We designed a functional yet life-like prosthetic finger that is able to fit and support users in the handling of simple daily tasks. Traditional passive cosmetic prosthetic fingers are not functional and they get in the way when users are handling their daily tasks, sticking out awkwardly due to its lack of articulation. With the incorporation of a simple mechanism, the new prosthesis is able to lock in specific positions and support the user in their daily tasks. As an entire commercial (production) process, this project seeks to re-invent the relatively stagnant field of ‘passive cosmetic prostheses’ through the use of 3D technology, turning a craft process into a digital process that is fit for mass customization. The efficiency of the laborious traditional making process is improved, making it more economical and sustainable through the reduction of material wastage and the digitalisation of information, ultimately lowering costs to make it affordable for the masses.
