Ukrainian engineers develop 3D-printed airless wheels for frontline robots

Unmanned ground vehicles operating on the front lines in Ukraine are receiving a critical mobility upgrade following successful combat trials of new airless wheels. Developed through a collaboration between Print&Live UA, iSCALE 3D, and participating specialists, the inflation-free wheels are built using large-scale 3D printing technology to keep robotic platforms moving despite severe battlefield damage.

Traditional pneumatic tyres frequently fail after encountering shrapnel, explosive blasts, rubble, barbed wire, or frozen terrain, leaving remotely operated vehicles immobilized and vulnerable. The newly engineered design eliminates internal air pressure dependencies, allowing the wheels to maintain structural support without routine maintenance or the risk of punctures. Each complete wheel set weighs between 32 and 56 kg, offering a significantly lighter alternative to existing foreign airless models that can weigh up to 144 kg.

The internal architecture relies on a digitally adaptable lattice constructed from durable elastomers and composite polymers. Featuring a closed profile and a rounded tread geometry, the tyres are specifically shaped to minimize the accumulation of dirt, stones, and ice. Developers estimate that this low-mass configuration can extend the operating distance of ground robotic vehicles by up to 30 percent compared to certain foreign alternatives, while simultaneously reducing mechanical strain on electric drive systems and gearboxes.

Manufacturing flexibility stands as another core advantage of the project. Engineers can digitally adjust wheel stiffness, shock absorption, and geometry to match the specific weight and operational demands of different robotic platforms without overhauling production lines. Furthermore, a patented two-piece rim enables straightforward field repairs, allowing damaged tyres to be swapped out without relying on heavy specialized machinery or traditional workshop equipment.

With the research and development phase now concluded, production is currently underway in limited quantities to supply active combat units. While initial field evaluations are promising, ongoing operational deployment will provide definitive evidence of how the 3D-printed wheels hold up under sustained impacts and extreme environments.
