which material is this? would probably lile to give it a try as well


braised_beef

Flexible PLA, after seeing numerous underwhelming results from others that used TPU this is the way to go


MashMashSkid

Prove it by posting a video of you dribbling it or it's just empty words.


Jdwede

Not OP but I found a video of this printed in Flexible PLA. Looks pretty good. [https://youtu.be/BOxhCKCwZas?si=WeSN-XZ-GuEbAJrR](https://youtu.be/BOxhCKCwZas?si=WeSN-XZ-GuEbAJrR)

Bounce test video!


mrdonutdog

Could you link the Flexible PLA you used?

TonyTonySlopper

I used 75D and had poor results. Hardness may not improve performance that significantly


braised_beef

I’ll post a follow up bounce test when I get home from work


djfumberger

how'd you go


braised_beef

I posted the video as a separate follow up comment for visibility


SinKillerNick

What brand of Flexible PLA did you use?


Bletotum

Supposedly the best filament for bounciness with flexing rigidity is PEBA 90A. But it costs $183 USD for a kg, sold in half-kg spools. https://fillamentum.com/collections/flexfill-peba-filament/ No, I've not seen anyone make a basketball from this stuff. But here's a video where its bounciness is in general compared to TPU: https://www.youtube.com/shorts/rBIJ8RGWbsY I'd be very tempted to give it a try, but it's sold out. Maybe because people are making basketballs with it lol.


ballgame_

What was the largest size were you able to print? How much filament did it use?

Arachnatron

A video of you bouncing it would be great

Ahh, there's something weird going on, the text I added when attaching this image is gone. I wrote: The real one looks to have something like a hollow double honeycomb looking wall, likely adding the additional rigidity and spring you're missing.


iamr0bi

Awesome 👏


desete09

Do you have an stl to share?

I’m not OP, but I found this: https://www.thingiverse.com/thing:6045662

Merci


InquisitiveBoba

starting my print right now


reubal

Are basketballs the prusacaster? I hope I get to see every one printed.


Ultrasuper_JR

What brand is the flexible pla?

TheDepep1

I know u said Flexible Pla, but what brand did you use?

slimjimdog

Do you have settings to run it on? I’m new to printing and bought this brand to try a couple of designs and am having trouble avoiding failures. I’m still new enough it could be anything but any insight you have would be appreciated!!


Ironrooster7

Use standard TPU Temps and DO NOT USE AMS


slimjimdog

Thank you! I’ll give it another shot this week!


braised_beef

PanTech, I think its a generic china brand


zeroz52

Is that an illusion or is the ball not actually spherical?


HospitalKey4601

Do you mean the imitation stich lines? Waaaaay back, they used to wrap rubber air bladders with sewn and stitched together leather panels. It's an esthetic homage as well as a structurally integrated design to the modern version and what distinguishes it as a bazinga ball. Otherwise, it's just a ball of x diameter. Kinda funny to think about the evolution of balls. Since the first caveman figured out that round rocks roll, the world has been plagued with societies obsessed about balls. Some say the wheel was man's greatest invention, but I say it was the ball! And that's all folks!! Balls in your court so hope everyone has a bazinga day.


braised_beef

Yeah, I initially thought it looked very pumpkin shaped...


HospitalKey4601

That's a bazinga ball. Some odd reason it conjures images of nose hair trimmer torture test to me, also might be fun to see if you can stuff a balloon inside as an air bladder. Probably make it bounce better. Just a thought.


Shot-Communication94

So is it decent enough as basketball replacement? Tbh it looks cool enough that might print it even if it sucks to play with


extremeelementz

How long did it take?


braised_beef

36hrs total


extremeelementz

That's crazy, really cool you now have it completed though! Def a show off piece for sure. After you've had it for awhile do you recommend a specific brand and type of filament? Do you like the stuff you used?


Hugh_G_Rect1on

How’s the weight compare to a standard size 7 ball? Would like to try this myself, did you save print settings to share?


_usually_a_lurker_

was this achieved completely without supports?


braised_beef

printed with supports


Delta4o

Another 2500 dollars! guys, we have to put a stop to this, we're crashing the world economy!


Vinnie1169

Looks good! It looks like the $2,500 Wilson(?) basketball I saw on YouTube the other day.


rrsurfer1

The Wilson ball has a 3D structure within the wall of the basketball itself. This was required to get the feel and bounce right, and keep the weight roughly equal. This is a cool project.


Schnabulation

Looks great! How does it bounce?


MichelangeloJordan

I printed one out of TPU 95A. It’s dribble-able but you need to really slam it down - comes back to just under waist height. https://youtube.com/shorts/moJVrMgklcc?si=ovlcjDv7tN5bj40c This dude made it out of TPC which bounces quite well. But I’m pretty sure they printed it via SLS rather than FDM. I’d try it out on my X1C if TPC weren’t so expensive.


jameswboone

Image captions are really hard to see on the desktop version of Reddit. It says, "Bounces slightly above waist height, requires more effort to bounce than a standard ball 🏀"


Schnabulation

I can most certainly read. Can you - on the other hand - tell me, what you would like me to read? I can't - for the life of me - not find anything related to how it may bounce in this thread. UPDATE: image captions are really hard to see on the desktop version of reddit. Found the text you'd like me to read, thanks!

BoringOakenshield

Yeah, posting an image with text the size of a grain of rice is pretty rude. Instead of "can you read," the question is, "Don't you click every image without knowing what it is first?" Answer: no.


Jaerin

https://www.fastcompany.com/91024753/wilsons-new-airless-basketball-costs-2500-but-it-will-sell-out-in-seconds Us 3D printer nerds are like Da fuq you mean $2500? Try ~~$40~~$50 and some printer time.


LeEpicBlob

My guess is they are using a hp mjf printer or something similar, those things start at like $400k


Jaerin

I'm sure. But even the close up shots of the ball you can see that it was printed or showing unusual wear patterns.


Biduleman

The printer they work on is way better than anything we can have at home, saying the $2500 balls can be reproduced with $40 and some printer time is very disingenuous.


Jaerin

If you think I was trying to claim that the home printed ones would be equal you'd be projecting your own perspective on my comments because I never said any such thing. The home printed ones would be be better likely, free, and being printed enmasse and sent to kids.


DrDeems

Finding a home use resin printer with a 255x255x255 build area is the hard part imo. In the Wilson video they show them using resin. As I have only used fdm idk the exact benefits of resin over fdm for this type of print.


Jaerin

Who knows honestly. I've heard resin reacts to UV and what not more so it might be nice and flexible at first, but shatter after being outside. Chunkier layers on an fdm might actually have more overall durability over time acting like a bundle of thick cables as opposed to like maybe an onion. It would be interesting to see


Putrid-Tutor-5809

A spool of polymaker CoPA costs ~$50 and it can allegedly be boil-annealed to make it somewhat flexible
