Online community of 10,000 people worldwide who voluntarily use their 3D printers to create hand and arm prostheses for adults and children who need it.

Individuals and organizations who wish to collaborate with the cause access the web to find users from more than 100 countries who need a prosthetic and have posted photographs showing and explaining the required prosthetic. The voluntary, then, contacts this person, downloads all the necessary information from the website, and adapts the available designs, which are in open source and free of rights, to the specific need of the person who will benefit. Once the prosthesis is printed, the voluntary person disinterestedly forwards it to the final beneficiary, who often lives in another country or continent.

In this way, through domestic manufacturing technology, people with low resources who cannot access a prosthetic because of their high price and/or the need to adapt them to children’s growth can have a free and customised prosthetic.
As an online portal, each can connect with people demanding from all over the world, although also can easily find plaintiffs living nearby and deliver the prosthetic to them personally.
