Mario was born with a malformation in his right arm that prevented him from performing everyday movements like unbuttoning his clothes. But what weighed on him most was not the lack of functionality, but the insecurity of showing his body in public. Thanks to a 3D-printed prosthesis, designed by a team of engineers and doctors, Mario not only regained mobility but also stopped hiding. A story of how accessible technology can change the way we see ourselves.
Custom design: when engineering imitates nature 🛠️
Mario's prosthesis is not a generic arm taken from a catalog. It was manufactured using 3D printing after scanning his stump and modeling articulated pieces that mimic the movement of a real hand. The engineers used PLA filament, a cheap and lightweight material, and added a system of cables that tighten when bending the elbow. The result: a device that allows grasping objects and, most importantly for Mario, unbuttoning buttons with precision. All at a cost much lower than that of a traditional prosthesis.
The drama of taking off a t-shirt at the pool 🏊
If for many, taking off a t-shirt at the beach is an act of bravery (because of a belly or lack of abs), for Mario it was an ordeal ending in embarrassment. Now, with his 3D prosthesis, he takes it off with the same ease as a runway model. Of course, he still can't tie a necktie blindfolded, but at least he no longer has to ask his mother for help every time he goes to the pool. Technology doesn't work miracles, but it does avoid awkward moments.
