You need to use cubic or gyroid infill rather than the square infill. That will help the stability of the actual shoe. I would recommend gyroid as it would retain the flexibility while also being more stable.

To me, the potential of 3d printed shoes is in making custom fittings based on 3d scans of your feet

I print a lot of TPU for my online business. All of our products are TPU. TPU has very different physical characteristics depending on how it's printed. For soles, I'd print 4 mm on the bottom, 4 perimeter layers, 25% infill and 3 mm for the insole. For the uppers I'd print 2 outer layers (.9 mm) and 10-25% infill. You don't need expensive and difficult to print low durometer TPU for most flexible parts. Use 95A TPU and reduce the outer layers to get the flexibility you need. The only caveat would be enough layers for durability without being too stiff.

Some time ago I was also playing around with pretty much the same shoe files and one thing to keep in mind is the settings for printing the soles.
I would recommend setting multiple solid bottom layers, depends to the nozzle and layer size used this would differ but it is good idea to have at least 2mm solid layes at the bottom, better 3-4mm, then middle of the sole can be with least infill and the top part of the sole with a little more.
The idea is to have a good bottom which can handle the abuse and prevent getting pierced by glass, nails or whatever on the ground, soft middle that will make it springy and comfy and then be a bit more rigid at the top so that the foot won't just sink in too much.
I got best results using honeycomb for the infill, 3mm solid bottom with 20% infill in the middle and then 40% at the top.

Man Dave absolutely killed it with his design. You should get into contact with him for a custom Seth Fowler 3D shoe.

To anyone that does 3D print, the main thing that people don't talk about is the air that melting the filament produces. There have been multiple studies that link them to cause cancer. Please be safe and print in a well ventilated area!!

[himom]

good video as always. Next time print with 30-50% infill so the insole doesn't just collapse due to being empty. Enjoyable watch.

Seems like this is maybe not very realistic for sneakers, but for slides or house slippers I can see 3D printing having a lot of potential…

[CoolAsFreya]

As you further explore 3D printed shoes you should look into variable infill, for a shoe sole you want different parts to have different amounts of flex and support, which can be done by varying the density of the infill in specific areas!

So glad that you are getting into 3D printing!

Would love to see a sole cushion comfort design contests 4x a vid one vid a week, this would really start to push 3d printed shoes into a more realistic idea going forward as well.

[alanbarnett]

I'm so glad you're still doing this! I'd love to see you work on the design for an actually good, nice looking 3d printed shoe.

[matejgrim]

I would love if you expanded on this and made some awesome, innovative shoes in the future! I'm a fan of 3d printing and I really like the idea of making your own shoes nobody has.

[Abdullatifracing]

I made 3d printed shoes for my final year project at uni! Managed to get sole feeling like a normal shoe!

[morphinebeats]

5:10 - "I''m not seen.." (silence as you see something of interest)... "...really much at all"

[Smileslifeetsy]

you should put some (flex seal) on the bottom for wear and tear.

[mrfelipehurtado]

This should be your new series, contacting other 3D print designers and creating something like those Adidas with the printed midsole

[Rockwell]

Cool man! Saw your first shoe vid and left a comment looking for ver 2.0 this is a neat segway but I’d still like to see your second version design!

[williamhuang]

I think PrusaSlicer supports different infill densities by height so you can make the sole more dense.

[Skylionfpv]

you need more infill for the bottoms of the shoes to stop them from collapsing, also your creality printer could use a direct drive upgrade to print flexible filaments better
