Prosthetic Limb - Open source

Recommended Posts

I have done a few!

Ignore the poor journalism in the first one - I was not happy with the intial design and so completely re-designed from the ground up (except the excellent 'talon' hand)

We could always use some more UK makers - currently we have other europeans (and thanks to them) helping to satisfy the demand!

I struggled with that to begin with - but they have a wrist and no fingers. Once you accept that - where do you put an exoskeleton except on the outside, and then once you accept it is on the outside - and you are making it with a 3d printer then there is a minimum thickness of material - and a bit extra (as these work for all ages) and then spare because you are bolting and screwing into the stuff and voila - you have this thickness.

So it is the nature of an exoskeleton because most of the actual hand it still there.

If you look at the first one though - the arm - it is matched in length and width to his other arm and hand - because I could - the exo is around his upper arm and elbow.

The great think about open source though s that there are many minds working on these designs - the recipient int he case of the black one actually chose this one as his favorite - and I sent sizing templates so he really knew and I made it as fitted as possible!

But do think on and any suggestions always welcome!

    • Architect Design Contest | People
      The goal of this contest is to design a set of people figurines that could be used in such a project to make an area, office or mall seem populated. 
      Think of different types of people in different environments, like walking people, people standing still, working people, and both men and women.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
