And if a piece breaks, he could simply print a new one in a few hours.
A typical prosthetic hand from a company will run you more than $10,000, but materials for a 3D printed hand can cost less than $50. The design, research, development and prototyping time for these 3D printable limbs designs has been donated by many individuals in the e-NABLE community, a group of 700 people globally. The design is open source and thus no rights have had to be purchased to use or make them. Therefore it is possible to produce a partial hand for a cost of less than $50 as compared to a retail device with a price of thousands.
Jeremy says he is working with Jose on printing another new hand and this time using a material called Bridge nylon, which is stronger than the previous material and also light weighted. “I’ll also be providing him with an alternate thumb mount that will enable a different kind of grip.” Jeremy said.
