This pet mobility aid meets rising demand in a pet care market growing 7–9% annually. Existing devices are often bulky and lack comfort. Using 3D scanning and local multi-material printing, this design offers a lightweight, modular fit tailored to each dog. Tested dogs showed restored mobility and reduced stress for owners. The quick-swap system improves daily use across varied settings. Made from recyclable TPU and produced locally, it reduces waste and supports sustainable, scalable production.
