The need for prosthetic limbs is too great.
The resources are too few
The process is too long
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
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.
