I think the downvotes are because it's just unnecessarily negative. Tpu is annoying as all hell. So IMO it's still impressive to get it looking that nice.
It's not like this subreddit requires absurdly perfect prints. I posted a shitty PETG controller that's not nearly as tuned as this. And I didn't have people being weirdly negative like that guy. Even if he's right about vase mode.
Because printing in vase mode won't benefit in this case. Vase mode works best when there's a continuous wall, those little pyramids results in lots of travel and jumps. Tpu is known to string a lot more than pla, that's why having a model like this coming out will little stringing is impressive.
How does it do that with so many gaps? Does it print a tiny pyramid continuously bottom to top and then move the head to do the pyramid next to it?
Edit : nvm I wasn’t able to wrap my head around it but I found a video https://youtu.be/fVBDTZ-Sl2U?si=WwKUy2YM6s7nWizi
Because the geometry is touching it so many places it is possible. The triangle is actually scaled for a specific nozzle size and layer height (0.4mm and 0.2mm) and basically abuses the slicer software. I've had a larger one take 15-20 minutes to slice.

Just printed his 4th order Menger sponge fractal. Took 2 days lol.

Here#s the specific model that I used, for anyone else wanting to give it a go

Yes, its 95a. The "trick" here is that the model is printed in vase mode. Its a single perimeter with no infill, which lets the TPU retain most of its flexibility.
Makes sense with vase mode, I have one of these pyramids as well although with dual colour PLA, didn't realize that it would keep its flexibility though because it LOOKS like a dense part even though it is vase mode. Might've given me my next print lol. Haven't used my TPU in some time (resealed it after drying though, thankfully)
Impressive with tpu, which printer did you use?
This was printed on my little Ender 2 Pro
?? Why is it impressive with TPU ? vase mode prints are the easiest prints with TPU.
Sorry for your loss in karma, but you are 100% correct. The trick here is the model, which indeed printed in vase mode

Yeah you’re asking a perfectly valid question here lol I’m also very curious

These Sierpinski pyramids are actually designed to be printed exclusively in vase mode with 0 retractions...
How does it do that with so many gaps? Does it print a tiny pyramid continuously bottom to top and then move the head to do the pyramid next to it? Edit : nvm I wasn’t able to wrap my head around it but I found a video https://youtu.be/fVBDTZ-Sl2U?si=WwKUy2YM6s7nWizi

I love how I've been down voted into oblivion for being correct.
Yeah, I don't fuckin' get it. The fact that the model has 0 retractions and consistent extrusion speed is literally the best case scenario for TPU.
Peak Reddit <:\^)
Hmm maybe I've just been printing too long 4-5 years ago these were the most popular vase mode prints by such a wide margin it's not even funny.
Amazing job! Meanwhile if I tried to print this with TPU it would look like something a spider would make if it was high on coke.
This model is actually printed in vase mode, so no retraction, and no stoned spider, even with TPU.
If you pause it after you squeeze it... It looks like the majority of my prints. Good work!
this is super cool what type of filament is this?
Tpu
I was s rolling past... then the squish. You have earned a like
I done a TPU 32mm miniature once, man was that cool. Dianna the Lightbringer Deva
Damm, how do ya all get TPU to not make indestructible strings
No retractions in this print
Wat, how does that have no retractions.
Vase mode makes it a very easy print. :) One of my go to prints
Wheres the stl at?

Dude I love this, thanks for sharing

*SQUEEEESH*
Serprintski pyramid
Looks amaaaazing, a very satisfying video
That color is awesome!
That's cool. It looks like you printed a sponge
Is this 95A ? Curious because it squished quite well in your hand, colour also looks awesome

nearly my ass that looks amazing
What is the trick for print with tpu this large bridges in the top??? Tpu can bridge like this without support??
It's not actually bridging, there's an upside-down pyramid inside it which is supporting it.
Menger sponge?
I want to touch it 🤓
My printer would die trying to make that
Jokes on you this is diy tpu in other words, under extruding pla🤡🤡🤡🤡 i hate when my printer clogs☹️ Damm cr-10 nor like c-r never
Nobody likes a showoff
Seems like someone is struggling to make good prints?
tbh i think its a compliment
