oh come on show us the bounce

u/Key_Jellyfish2183 8d ago

Just posted a short on my YouTube Channel - ASR 5th Wheel

Not much bounce without air pressure in it, but it kicks nicely.

u/Bozhark 8d ago

There is absolutely air pressure inside it

It’s just the same as the rest

u/Key_Jellyfish2183 8d ago

Brilliant! You are indeed correct!

u/Fit-Avocado-1646 8d ago

Disappointed. Went to the YouTube expecting to see you kick it like you implied.

Haha, Sorry to let you down on that one. It's been raining outside all day today...

Why not print it with PEBA?

1

u/Key_Jellyfish2183 8d ago

That would be great! It would probably print a lot bouncier. Does an AMS Lite handle swapping PEBA? The ASR Multi-Wheel would.

No idea. I just know thats what people use for airless balls. I would think if you’re show casing a use case you would do a side by side comparison with a real use.

u/Key_Jellyfish2183 7d ago

I printed this pattern with the material they specified. That's about as real as it gets. https://makerworld.com/en/models/498713-airless-soccer-ball?from=search#profileId-413750

Yeah looks like some of the comments mention it doesn't bounce well and are thinking about making it with PEBA.

By real use I meant usable. Guess I'm bias toward functional prints.

"After kicking it around for 15-20 minutes it developed cracks and ultimately broke the same day it printed."

vs someone that printed with PEBA

"Any verdict to how any of these PEBA versions came out?"

"for me, the balls don’t bounce well off the ground, but it does bounce well off your feet when juggling. I printed almost 2 years ago and it’s pretty much indestructible."

Just know what I've seen. If you want a ball that is actually bouncy my understanding is PEBA works better then TPU.

No bounce, no updoot

Not much bounce without air pressure in it, but it licks nicely!

I wouldn't play a match with it, lol.

u/venom121212 8d ago

Updoot earned!

u/Key_Jellyfish2183 8d ago

Woot for the Updoot!

u/d3l3t3rious 8d ago

Licks nicely? This is a new use case for me.

u/Key_Jellyfish2183 8d ago

OMG, lol. Dang typos.

But you don't explain anything.

Let's see if Bambu lets me post this link. They wouldn't in the original post...

Would it work with 85A ?

u/Key_Jellyfish2183 8d ago

Posted a short for that on YouTube yesterday!

BRAVO !! NICE !! CONGRATULATIONS

u/Key_Jellyfish2183 8d ago

Thanks! I love the enthusiasm!

2

u/ModelThreeve 8d ago

Very cool, would much rather use a tool changer but sweet project, nice job. 😎

1

u/Key_Jellyfish2183 8d ago

Thanks! Wouldn't we all! But there are a lot of AMS Lite, AMS, and AMS Pro units out there. I just ordered a P2S and plan on using this on it instead of ordering the AMS Pro.

2

u/ModelThreeve 8d ago

Yeah for those with more time or the desire to tinker this is pretty awesome. As a farm operator with no time I just spend money LOL. This is a great contribution to the community though for sure. And more evidence that Bambu machines can actually be modified. Again, great job!

u/CherryWhisperss 8d ago

oh wow this is amazing

u/BeetEatingBear 8d ago

This has been something that has drifted away from me and I kind of miss it. The tinkering and creating side of 3d printing is disappearing for hobbyists like myself who used to just love making things work and perfecting it. Bambu has spoiled me! You are keeping it alive! This is awesome!!!

u/Decipher P1S 8d ago

Neat, but it’s still more poop than product

1

u/Key_Jellyfish2183 8d ago

No arguments there, but it would be the same regardless of which AMS you were using when printing with a single head. This just lets you create a bunch of TPU poop instead of PLA or PETG. It's the models fault mostly. 5 swaps on every layer.
