THE PROBLEM


The need for prosthetic limbs is too great.

  • Millions of children living in poverty are either born without a limb - or have lost an arm or leg due to injury or infection.

  • Each of these children needs several prostheses as they grow.

The resources are too few

  • In Uganda, there are as few as 12 people currently making these prostheses - and each one takes over 6 days to make.

  • The World Health Organization estimates a shortfall of 40,000 prosthetic technicians in the developing world.

The process is too long

  • It takes a 6 day, multi-step process to create one custom-fit prosthesis.

OUR SOLUTION


Rosalyn

A prosthetic socket scanned and printed using digital technology.

A prosthetic socket joins a residual limb to the prosthesis. It's the piece that's "made to fit" each child - ensuring comfort and usability. It's also the most time consuming part of creating a prosthesis.

In the traditional process, crafting a custom-made socket takes a week of casting, reating a mold, and, finally, fashioning the socket. By 3D printing the prosthetic socket - we hope to create a higher quality product at a fraction of the time and cost of traditional methods.

Our estimates show this new process could lower the cost from $5000 - to $250 per prosthesis, reducing the time to create a prosthesis from 6 days, to 6 hours.

HOW 3D PRINTING GAVE ROSALYN A NEW LEG


Scan

STEP 1: SCAN

Working with a crew from the University of Toronto - CoRSU staff scanned Rosalyn's residual limb, creating a digital copy of her remaining leg.

STEP 2: EDIT

Using software developed with Autodesk Research in Toronto, the technician inverted the digital scan of Rosalyn's residual leg, using 3D modelling to create the prosthetic socket.

STEP 3: PRINT

The model of the socket was sent to a 3D printer. Plastic filament was melted and extruded through a nozzle (think of a fancy inkjet printer). Layer by layer, a sturdy socket was created - made to fit Rosalyn's leg.

STEP 4: FIT

A liner was placed inside the socket - making it comfortable to wear. The newly created leg was fitted to Rosalyn - and she took her first steps.
