About Three Minute Thesis

Winner of the 2025 UTS 3MT Finals

Ahmed Da’na from the School of Design in the Faculty of Design and Society took out the top honour with his presentation, ‘From scan to step: Custom knee-ankle-foot-orthoses (KAFOs) for polio survivors’. He earned $3000 in prize money as well as a place at the 2025 Asia-Pacific 3MT competition representing UTS.

Ahmed’s work combines human-centred design, 3D scanning, finite-element-analysis and sustainable manufacturing to deliver personalised, efficient and eco-conscious devices.

UTS 3MT Winner 2025: Ahmed Da'na transcript

Hello.

Five steps.

How many of you counted each step I took? How many of you envied each step I took? Many of us don't think about this. Walking, one of the most common forms of movements is the start of mankind. something that many of us take for granted. Hundreds of millions worldwide struggle with this. One of the oldest neurological reasons for this is polio. It causes weak muscles and paralysis in the legs.

My name is Ahmed. I'm an industrial designer and researcher working with an orthotic clinic in Sydney. Polio. Isn't that so last century? You may be surprised to know that there are over 25 million worldwide who have it. 500,000 here in Australia to assist with walking and knee ankle foot orthosis is used. These are very complex mechanical devices. However, doctors have figured this out centuries ago, haven't they?

Today we still use very primitive and labor intensive methods that are expensive and super wasteful. In the eyes of the patients, it's widely documented that this process is uncomfortable and many don't wear it due to its overpowering and industrial look. Typically, these can take up to two months to deliver, which is far too long.

Fortunately, the orthotic clinic and I have used an innovative method called fused pellet modeling. It's a fast 3D printing process that's great for large and durable products. Instead of two months, two weeks alongside this, a testing framework where any new device or material can get tested, hoping to influence new TGA regulations.

The patient walks into the clinic, gets a 3D scan of their limb, then can decide what colors or features they would like. This is crucial. They can now have a meaningful and custom device that suits their own lifestyle.

Once the orthosis has done its job, it gets sent back to us. We can slice it up and shred it, throw those granulates back into a printer and reprint another orthosis now for a new patient, creating a sustainable and closed loop. Polio, cerebral palsy, multiple scerosis, and the rise of trauma events can definitely benefit from this new digital workflow. 25 steps. It's 2025. Let's help make each step feel steady, strong, and comfortable.

Three Minute Thesis: Founded by the University of Queensland.

First held at the University of Queensland in 2008, the Three Minute Thesis (3MT) has grown in popularity and become a highly anticipated event for research students. Competitions are now held in over 900 universities across more than 85 countries worldwide.
