Materials Subteam Progress
Milestones
Timeline
Read about our progress milestones starting in September of 2024 and what we have planned for the future.
Winter-Spring:
January - March 2025
We conducted extensive literature reviews and analyzed manufacturer data to determine which materials would best meet the functional demands of our prosthetic design. Our research supports the design and manufacturing teams by ensuring that every material chosen is backed by technical evidence and aligned with our goals of affordability and scalability.​​
​
Progress:
-
Analyzed 12+ academic studies on 3D-printed prosthetics and material performance.
-
Compared key mechanical properties (tensile strength, impact resistance, elasticity, hardness) across multiple material types and manufacturers.
-
Evaluated adhesive options for bonding flexible and rigid materials, Velcro, and mesh components.
-
Investigated practical factors like medical safety, cost, ease of access, and printability.
​​
Final Material Recommendations:
PETG (Rigid Socket)
Chosen for its balance of strength, flexibility, and printability. It can withstand everyday stress from walking and provides the structural support the socket needs.
​
TPU (Flexible Straps)
A durable, stretchy material that adapts to movement and growth. Ideal for the adjustable straps that keep the prosthetic secure and comfortable.
Medical Foam & Mesh
Used to line the inside of the socket, these materials provide cushioning, breathability, and comfort against the skin.
​​
3M™ DP8010 Adhesive
A strong, specialized glue that bonds components like Velcro, mesh, and 3D-printed parts together. Selected for its durability and reliability.
