Brake pedal
· Client : YUSAE (Yeungnam University Society of Automotive Engineers)
· Role :
Supported the production of a brake pedal prototype
with DfAM design for the competition.
Harvestance was exploring 3D printing cases for mobility
with YUSAE and decided to try to make a brake pedal.
[First Brake Pedal Model Shape]
Material : Steel, weight: 330g
Previously, the brake pedal was manufactured
by laser cutting the steel plate and welding 7 parts.
Produced high-intensity, high-performance brake pedal
by utilizing the freedom of shape, which is the advantage of 3D printing and composite materials.
Material | Steel → Carbon Fiber Composite material |
Method | Laser cutting & Welding → 3D Printing |
Used Onyx as the base material and
optionally reinforced carbon fiber where additional stiffness is required.
Onyx is a material consisting of plastic nylon and carbon monofiber,
If you reinforce carbon long-fiber,
It will have a stiffness equivalent to Al6061
When using 3D printing,
along with changing materials and processing methods,
the most important element of the design optimization process has increased the efficiency of the parts.
· To create optimal design, Harvestance utilized Generative Design, which has recently become a hot topic in the design industry.
It is useful for creating structurally optimized, consolidated designs based on processing methods, materials, boundary conditions. |
Initial Model
Final Model
The optimal printing direction is determined by considering the location of the geometry that requires stiffness,
and the area where the support will be generated is also considered.
For 3D printing of composite materials,
The printing process is also an important part.
The direction of printing changes the area where the carbon fiber can be reinforced.
Markforged's 3D printer used in this application can easily remove support structures by hand,
and has fewer scratches on the surface, making post-processing very convenient.
