New legs for disabled people

1. PROJECT TOPIC : PROSTHESTIC
LEGS
By Nsemel Seidou Said

2. PROBLEM STATEMENT
One of the greatest challenges we face today is
physical disability. A physically disabled person is
one who suffers from the loss of impairment of a
limp or deformity due to an unexpected
unfortunate accident.

3. OBJECTIVE OF PROSTHESTIC LEGS
Prothestic legs can help people with leg amputations get around more
easily. They mimic the function and, sometimes, even the appearance
of a real leg. In other words it helps in daily activities such as walking,
dressing, or running.

4. Prosthetic Materials
A wide variety of materials are used to create the
actual limb, including acrylic resin, carbon fiber,
thermoplastics, silicone, aluminium, and titanium.

5. What material is 3D prosthetics ?
Materials used in 3D printed prosthetics are those that are durable and lightweight
such as plastics( Acrylonitrile butadiene styrene (ABS) or for a stronger material,
Bridge nylon. As an added benefit, the internal structure comprises lightweight
materials such as titanium, aluminium or carbon fiber.

6. What are the benefits of 3D printed
prosthetics ?
The main benefit is the cost and time efficiency that the
process offers as well as the wide availability of the material.
That is a 3D printed prosthetic leg can cost $ 395, which is
equal to 241226.5 FCFA and can be produced in one day,
depending on the technology used in the manufacturing
process.

7. THE PROTHESTIC PROCESS
 Step 1 - Measurements
To ensure proper fit, a practitioner will measure your residual limb. Our team uses plasters
or fiber glass to complete this intimate measurement.
Step 2 - Individual Needs and Goals
Communicating and working together, our practitioner and patient will discuss the patient’s
wants, needs and goals to ensure the prosthetic leg will support their lifestyle.

8.  Step 3 - Casting and Check Socket
The practitioner will cast the residual
limb of the patient, and use this molding
to create a diagnostic socket. This socket
is transparent and allows our team to
review the fit and make adjustments.
This process occurs to ensure optimal fit.
 Step 4 - Assembly of Prosthetic
The practitioner and technician work
together to fabricate the prosthetic leg
correctly. This may require ordering
parts from outside manufacturing
companies.

10. What design and manufacturing processes are useful for
prosthetics?
 Advanced manufacturing (AM)
techniques, including three-
dimensional (3D) scanning,
computer-aided design (CAD), and
computer-aided manufacturing
(CAM), can be collectively used to
reduce the time, labour, and cost of
prosthesis fabrication
