Airless Tennis Ball 2.0 , a complete redesign based on feedback received from more than 10,000 downloads of the previous model.

Updates:

Improved hex mesh density to add strength and functionality in a wider range of materials. General increase in thickness for a better feeling of weight and bounce. Polished seam line to achieve homogeneous bounce capacity throughout the entire ball and better aesthetic approximation.

The conclusions on recommended materials show that to achieve impact resistance it must be printed on flexible materials with a certain level of hardness to keep bounciness.

Recommended materials for bounciness aproach are TPU 98A and PLA Flex (as seen in gif from 3DJVModels, check his profile!). They are materials similar in their hardness, which provide a bounce distance of +-50% from the drop height, while the official bounce is 53-58%.

TPU 95A resists impacts without breaking but has a bounce reduced to approximately 20% from drop height.

Among flexible materials, TPU in its different hardness provides an incredible level of layer adhesion, which is why it achieves the highest tested impact resistance without cracks.

PLA or PLA+ will work only for displaying purposes. We do not recommend using these materials if you want to make it bounce as it can break easily.

Профили печати и шаги

0.2mm layer, 2 walls, 25% infill TPU profile, reduced speed for better base finish and easier support removal.

0.2mm layer, 2 walls, 25% infill TPU regular profile, reduced printing time.

0.2mm layer, 2 walls, 25% infill PLA and PLA+ profile only for displaying purposes. Do not try to bounce it as it is likely to break.

FPLA - 0.16mm layer, 2 walls, 25% infill This Print Profile is specifically for Ataraxia Art's FPLA at a 0.16mm layer height but feel free to use it for other FPLA types. Bounces nearly the same as a real tennis ball! Printed at a lower layer height for detail but there should be no issues if you would like to change to 0.2mm. You also should leave the door open if printing on a P1S or X1/X1C to allow for proper cooling on overhangs.

Side note, I found the textured pei plate to be best for removal of this type of filament but be sure to use a releasing agent such as a glue stick!

0.2mm layer, 2 walls, 10% infill Geringere Schichtdicke, daher nicht so hart und springt schön. Optimal für Speedminton!

Wisdream Flexitough - 0.6mm nozzle For Wisdream Flexitough fliament - use a 0.6mm nozzle. Add magnets on top of the flat cylinder as soon as you can to help adhesion. When done printing, turn the plate temp up to 80C, wait a bit, then pull supports right off. This is the best way to reduce support cleanup, but a bit of sanding and use of cutters will still help.

PEBA, 0.6mm nozzle, 0.3mm layer, 2 walls, 5% infill PEBA bounces better than any TPU filament i have tried and this is the perfect print profile for it.
