Considering we spend so much time striving for strength and rigidity in our 3D prints, it's a relief to create with flexible filaments! Using a standard FDM printer and TPU filament, I created scaled down versions of Airless Tires. Non-pneumatic or Airless Tires are already emerging in commercial, industrial, and military applications. However, I think it'll be a while before we see them at your local dealership!

4" Tire. Print the tire in FPLA or TPU, and the core hub with any rigid material. Fit's standard 12mm nut and 1:10 RC cars

Happy Printing!
