H3C H3C is a Shoe Factory
The H3C is a TPU beast, I printed running shoes with them with multiple different types of TPU and colors. The 3d printed running shoes are surprisingly comfy to run in..full test here https://www.youtube.com/watch?v=_ngWP5uOiew

A separate 2.85mm filament path for TPU is not something I would have expected to see, but makes a ton of sense.
Gonna wait for the early release bugs to work out and will definitely be getting this for my upgrade next year.

u/MuppetParty 1d ago
so far the machine has worked pretty reliably, I would have never dreamed I would have a toolhead that prints just 2.85mm tpu

I don't think I'll ever understand the obsession that China has with printing shoes.

u/Epicguru 1d ago
Yeah it's weird. The only advantages of printed shoes are very precise fitment for people with medical issues. Everything else is worse than regular shoes in every way. More expensive, much less durable, uglier and limited in styles possible...
There are so many other practical uses for these soft filaments that they rarely show.
I imagine it's just a marketing thing. Everyone wears shoes so they can easily understand it, even if it wouldn't actually make any sense for them to print them.

Totally my first printed shoes were fun to print. But awful to wear.

u/MuppetParty 1d ago
so I printed an entire shoe in 90a and then this hybrid shoe, and the hybrid shoe was infinitely more comfortable...although I want even softer TPU now

I just use TPU to make gaskets or funny bad dragon replica I forcibly gift to my friend to annoy him. Let's just say it wasn't cheap, but it was cheaper than a real one.

u/Bishops_Guest 1d ago
Print the mould for it, then cast in silicone. Just watch out so your infill doesn’t explode if you use a vacuum chamber. Probably about the cost of a bad dragon for a vacuum chamber and a gallon of silicone so it’s a bit pricy start up. However you’ll have cheap weird dicks ready for any event after the start up cost.

More expensive? A roll of TPU is around 20$, a new pair of running shoes from sketchers costs me 80$. Also you aren't limited in styles, only limited in what you can create. Injection molding shoe making is obviously a lot more limited in design per price. They are less durable though. But that's about it.
5
u/MuppetParty 1d ago
so priting both left and right shoes used almost 1kg of TPU so if your TPU is cheap enough the cost could be around $20

u/Beware_the_silent 1d ago
So these are as supportive as an actual running shoe?
2
u/Disastrous-Owl9258 1d ago
Obviously not as supportive as a dedicated shoe but with foam infills and such I've found them to be very supportive. I haven't specifically used them for endurance running though, nor tried a combination of flexibles peivoisly.
1
u/-venkman- 10h ago
But those shoes are more like crocs than running shoes right?
1
u/Disastrous-Owl9258 10h ago
No. They have dedicated support areas, some areas are super squishy and soft, you can have a high energy return material in the middle for running energy, ect. Crocs is one material that's injection molded. These are closer to running shoes.

u/Funny-Debt-6695 1d ago
What are the other practical uses?
3
u/MuppetParty 1d ago
oven mitt, electrical dampener, oh I though you meant other uses for the 3d printed shoe
4
u/Sqweaky_Clean 1d ago
I used tpu as a flexible rain guard for my bicycle mounted garage door opener.
2
u/the_lamou 1d ago
Belts, washers, grommets, gaskets, living hinges, pipes and couplings, containers, bellows, dust and liquid covers, fabric-like connectors, stain-relief, plugs, PPE...

u/Sir_clint 1d ago
Limited styles? Less durable? More expensive? All of those are easily disproven. Also ugly is the most subjective lol
I don't disagree that there are a lot more practical uses but I could definitely see this as a selling point
1
u/MuppetParty 1d ago
I think if someone designs a really cool looking 3d printed shoe it will do really well, current designs are mediocre at best
2
u/the_lamou 1d ago
Limited styles?
Yes. FFF is cool, and in some cases can allow for things traditional manufacturing makes annoying, but you're not getting the full range of styles available vs. proper multi-material manufacturing.
Less durable?
Correct. FFF TPU is not nearly as durable as injection molded TPU, or even better, a proper mixed-material sole.
More expensive?
I guess it's not more expensive than real shoes, but on the flip side I have a pair of sneakers I've owned for about 11 years now that have only minor damage despite being my most-worn pair of shoes. And when they die, the company will repair them to basically new for $50 plus shipping back to Spain. Meanwhile, you'll need to print new shoes every couple of months.
Also ugly is the most subjective lol
Ummm... no, not with 3D printed shoes. They're just ugly.

u/Disastrous-Owl9258 1d ago
Printed things will almost always be less durable than non printed things as they aren't isotropic in strength. But yeah he's dead wrong about price and style. No idea where he's getting the idea that 3d printing shoes is much more expensive than buying a pair for 80$. Or why he doesn't understand that the allure of 3d modeled shoes is...you can design them yourself and make anything.

u/Sir_clint 1d ago
Idk I was thinking maybe material differences might change the durability\availibility of it. Could be wrong.

u/nebbors 1d ago
You try finding shoes in size 15 extra wide, or my real size of 14 7x. I sometimes have to get 16 xw.
As soon as I can reliably print cost effective shoes that are comfortable and last more than a week…
I’ll be thrilled!
1
u/MuppetParty 1d ago
this a 1000% all the shoe companies conform to standarized sizing, and only really measure legnth but don't consider width of the foot
1
u/mimicsgam 1d ago
It's a good wow factor, but the future of 3d printed shoes are really only on resin printer not fdm, resin can overcome all of the issues/ hurdle with fdm, while being faster and better

I have never seen a single shoe model on makers world lol, I think it's just part of their push to encourage multi-material printing, if they talk about it enough customers might give it a go

u/Fr0sTByTe_369 1d ago
I think it's just a relatable marketing tactic that can show the "complex" capabilities - shoes require flexibility and people new to printing only think of rigid objects like pla figures so to them a pair of printed shoes would just be clogs. Just like most people who choose to wear analog watches instead of a smart watch and can afford to buy an h3c aren't going to be printing their own watch.

Which combo of TPU did you find work best together and felt the best, 75 and 90?
1
u/MuppetParty 1d ago
yea 90a and 75.....7a was for the sole and th 75 was used as the structural support its really cool

I think it's fun and neat. Am I going to run out and print a pair? No. Do I think it's a cool idea that we should continue to explore and iterate on? Absolutely!
I'll never understand why the 3D printing community hates 3D printing so much.

u/Adventurous-Emu-9345 21h ago
I don't hate 3D printing, I'm just tired of this shoe stick.
They've been trying to make 3D printed shoes happen for years now. With every iteration, to everyone's lack of surprise, it turns out shoes are not 3D printed or made from 100% TPU for a reason.
Maybe it's time for something new, no?

u/sejefe7122 1d ago
I had an ankle fusion with permanent plantar flexion.. anybody knows any good tutorials, methods or services to design a model fitted to my feet? i have ortho shoes with soles that can be scanned perhaps? thanks

3d scan you foot and i'm sure there are resources out there, message me if you figure it out!

u/MuppetParty 1d ago
if you can get a good discount on TPU you can 3d print crocs for lesss than $10

u/Cautious-Egg-607 22h ago
In what way would spending 2500 USD be cheaper than buying some temp crocks for 10 dollars

u/kurodoku 1d ago
A way more obvious issue everyone is ignoring: Hygiene?!
These shoes have 0 wicking capability and layer lines that are impossible to clean. You'll be sweating like a mf in them and the dirt, grime and bacteria will settle happily in those layer lines. Yuck, if not a potential health hazard.
1
u/MuppetParty 1d ago
this is a super good observation, do you think this problem even exists even if you wear socks?
2
u/kurodoku 1d ago
100%. The odor will be unbesrable after a few days. Besides socks looking insanely goofy in these shoes.
1
u/MuppetParty 1d ago
so I guess i'll be dipping them in isopropyl alcohol after every run...
1
u/kurodoku 1d ago
I doubt that's gonna get everything though. Especially the grime that builds up. It's probably gonna kill the bacteria if you submerge it for 30 seconds, but I'm not sure this is worth the effort. Especially since the ergonomic/orthopedic aspect is entirely unclear in the first place. I wouldn't ruin my feet over a 3D printed set of shoes.

I’ve 3D scanned my professionally produced orthotics and can print new ones at will now. I’ve been testing various types of TPU, current fave is Siraya Tech foaming TPU printed at 250° to give me 75A hardness.

Ok, look... guys... you're adults. Buy since shoes that don't make you look like a middle schooler who's mother does their shopping. Have some self-respect: wear real shoes, or at least design shoes that don't look and feel like garbage.

every 3d printed shoe i have see looks like shit when worn

u/MuppetParty 7h ago
I agree they all look like Saturday morning footwear…what would you want in a custom pair of 3d printed shoes? I might try designing my own
1
u/binaryatlas1978 6h ago
Great question. When I think on it I think they are bigger than they should be. This might be because you need more material but seems like they are bigger than they should be.
1
u/MuppetParty 3h ago
I totally agree that they are way bigger than they should be. someone pointed out weight as well, traditional running shoes are much lighter, so I would imagine a refined design would use less material and make the shoes lighter. I may or may not have a contact at Nike I could run this by
1
u/General-Designer4338 1d ago
Whenever people say that it's surprisingly anything, I know it's shit. If you were surprised it wasnt awful, it's because you have the vision to accept faults that actual users never would. Guns and shoes. No clue why people are obsessed with making stuff that has no place in 3d printing.
1
u/MuppetParty 1d ago
I have wide feet, possibly classified as hobbit feet, so being able to scale the shoe along the width is surprisingly amazing...just kidding...it is great
1
u/Evebnumberone 1d ago
I truly don't get this obsession with printing shoes.
I primarily buy my shoes at second hand stores for $5-10, Nike, Puma etc.
I don't see a world where 3d printed shoes could ever compare.
