3D-Printed Airless Tires – iSCALE3D
Summary: Standard pneumatic tires account for roughly 90% of operational failures in Unmanned Ground Vehicles (UGVs). By replacing pressurized air chambers with dynamic digital lattice geometry, iSCALE3D's fully 3D-printed airless tires eliminate punctures while preserving vehicle mobility in mud, snow, and rocky terrain.
Key Takeaways
- Zero Pressure Chamber: Punctures are physically impossible; the tire relies on internal digital lattice structures rather than compressed air to absorb impacts and support heavy loads.
- World-First Closed Side Profile: A fully sealed side design prevents mud, rocks, and debris from clogging the lattice structure, preserving vehicle energy efficiency and operational range.
- Field-Tested Reliability: Proven in harsh real-world conditions across multi-hundred-kilometer deployments, operating flawlessly in extreme temperature ranges from -30 °C to +40 °C.
Detailed Overview
In high-risk logistics, agricultural field operations, and defense missions, pneumatic tires are a critical single point of failure. Shrapnel, sharp rocks, barbed wire, and rebar can easily puncture conventional tires, immobilizing vehicles and failing missions.
iSCALE3D solves this challenge by manufacturing fully airless tires printed layer-by-layer from durable elastomers and composite polymers. By combining the tread and damping structures into a single continuous print, these wheels maintain structural integrity even after taking severe physical damage.

Deep Dive & Technical Insights
1. Digitally Programmed Damping Structure
Because the wheel is built via large-format additive manufacturing, structural stiffness and damping properties can be digitally tailored to match specific UGV platforms and payload requirements. Tread patterns and load-bearing internal lattices emerge as one single piece without requiring vulcanization, chemical bonding, or mechanical assembly.
2. Closed Side Profile Technology
Existing open-spoke airless tire designs regularly fail in off-road environments because dirt, stones, and heavy mud gather inside the open lattice, significantly increasing wheel weight and reducing vehicle range.
iSCALE3D addresses this with a closed side profile. The sealed outer shell blocks foreign materials from entering the wheel core, keeping vehicle mass and energy consumption steady throughout long operations in deep mud or packed snow.
3. Field-Serviceable Two-Part Rim
Airless tires require uniform clamping forces across the entire wheel circumference to transfer torque effectively. iSCALE3D engineered a custom two-part rim weighing 8 kg using carbon-fiber-reinforced nylon components and a bolted flange ring.
Because the rim features a split-halves construction, operators can replace damaged treads directly in the field using basic hand tools without specialized hydraulic presses.
Field Testing & Performance Benchmarks
The 3D-printed airless tire system has been subjected to rigorous stress tests on Ukrainian field UGV platforms across multiple seasons and terrain types.
| Benchmark / Testing Parameter | TARGAN 3K 244 EVO UGV | "Rys Pro" Evacuation UGV |
|---|---|---|
| Total Distance Tested | 361 km (including 151 km frontline operation) | 285 km |
| Payload Handled | 1,825 kg cargo delivered across 11 missions | ~800 kg (Double the rated 400 kg limit) |
| Operational Terrain | Frozen, rutted ground (0 °C to -15 °C) | Deep swamp terrain & vehicle recovery towing |
| Test Result | Local surface wear; 100% operational completion | Tread wear under double load; zero delamination or cracking |
Decentralized Localized Production
Traditional pneumatic tires rely on long global supply chains, centralized rubber processing facilities, and extensive warehousing. By contrast, additive airless tires turn production into a digital workflow.
Developed in collaboration with Lemki Robotix and Zeykan Robotics, replacement tires can be printed on-demand near the point of use using digital files and localized raw materials, bypassing traditional supply chain delays.
Conclusion & Resources
iSCALE3D’s airless tires eliminate tire flat risks for unmanned ground vehicles operating in extreme environments. By pairing a debris-rejecting closed side profile with a field-serviceable two-part rim, this additive manufacturing approach provides reliable mobility for defense, evacuation, and agricultural platforms.
- Puncture Proof: Eliminates compressed air chambers to achieve complete immunity against flats.
- Debris Protection: Closed side walls prevent mud and stone buildup to preserve energy efficiency.
- On-Demand Readiness: Enables local additive production of custom wheels tailored to specific vehicle loads.
