I've been 3D printing for about 8 years now, and one thing you may want to try is changing the infill patter, which could affect the squishiness and feel under foot.
As others have probably said… 1) change infill at different parts of the model (easy in PrusaSlicer), 2) use a bigger nozzle like a .6 or .8mm and 3) 0.15mm layer height is tiny, am sure you’d get good-enough results with 0.3 on a 0.6mm nozzle will print in fraction of the time
Your cr 10 printer will inherently be stringy when trying to print flexible filaments. This is due to it being a bowden style extruder instead of a direct drive extruder on the prusa. You should try using progressive infill so there is more infill at the sole and less infill on the top where the infill does not matter. The infill pattern you should use is the gyroid pattern.
wait, this series of 3D printing is amazing. even if none of the DIY projects matched an authentic pair it's super fun, educational and interesting. thank you for getting into this, seth! 👍🏽
Thank you so much for continuing to be the only person to fill this niche for me. I hope you keep it up! I'd love a video series on you designing your own slide, and adjusting parameters and things to make them actually viable.
In Prusa Slicer you can add modifiers to change the infill at different parts of the sole. i.e 60% for the heel 30% for the toe and 50% for the arch. Also you can use another model as the modifier to get a better shape. The rabit hole is deep. Great video. Keep up the good work.
With the support, figure out a good angle for printing the shoe. Angled slightly at anything less than 30 degrees will help with an overhang. You're essentially trying to make a bridge so stringing will occur.
SETH!! Instead of printing out full slides with different infills, maybe try printing a bunch of small cubes with different infill types for you to test out, then once you find one you like you can print a full shoe with it. That way you can save time and money!! I’m loving the project and hope you somehow help change the shoe game with these, the possibilities are endless!! 🙌🤙
With your Prusa Slicer, you can have different infill amounts at different layers, so you can make the bottom high infill and then low infill once it's past the base.
I highly recommend gyroid infill (you’ll still have to iterate to get the percentage just right though), and a 0.8mm or 0.6mm nozzle. Will be much quicker print and still look just as good. Gyroid is better for unilateral strength too.
Stringiness isn't normally solved by supports. They are typically due to retraction and priming settings. Additionally travel speed has a significant impact on this as well.
I would defiantly increase the infill % and change it to a "3d" infill pattern so that its more uniform. Also i would wary the infill % between the sole and the rest of it, so that the sole is more solid solid and the rest of it is a bit more soft. Would love a pt 2.
I think F80 rubber resin on an SLA printer could get you pretty close. I haven't gotten too deep with TPU on FDM machines but that F80 resin has been killer for rubbery type of projects
I'm glad you're still doing this. You should try printing out some flat slabs that you can stand on so you can test different types of infills and densities. That should save you some print time since it's a simple shape and will use less material
Suggestion, With Prusa you can use certain modifications to make a 3d model slice with one type of infill, and then another part of the model slice with another type of infill. Id suggest looking into that, so you could say make the heel area thicker in infill (and id say look into using gyroid infill because it might have better cusioning) and have the front area have less infill. Same with layer thickness, you can make the bottom layers have thicker walls while leaving the upper layers with thinner walls. Theres a lot of options for you to use instead of one infill prints all. Edit: Other suggestion, theres printer profiles in the Prusa Slicer for creality printers, take a look at them since Prusa slicer is a better slicer then the creality one.
i dont know if this is possible, but in 11:16 you metioned the "pocket of air squeezing", maybe there is a way to post process tpu filament prints to fuse the gap between layers, maybe this would make shoes more stiff and create feeling like 'walking on air' ? i know that people are using ipa fumes/acetone to smooth the petg prints. Really enjoy the shoes printing series, keep grinding 👍🏽
I would suggest changing your infill pattern to "Cuboid". It offers strength in all directions. I also would experiment with increasing your wall count. One thing you can do is just print out the soles. It will take less time and you can experiment with different settings and nail the right stiffness.
Glow in the dark fillament will degrade your nozzle super fast. If your prints start to suck get a hardened steel nozzle, you'll be able to print abrasive glow in the dark fillament
Very cool, try a larger nozzle and a thicker filament, I may speed things up a little. And there is free software you can use for slicing that allows you to place different infill amounts in different places of the build. 🤞
Use your scan in an editor like meshmixer, and subtract it from a block to make a negative space. Then you can chop that into pieces to make mold halves. Get some two-part rubber or silicone and cast these, and you can get the firmness and flexibility all in one.
im from the 3d printing community and i would recommend changing the infillpatern, and instead of using supports that stand on the insoles, try to orientate it kinda upside down and vertically so there are just supports touching the printbed
Maybe change not just the infill but the number of walls too, if you put a high number of walls with a low infill it may be soft in the middle and not crush under the weight on the sides, I don't know if I explained it correctly but I think it would have a good result
BambuLab X1 will print these at least twice as fast, especially if you consider changing the nozzle diameter. If you are using 0.4mm, consider 0.6 or 0.8 for a drastic speed-up. 0.8mm would be close to twice as fast, especially if you up your layer height to .3-.4
I think you have to separate the top and the bottom part. The top part can be a really nicely knitted flexible sock, and you can add other things that stabilize the whole shoe.
One recommendation I have would be to move to "gyroid" infill. I find that it prints quickly, and is far more regular in terms of structure ta cubic infill... at about 15% it would probably be great here.
3:37 pro tip: dont use the creality slicer. it sucks and is based on an some older version of cura. Just use the lastest version of cura and the built in profiles for the printer or even prusaslicer and it should have built in profiles for a bunch of creality printers.
Probably a weird suggestion but maybe make a block with a cut out of the yeezy slide (A mold) and try filling it with expanding foam to see if you can create an actual foam version!
you should try the bambu labs p1s or max and see if you can do the soles as slid material and the inside as a softer material before finishing with a style material around the top. I recommend that printer because it can handle multiple materials with its AMS system as once.
From my own shoes I made I found 13% infill with 4 print lines for the outer wall for 130lbs works great for daily use using poly maker TPU When wearing for cross country running, and intense tug a war the outer wall layers split or were too flexible. This was solved by welding the tears closed and welding to make the sides thicker. The sole will not squish out air when properly re-sealed The redesign of the shoes will have thicker walls in all the non flex spots Print time is 4days
Btw just a small thing I would not recommend using the creality slicer even tho you are using a creality printer. It's outdated. What I would rather recommend you use is whatever you are using for your Prusa. (Not sure if you are using Cura or Prusa slicer) but both of them have profiles for your printer from what I know and they should make your experience much better with basically everything. Also they are better at slicing because they both have better algorythms under the hood.
About the infill situation if your using cura to splice your prints you should change the infill type instead of more infill. I believe the default is cubic but I recommend using gyroid it’s more structure do you won’t need more infill
IM really loving these 3D printing series, I've always been so interested in it, since its another form of art in my opinion but with technology! love it, keep going Seth!
I do recommend printing in a boxed environment with a vent shaft attached due to toxic chemicals released in the air from heating the filaments. As far as the first print goes, with a dremel and fine sandpaper you can shape up the details nicely.
creality slicer is a really old version of Cura. you will have much better results if you update to the latest version of Cura or just slice in prusa slicer for your creality printer.
You should drop that support density like CRAZY, and use support trees in Cura, or use Meshmixer to Analyze Overhangs and generate supports using their tool, then import to your final slicer and finish the slicing there for your final .gcode. Also use support blockers if needed. And something tells me....you should try gyroid infill instead of grid or lines.... 👍
is it possible to use both machines for one slide? layer by layer? have the stronger base/ stiffer base for the soul but then mid print use the ninja flex where your foot sits and the upper half of the slide, we need a part 2
I commented on your first 3D video where YT pulled me in based on algorithm's. Well they stuck cause I have now watched all the 3D printed videos. You are quickly getting into the world of 3D printing. Infill is a beast when you really learn what all is available and can be done. Neat to see you work your way through the iterations. Still haven't subbed but getting there, lol.
You can fix stringyness with retraction But I wouldn't actually do that because you're using flexible filament, what I would do is print them without support, and then use a lighter to burn off the strings
You need to mess with changing the infill throughout the print. Probably need >50% for the sole of the shoe and then set it low for the insole and foot cover. You could try upgrading the ender printer with a direct drive extruder so it can print faster too.
I feel like you're making the infill too low. I think you should switch to tri-hexagons and increase it. I know it takes longer, but I feel like they keep caving in on the heel, so it would be worth it.
I highly suggest joining the 3d printing discord and getting access to the what printer should I buy sheet. You want something with a PEI sheet bed (so you can peel it off and not have to struggle to get it off the glass
Next time, try printing em sideways so the in-fill pattern prints sideways as well so it doesn't look weird when it collapses on itself. Nice video series btw
the sole thickness difference is probably because scanned shoe was smaller size - they dont just scale them in all axes when making bigger shoe sizes... You can play with scaling and lower Z percentage...
I would recommend an idex printer to use dissolvable filament for support. The IDEX printer optimally use dual direct drive extruders. Something like the Soval IDEX printer.
Soval SV04 IDEX printer would be my recommendation. You will need to calibrate it some what but using flexible and a dissolvable filament would make support removal super clean.
There's a way to print an object with different infill % Example you can print about 1 to 2 inches with 30% Infill and after that set hight you can lower the infill to something like 15%. Might help with the heel support and co fort. Would make a great video.

Great call! I’ll try that!
@@SethFowler iirc gyroid is what a lot of people use
i wanna start 3d printing but i do not wanna spend over like 300-400$ for a good printer, what should i buy?
@@SethFowler cant wait for the next video
@@SethFowler Instead of printing an entire slide maybe you could print multiple soles with different infill patterns? Just a thought.

You can do this in Cura too.

This is soooo wild! 🫶🔥
Very cool, try a larger nozzle and a thicker filament, I may speed things up a little. And there is free software you can use for slicing that allows you to place different infill amounts in different places of the build. 🤞
an easy and practical thing would be printing a phone case

In your slicer you should select the sole of the shoe and change the infill to be a little more dense, then for the top have thin it out for softness.
Can't wait to see you try the foam runner next

Creality slicer is an older forked version of Cura. Though I agree he should switch to the real Cura preferably 5.0 or newer.
I love your vids, I've Been Watching Both of The $20 Sneaker Collection Series And It Seems Like Such A Fun Thing To Do.
About the infill situation if your using cura to splice your prints you should change the infill type instead of more infill. I believe the default is cubic but I recommend using gyroid it’s more structure do you won’t need more infill
So are you actually going to make a follow up video where you tune the shoes to be comfortable? That might be interesting.
IM really loving these 3D printing series, I've always been so interested in it, since its another form of art in my opinion but with technology! love it, keep going Seth!
This is cool, could you use a more sturdy material for the infill and then the softer material for the remainder of the slide?
another thing might be to make molds from the 3d printed objects then casting them with foam. Plus printing in TPU is way easier than PLA
Double or triple the wall width. And maybe just increase the infill to 20-30% should be a good fit.
I do recommend printing in a boxed environment with a vent shaft attached due to toxic chemicals released in the air from heating the filaments. As far as the first print goes, with a dremel and fine sandpaper you can shape up the details nicely.
He used tpu which doesn’t use toxic chemicals, but abs does😊
It's crazy the applications 3d printing has. The limit is your brain to be honest.

4:07 just click the "i" button abbove the "save to file" and youll see how much time the printer spends on each part. like, support, infill etc...
research the digital foam videos
use support blockers in heel area to increase infill to 30 -40 percent in that area only

I feel like you're making the infill too low. I think you should switch to tri-hexagons and increase it. I know it takes longer, but I feel like they keep caving in on the heel, so it would be worth it.
The angle at which the filament enters your extruder on the cr10 is painful. That 90° turn adds a lot of friction that you don't need.
You can use a lighter to remove the stringiness
