“I deeply believed in this kind of technology,” Avaro explained. “When I got in contact with WASP I really found a jewel: the printer was perfect for my job. It allows me to realize very big pieces, of over 40 centimeters at a time. The quality is so high that I don’t have to process the plastic [afterwards]. The printing speed is very high as well, and the structure of the machine permits me to reproduce wafer-thin shells. There are several benefits.”
3D printing has allowed Avaro to completely customize each prosthetic leg to a degree previously not possible. He says that this has been especially helpful in cases of degenerative illness in patients, where their leg stumps become very asymmetric.
During the production of the prosthetic legs, the 3D printed plastic holds up extremely well and actually allows for a better overall fabrication of the devices.
“The DeltaWASP 20×40 prints brilliantly, [and was able to] overcome the destructive tests and the calculation tests with accomplished elements,” explained Avaro. “This makes it possible to realize a resistant structure which is much more lightweight.”
It’s not just the functionality of the 3D printed parts that have Avaro excited. He also says that the aesthetics of it are better than more traditional prostheses. The 3D printed plastic is able to be polished, which leaves the prosthetic leg with a shiny, rich look.
Most importantly though, these legs are made on an individual level for each and every patient, meaning they fits perfectly, and are extremely comfortable to wear.
“The printer is so fast,” said Avaro. “To realize a tibial prosthesis I [previously] needed eight hours, now I can make it in two. I have the chance to realize prostheses for the ones who practice specific sports like mountain climbing. I finish the prosthesis, deliver them and there is never need for any revisions. Physiotherapists that follow the rehabilitation are amazed [at] what we do. [Discovering] WASP changed my work, and consequently my life.”
I feel as though we are really on the brink of highly advanced prostheses, thanks to 3D printing technology. It should be interesting to see what other advancements occur in the coming months and years ahead. What do you think about these prosthetic legs?
