CAD helping lives

CAD and CAM is not just about engineering or manufacturing, it is a necessity in our daily lives. The car that we travel in to go to work everyday, ships and aeroplanes that allows us to cross oceans and travel across the globe, our phones, computers, machines that makes us coffee, toasts, all these are at one point designed with CAD, and manufactured with CAM.

Therefore, CAD and CAM is really not as hard to understand or far from us afterall. With the aid of CAD/CAM, the products that we are using daily are safer and more reliable. Below is a story that I like about how Engineering and CAD is helping lives (a duck in this case):

Dudley the Duck with its New 3D Printed Foot
Dudley the duck is a lucky fella to be able to walk again after losing one of its foot in an unfortunate encounter with a chicken. It's prosthetic foot was designed in SolidWorks and printed with 3D printer. There are a lot of factors taken into consideration in designing a feasible and sustainable foot that is not only nice to see but also practical for a duck:
Requirement: Fully support Dudley’s weight
Solution: Main structural components (upper-leg, lower-leg, connecting pin for joints) will be composed out of a stronger ABS-type plastic final leg will be a medical grade plastic).
Requirement: Multi-jointed to allow for a smoother gate
The ankle joint allows for approximately 20 degrees of rotation while the knee joint allows has a curved flexible knee piece connecting the upper leg and lower leg which isolates the rotation of the knee while still acting like a shock-damper.
Requirement: Lightweight to reduce Dudley’s energy consumption.
We are testing several lightweight plastics out to see if it is both light and strong enough for our application.
Requirement: Realistic foot to allow for more effective swimming

Isn't it great to see engineering surrounding us everywhere? Although I am not part of those who makes a difference in a duck's life (pun intended), I am proud to call myself an engineer and be part of the SolidWorks community who is giving back to the society. 

Happy Weekend to you :)
