Pet Prosthetics: Bringing New Hope and New Life

Over the preceding decade, veterinary orthotics have begun to evolve rapidly. What was previously categorized as a niche and specialized field has transformed into a dynamic frontier of animal biotechnology, catalyzed by 3D printing, digital scanning and bespoke fabrication protocols. Today, companion animals throughout the nation, and even right here in Ohio, are reaping the restorative benefits of prostheses that are demonstrably lighter, more comfortable, and more precisely fitted than ever before!

Historically, orthopedic appliances for companion animals relied on cumbersome media such as forged metal, heavy leather, and inflexible plastics. However, these compounds are notorious for excessive weight and all the discomforts that come with them. Consequently, numerous patients encountered insurmountable barriers to adaptation, requiring continuous recalibration or just abandonment of the devices altogether. Contemporary additive manufacturing has fundamentally revolutionized this paradigm. Pioneers like 3DPets harness have changed this landscape. Their workflow begins with either an in-office 3D scan or a mold created at home using DIY methods. The scan is used to design a custom harness and limb, which is then printed and fitted to the pet. The result is a lightweight, breathable, flexible device that matches the pet’s unique shape and mobility needs.

This approach solves one of the biggest historical problems in pet mobility, which is poor fit. Generic wheels and rigid braces long failed because nature never made an average creature; she made only individuals. By honoring this truth through custom crafting, they achieve over 98% perfection, wrapping broken bodies in comfort and giving the earth back to those who thought they could no longer walk upon it.

The prosthetics revolution is not limited to dogs. 3DPets and similar innovators have expanded their work to include pigs, goats, tortoises, alpacas, llamas, and even elephants, demonstrating how adaptable 3D-printed solutions can be across species. One notable example here is ODot, an East African grey crowned crane at the Columbus Zoo and Aquarium. After an old fracture left her unable to use her left wing normally, she repeatedly struck and reopened an abrasion near her wrist. In 2023, zoo staff and an engineer developed a custom 3D-printed plastic “wing cap” prosthesis that wrapped around and protected the injured area. Following adjustments, it stayed in place, allowed the wound to heal, and helped ODot return to the zoo’s Heart of Africa savanna with other cranes.

As scanning technologies become more accessible, even through smartphones, and 3D printers continue to advance, custom prosthetics will likely become more affordable and widespread. Academic engineering faculties and veterinary institutions throughout Ohio are exceptionally situated to accelerate this trajectory, propelled by expanding interdisciplinary collaboration. Spanning from national pioneers such as 3DPets to engineering students designing prosthetics for cherished companions, the field is accelerating rapidly toward a horizon where physical trauma or physiological disability no longer prevents an animal from living their best lives.
