Imagine a fascinating airless tennis ball printed entirely from filament, built around a flexible honeycomb or hex-mesh shell that bounces almost like the real deal—no inflation needed, no punctures, no leaks. Many printable versions like Airless Tennis Ball V2 and the well-tested v1.1 or GEN 2 models rely on that open structured lattice geometry to absorb and release energy. TPU 95 A or TPU 98 A (or PLA-Flex) are recommended for maximum bounce and impact resistance, with TPU-98 A models achieving around 50 % of standard drop-bounce height, while TPU-95 A gives slightly less but resists cracks better—PLA/PLA-Plus prints can work as display models but are brittle for play. Recommended print settings for durability are around 0.16–0.20 mm layer height, minimal infill, usually about 2 walls or shells, and supports only under the base to avoid obstructing the interior mesh.
