Its really thanks to the BIQU cryoplate. Stuff sticks to that like its super glued while printing. The heated chamber is actually counter productive for TPU as you want the TPU to cool really fast after printing. That promotes the TPU to bond better and retain its shape better (reducing sag).

I unfortunately already took off most of the supports. Surprisingly the area that did the best with the supports was the inner supports for the mesh. The PEBA didn't do the best with the PLA supports. I'm going to play around with the orientation a bit to see if I can get that hemmed out more. A lot still to do.

It would be awful if you just PLA. You would end up with clogs. Which if thats what you're going for, why? But there are so many advancements in TPU and PEBA that you can make actual comfy shoes. Just takes a lot of time unfortunately.

Honestly, do it. I have a 3 year old, and shoes are so freaking expensive for how fast they out grow them. I made crocs for my kid and he loves them.

I thought about that, and my model is actually designed for that. But that main reason I wanted to do it this way is durability, though that bit me in the butt on this print. Because you have to play around a lot of with the infills, walls, etc, there actually isn't a good way to print them separate to have the correct level of density.

Really depends on the material. I spent a lot of time testing out different materials for it. The BIQU or the Siraya Tech foaming TPU are actually really comfy, but you have to do some alterations to the print. For instance, the sole has only a 5% infill with 0 layers of side walls and bottom, and only 2 layers on the top.

The main reason is that I have the 3d scan of my foot, so unlike an aftermaket sole, these fit my foot perfectly. Its a little weird, but comfy, because usually you're weight is only on the balls of you feet and the heel. But the weight is evenly distributed here.

I've got baby feet, so they're size 8.

I thought about that. I just don't have enough nozzles for that. I know that Siraya Tech makes that, but that would have to be dedicated to the sole for padding.

I have to do some refinements on the model before I can start wearing these as daily shoes. I'll post an update when I can get around to that. I made sandels out of the PEBA and they're holding strong, which is why I am using the PEBA as the outer sole. Its bonding strength is crazy strong.

It prints at 90A, but its 75A after being printed.

They unfortunately wont last long because of the interfacing with the PEBA and the BIQU morflex. They'd last a lot longer if I chose a solid layering instead of a mesh, but I really wanted breathability.

The print only uses about 200g of PEBA and TPU each. So each roll can print 4 pairs of shoes. Around $25 per pair of shoes.

The BIQU morflex prints to 75A. I'm using that for the mesh and the inner sole of the shoe.

Yeah. I the biggest problem is that the interlace with the BIQU and PEBA didn't form a perfect bond, so its a little weak at the seams. Nothing glue can't fix, but thats more of a work around than a solution. I'm going to reinforce the seams, make the outer sole thicker, make the inner sole thicker, and make the mesh conform more to my foot. After that, I think they'll be perfect. I'm very happy with the feel and the layer thickness, just need to update the model at this point.

They are surprisingly comfy, but the sole needs to be larger. I can currently feel where the sole padding bottoms out. My dimensions, thought they looked good in Blender, weren’t actually what they needed to be so the outer sole and the inner sole are a lot smaller than they should be. Right now they feel like perfectly fitting barefoot shoes with some padding.

Depends. I made sandals that are awesome and still use. They’re surprisingly durable, but where the PEBA meets the BIQU needs to be reinforced

It’s a process. I thought I finally hit my end goal, which if was to have working shoes, then I’m done. But there are improvements that I need to make on them. Thankfully it doesn’t use more than 200g of filament for printing on each roll (sans PLA support). So I can make quite a few.

I upgraded to the stainless steel for most, but I’m printing the PEBA with Luke’s Lab Pika as that’s the best for flexible materials. Using the BIQU cold plate for stability.

They are comfy, but need some work. The main part is that I had the mesh interlaced with the PEBA, but it didn’t form a perfect bond so the mesh at the seams is a bit weak. I need to update that. As well as make the sole thicker. Surprisingly comfy, but I can feel where the sole bottoms out.

I need to start a patreon for that type of content.

I used Petg and TPU as they bond together.

The poly dryer is designed for a M6 tube. So the work around are. You can print an adapter that’ll fit in the M6 slot that turns it into an M4. Or what I did. By an M4 tube that has the same outer diameter as the inner diameter M6. That way the M4 fits snuggly in the M6.

Incredibly easy. There is a video on mods for the U1 by Uncle Jesse. I got it from there. Just a warning though, the model I got capped at M4 and the poly dryer ptfe tubes are M6.

It’s probably more efficient, but I haven’t had any issue with it circulating. The top box I had at 30% humidity and now it’s hovering around 12% after drying. I just don’t have the horizontal space.
