GEN 12: please see my profile for the GEN 12 ball. There&#39;s a limit of 500mb on one page so I had to make another for the latest Gen. It bounces really well and feels super durable in TPC I wasn&#39;t satisfied with the current models of the airless basketball on here as they only had a single lattice. This took me days make sure the double lattice worked in CAD - SolidWorks was not built for this! As I don&#39;t have $2,500 to spare, I worked from the images available online.I printed it in TPU. It doesn&#39;t bounce as much as a standard basketball in TPU so I suggest a stiffer material.&nbsp;GEN 9: I have added a gen 9 version. It is a little closer to the original and should weigh about the right amount when printed in TPU/PLA&nbsp;GEN 10: I have adjusted the size of the hex holes and increased the filled on them. I&#39;ve also increased the lattice thickness to 8mm to hopefully increase bounce. The logo on the top and the airless gen 10 tag have also increased in size a little to improve how they look. Lastly, the holes around the seam are now pentagons as in the original ball&nbsp;GEN 11: I have added a new version with cut-outs throughout the seams. This will hopefully make the bounce more consistent.&nbsp;The original version I uploaded was removed due to “abnormal download data”. MakerWorld support took all my points but said I could re-upload so here it is again. Hopefully that won&#39;t happen again. MATERIALS:Extrudr Hard TPU (58D) - good durability about 40% bounceOverture Super PLA+ - 100% bounce but broke easilyOverture easy nylon (PA6) - broke almost instantly (the community have suggested “annealing” the print in water to increase durability)BASF Forward AM Ultrafuse TPU 64D - good durability and 60% bounce (BEST SO FAR)BASF Ultrafuse TPC 45D - good durability and great bounce. I recommend annealing this one at 110°C for 10 hours at least.

Airless Tennis Ball 2.0, a complete redesign based on feedback received from more than 10,000 downloads of the previous model.&nbsp;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.&nbsp;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.&nbsp;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.&nbsp;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.&nbsp;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.&nbsp;Check my current state on airless balls:Airless Ping Pong, Table Tennis Ball: <a target="_blank" href="https://makerworld.com/en/models/386079#profileId-286461" rel="nofollow noopener">https://makerworld.com/en/models/386079#profileId-286461</a>Airless Baseball Wiffle Softball Ball v2.0: <a target="_blank" href="https://makerworld.com/en/models/227359#profileId-244997" rel="nofollow noopener">https://makerworld.com/en/models/227359#profileId-244997</a>Airless Basket , Soccer, Voley or Handball Ball v1.2: <a target="_blank" href="https://makerworld.com/en/models/223189#profileId-241192" rel="nofollow noopener">https://makerworld.com/en/models/223189#profileId-241192</a>Airless Golf Ball: <a target="_blank" href="https://makerworld.com/en/models/383904#profileId-284030" rel="nofollow noopener">https://makerworld.com/en/models/383904#profileId-284030</a>&nbsp;
