Ukraine’s 3D-printed airless wheels weigh 32–56 kg per set

Ukrainian engineers have developed airless wheels for unmanned ground vehicles, with limited production underway for combat units, according to TechRadar, citing Militarnyi.

The project brings together Print&Live UA and iSCALE 3D. The wheels use large-scale 3D printing and have a rounded tread, enclosed profile and two-piece disc. Their structure includes a digitally adaptable lattice made from elastomers and composite polymers. Without internal air pressure, the wheels do not need inflation or routine pressure maintenance.

Print&Live estimates that the design could extend a ground robot’s operating distance by as much as 30% compared with foreign alternatives. A complete set weighs 32–56 kg, versus 88–144 kg for the foreign airless alternatives cited in the report. Conventional pneumatic sets weigh about 30–72 kg, so the Ukrainian wheels are not necessarily lighter than every traditional option.

The developers say the design can be adjusted digitally for stiffness, shock absorption and geometry to suit a robot’s weight and operating needs. The patented two-piece rim is intended to let users install or replace damaged tyres without conventional tyre-changing machinery. A complete set reportedly costs about €680; the report does not specify the configuration or replacement costs included.

The project has completed research and development, and production is underway in limited quantities for delivery to combat units. Independent operational evidence is still needed to establish performance during sustained use and under varying conditions.
