Honda Tochigi Racing to test recycled 3D-printed parts from automotive waste at 2026 Suzuka 8 Hours

Honda Tochigi Racing, a motorcycle club composed of Honda Motor Co. employees from its Tochigi region, will field recycled 3D-printed components on its race bike at the 2026 Suzuka 8 Hours endurance race, held July 3-5. The parts - number plates for the front and rear of the machine - are made from resin waste recovered from scrapped vehicle headlamps. Nagoya Kogei, a Japanese 3D printing service bureau and Prusa Research distributor, handled material reprocessing and fabrication using a Prusa Pro HT90 industrial FDM/FFF printer. The company operates a farm of over 100 3D printers under its "MIRROR FARM" brand, offering material development and production services from prototyping to series runs.

This application sits at the intersection of two underappreciated AM frontiers: automotive circularity and motorsports validation. While polymer AM has long been used for jigs, fixtures, and prototype trim on race cars, using recycled automotive waste - specifically headlamp resin - in a production-grade endurance racing component is rare. The Suzuka 8 Hours subjects parts to sustained high-speed vibration, heat, and aerodynamic loads at speeds exceeding 300 km/h. Success here would provide a credible durability reference for recycled FDM materials, which have historically struggled to escape the desktop prototyping ghetto. For the broader AM industry, this is a materials qualification discipline story: the bottleneck is not printer capability but the qualification of non-virgin feedstocks for functional use. Nagoya Kogei’s vertical integration - from waste collection to filament extrusion to print - mirrors the supply-chain localization pattern seen in metal AM, but applied to polymer circularity.

From an analyst perspective, this is a small but structurally sound proof point. The part is a number plate, not a safety-critical structural component, which keeps the risk profile appropriate for a first test. The real signal is that Honda’s internal racing team chose to invest engineering time in validating recycled feedstock rather than using virgin material. For Nagoya Kogei, the next step is converting race-weekend data into a repeatable material specification that other automotive or industrial customers can adopt. The Prusa Pro HT90 is a capable machine, but the value here is in the material chain, not the hardware.
