Super Bounce Ball

It bounces TWO STORIES!

Recommended Filament: eSun eflex TPU 87a.

Can be purchased at Microcenter under the name:  Inland Elastic TPU (Natural) 0.5KG

Humans typically bounce basketballs at 10-20 newtons of force. TPU 87a's tensile strength of 52 MPa along with its 500% Elongation at Break make it the perfect candidate for this ball. It just misses the yield strength of the material making it have ‘maximum bounce potential.’ 

Maximum Principle Stress of ‘Super Bounce Ball’ in TPU 87a

This 3D-printed ball features a finely tuned honeycomb lattice structure that is not just visually appealing but also engineered for optimal bounce dynamics. The geometry evenly distributes forces across its surface, giving it a near-perfect rebound when dropped or thrown. Its light yet robust structure allows it to compress and expand efficiently, resulting in a smooth and consistent bounce.

Designed with precision, the lattice structure minimizes deformation while maintaining durability. Printed with a 0.8mm nozzle, this ball strikes the perfect balance between print speed and structural integrity. A 0.4mm nozzle is also a viable option for finer detail, but a 0.6mm nozzle is not recommended as the layer math does not divide evenly, potentially compromising the print quality and bounce performance.

Key features:

• Engineered honeycomb geometry for optimal bounce and force distribution.
• Lightweight and durable structure, ideal for dynamic testing or play.
• Recommended nozzle size: 0.8mm (preferred) or 0.4mm for finer detail.
• Not suitable for 0.6mm nozzles due to layer division issues.

This ball isn’t just a print—it's a demonstration of the interplay between design and physics, ensuring a fun and functional result straight off your printer!
