Description

I wasn'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't have $2,500 to spare, I worked from the images available online.

I printed this in BASF TPC and then annealed it for 3 hours at 100°C. It is the closest I've seen to the original in bounce and durability. It's about 90% bounce and seems to be holding up to a lot of abuse. It cracked along the layer lines after a few days so I'd reccomend annealing it for a lot longer than 3 hours.

I've had to upload GEN 12 as a separate page because there is a limit on the combined size of files on here.

The changes in this version are: adjusted the thickness of the hex lattice to make sure the weight is about right. It should be 605g if printed in TPC which is pretty close to the NBA ball. As you can see from the video, it bounces really well.

just printed it in TPC, 100c bed temp and 240 nozzle, 15cm tall ball printed in 22 hours, supports peeled off super easy no problem. the ball is AWESOME! it bounces really well. I tried to size it for my indoor mini hoop and it works perfectly and I could even say it bounces slightly better than the cheap balls the hoop comes with. I’ve heard rumours of people trying PEBA soon so I will wait for those results before trying a full size ball, but very happy with these results so far thank you!

@rotnam

Which brand / TPC you got ? Im having a bad time finding anything

@user_1331369075

Replying to @rotnam :

i purchased “BASF 1.75mm Silver TPC 45D”, it’s roughly between £40-80 for 1kg, and the 15cm ball used about 240g. I am in the UK so I am not sure about other country availability

What I can see here from the picture is that you got a lot of stringing, did you dry the filament before use or is this filament that stringy?

@user_2056401815

i try printing it with Dupont hytrel tpc 60d shore

@PartyLime

How does it bounce?

@user_2056401815

bounce more than tpu but less than pla but it seem indestructible, i thinks peba must work well

@user_2056401815

nice filament bridging are awesome

@jonjon84

Thank you. The model worked great with Fillamentum Flexfill PEBA 90A. Bounce is great. I scaled it to about 78 % and Printed it on my p1s

@user_2056401815

hi Can u share a vidéo of bounce with peba

@mpawood

Replying to @user_2056401815 :

There's a video about PEBA here: https://youtu.be/fFt1uC8Evgs it seems to have 99% the bounce of a regular basketball. I think it's the closest you'll get with a normal FDM printer. Shame it's £100/KG

@user_3917682497

Do you think that this print would work on Ender 3 Max Neo or ELEGOO Neptune 3 plus/3 max/4plus with Kimya TPC 91a filament? I think with 100c bed temp and 240-260c nozzle temp should work. I am concerned that while printing the overhangs, the single cooling fan won't cool it down fast enough.

@PartyLime

You can ad a desk fan to help with the cooling. I think it should work with that setup

@user_3917682497

Replying to @PartyLime :

Filament just arrived, and it says recommended bed temp of 80c, so should I follow that, or go ahead with 100c bed temp?

@user_3917682497

How long did it take to print? while slicing the file, it says it would take 13 days to print.

@user_4162728368

Printed in flashforge flexible. Bounces well, about 70% but one panel cracked after a few days. Pretty sure it's my fault. I tried squishing it excessively and felt the inner lattice break from stretching too far.

@bryceschutte

Mine did the exact same thing. There is a weak spot.

@user_4162728368

Replying to @bryceschutte :

On other sites like printables there's the "airless max." Only other double lattice design i've seen. I printed that one too but PartyLime's design is my favorite. However some of the features on the other one make it stronger. Some of those features worked into this one would be perfect.

very difficult print with Ataraxia Flex PLA but finally succeeded 😅

@.s_.

im printing it now with the same thing how was support removal. I never shoulda subscribed to thus stuff from amazon I have 5 more rolls of it LOL

@mettleh3d

it was difficult to remove but doable. yeah, I don't know what to do with the remaining stuff it's a chore to use lol

@bojan_perko

Wonderful design, thank you for sharing your work. I've already ordered the recommended BASF TPC 45D to print it and I am afraid of failure because of length of print and price of filament so I have some questions: what printing plate did you use and did you apply glue? Did you print the supports with the same filament and how difficult were they to remove? Do the temperatures and speeds in the uploaded print profile require any modifications or are they good to go? I've got the P1S without AMS.

The designer has replied

@PartyLime

I used some bed glue I picked up at SMRRF - I think it was called InstaGoo. I then had the bed at 100°C. This was on the textured PEI sheet. The supports still warped a little bit but it didn't affect the actual ball. I don't know how much the InstaGoo actually helped, I think the 100°C bed was the main help. Yes, I printed the supports with the same material as I think it's too soft for the AMS. They were fairly difficult to remove - I think it took about 30 mins with a pair of pliers and side-cutters. I used the recommended settings from BASF for the filament (except the bed temp which I upped to 100°C). I also printed with the door closed and lid on. I think other than that, the print profile here should work.

Thank you so much for your reply. I'll proceed as you recommend. All the best!

Replying to @PartyLime :

Awesome design 👍!! I am going to print this soon too with your mentioned TPC, but wouldn't it be much easier to print the 2 halves separate and thus avoid supports and afterwards just glue them together?

Absolutely incredible model. I can’t express how impressed I am that this was modeled in SolidWorks. I love the detail and intricacy. I’ve printed several in different materials, and I love the ones I’ve done in TPU. This time I modified the print profile ever so slightly to use nylon. I can confirm that Gizmodorks PA does NOT work. Didn’t even bounce once. probably should have soaked it for a day to give it more flex, or maybe annealed it. Ah well. Hindsight is 20/20. All in all, awesome.

@whomst

Any opinions on PEBA filament? It's not easy to buy, but two manufacturers of it have videos of small bouncy balls compared side by side with TPU, and the PEBA bounces way way better. I've thought it may even be TOO bouncy but I've not tried it out yet. Density is 1.013 g/cm3, which is less substantially less dense than MattFlex 40D or TPC (not to be confused with TPU) so maybe just about the right weight with your models. No idea on its durability though. I fully intend to buy some PEBA and give it a go, but it'll cost > $100 for a single print attempt.

@PartyLime

Somewhere in the comments on the other model page on my profile there's some comments someone who used PEBA. I can't remember the results. More bouncy is definitely better though. The TPC is still not quite as bouncy as a basketball - it's close but still a little off. Would love to see your results if you try it

@whomst

Replying to @PartyLime :

Only comment for PEBA was someone suggesting to try it, but not saying that they did themselves. This is still on my TODO list after I get through a rough patch of overtime at work

@PartyLime

Replying to @whomst :

I can't seem to find the comment. There's one on Printables about someone who is going to try it but then nothing. I'd be interested in how it goes

@Imagine25

I think I might start printing it soon
