The Single Axis Prosthetic Foot is expected to assist the activities of people with disabilities. A prosthetic foot can greatly aid in the daily activities of individuals with disabilities due to amputation resulting from accidents or illnesses such as diabetes. According to data from the Ministry of Health in 2017, 88% of Indonesia's total healthcare needs are still imported, including prosthetic feet.

This inspired the Master of Biomedical Engineering student, Devi Dwi Rahmatika, to research this topic with the thesis title "Fabrication of Single-Axis Prosthetic Foot Using 3D Printing and Resin Infusion Method".

Devi found that the prototype of the single-axis prosthetic foot could be proposed as an alternative assistive device for disabled patients to carry out daily activities. It can support the user's weight up to a loading between P3 or 60 kg and P5 or 100 kg, providing comfort and safety before fabrication.

The fabrication of this prototype used Fusion 360 software, followed by simulation testing using ABAQUS 6.14 software. The prototype model was designed and analysed to obtain strength and feasibility before fabrication using a DLP 3D printing machine type Anycubic Photon Mono X with resin infusion method.

The mass or density of the single-axis prototype is 657 grams, meeting the criteria of not exceeding 1.7 times the total weight of the user, with a hardness value of 55.5 HA and capable of enduring 50,000 cycles in fatigue testing.

With guidance from Dr. Ir. Budi Arifvianto, S.T., M.Biotech, and Ir. Rini Dharmasiti, M.Sc., Ph.D. IPM., ASEAN Eng from the Faculty of Engineering, along with examiners Dr. Urip Agus Salim S.T., M.EngSc also from the Faculty of Engineering, and Dr. Zikrina Abyanti Lanodiyo, Sp.OT from FKKMK, Devi graduated on April 24, 2024, with cum laude honours. This research also aligns with SDGs number 4 Quality Education concerning Disability.
