The 3D printing manufacturing process has the possibilities to produce individual medical devices, especially implants and prosthesis with short production time. The criteria of the prosthesis were 3D printable, low cost, simply geometry and satisfying mechanical properties for low activity use. Most of the prosthetic feet are designed with more weight and material than required. The topology-optimized model is printed from a Three-dimensional (3D) printer directly rather than interpreting the model using a Computer-aided design (CAD) software. Prosthetic limbs play a vital role in restoring mobility and enhancing the quality of life for individuals with lower limb disabilities. With the advancement of additive manufacturing technologies, 3D printing has emerged as a promising technique for the design and fabrication of personalized prosthetic devices. This abstract presents the manufacturing and testing process of a 3D printed prosthetic foot, highlighting the benefits and challenges associated with this innovative approach. The manufacturing process begins with the acquisition of a 3D scan of the patient's residual limb. This scan is used to create a digital model, which is further refined using computer-aided design (CAD) software to ensure a precise fit and functional design. The foot's geometry is optimized to provide stability, shock absorption, and efficient energy return during walking and running.
