Can 3D PRINTED hiking sandals survive the jungle?

[@SunChaserEUC]

Should be an option to go back a layer or two in a print and resume from there.

[@MorleyKert]

I know, right?!

[@thenextension9160]

You just tell the software to start at a certain layer in the preview pane. The green bar can be dragged on the right. Which tells the code where to start.

[@Villecubing]

CNC Kitchen made a great video on how to resume a failed print

[@JesperMakes]

I really love how this is both an indept 3D printing tutorial AND a crazy adventure into the wild!

[@alexanderkappreumert]

When other maker-youtubers recommend something, you know it's gold!

[@ale6242]

Speaking of things you wear. i 3D printed my glasses frames after finding the ones i had picked in the store to be uncomfortable. I wear them every single day and love them. I get compliments on them all the time and peoples minds are always blown when i tell them they're 3D printed

[@thenextension9160]

This was pretty funny to watch. Winging it but positive all the way.

[@eLeoLychen]

Oh man I really wanna see you do further permutations on this design, the process is fascinating!

[@kazolar]

I've tried doing this some years back. I had scans of the foot and used that as my reference, and I also used the sculpting environment to get a more organic shape. Definitely would not go with 100% infill, anything about 60% for TPU is overkill, and likely the cause of the clogs. Also would have gone with a large nozzle, the sandal doesn't have that many fine features, so a bigger nozzle would have mitigated the amount of clogs as well and doing both -- lower infill, and a larger nozzle would allow you to print these faster. Very impressed that you made it through the vacation and didn't give up on these. Big props.

[@georgesenju8665]

I would love to see another version with the improvements you’ve learned!

[@XopherNiven]

I would also like to see that. Maybe higher bottom layer count with only 35% infill might give it ruggedness and durability all the while being able to print faster.

[@JesseProjects]

Anybody else yelling "just print it on paper!" at 2:00? Might be a bit cheaper/faster test of the size-to-foot comparison, lol. Joking aside, great work, as always, Morley!

[@RivLoveshine]

I wanna be in the tropical rainforest! I've always loved jungles! They've been my favorite biome ever since I was little.

[@TroyRubert]

Man, I used to live there, and I miss it so much. The people are the kindest, most welcoming people in the world. Pura Vida!

[@MorleyKert]

Everyone we met was incredibly nice and generous.

[@rickalcantara]

You should've used some infill, 100% is too much. I used to make some insoles and we used 25% at maximum, and it was still very rigid. Anyways! Love your videos, excellent job!

[@Luigik99tv]

Yeah I agree !

[@PauIieWalnuts]

If you cross section those Chacos, I bet it's a grid pattern in the middle, with a thick insole and outsole

[@xanderwusky]

Agreed, it would also make them more bendable, lighter and easier to print. What might also be a good middle ground is printing only the lowest part of the sole solid. As it would maybe help a bit with lasting longer. But then only do like the first 5-10mm

[@yuriylutsyshyn3495]

Thank you for the colors, we struggle here so much, hello from Ukraine. Enjoying your videos!!.

[@josephvitale4357]

Great video, It provides an excellent in-depth explanation of the design process used in creating the sandals. I like it because it is not something you usually see on You Tube , a detailed step by step tutorial.

[@MorleyKert]

Thanks for the feedback!

[@CH1CK3NNU66375]

You need to glue some water wicking material to the top layer of the sandals for extra grip.

[@testingapril]

The buildup to this video had me anticipating it. And it paid off! I'd love to see you refine it and give it another go. It would be interesting to watch your rapid iteration testing approach from your free 3d peint fix videos with these sandals. Maybe the goal could be adapting to a different size shoe for someone else once you have it more functional?

[@Rouverius]

Yeah, real world testing is a must. Hey, maybe a follow-up project one day with design improvements? Finally, Happy Birthday, Mrs. Cathy!

[@Keasbeysknight]

These are the types of things I look forward to in the future. Once 3d scanners are super affordable alot of things like this can be brought to the masses. Jetsons here we come!

[@joakim3964]

I just want to say, I actually dont care about 3D printing, I just like your woodworking videos, but I watched this video anyway because i love your energy 😄

[@davebauerart]

There’s so many ways to iterate on these! It would definitely be interesting to model some flexible structures into them.

[@NinaThoren]

Loved that this video contained both the concept, design and production of the sandals but also durability testing, would love more of these videos with useful things you can 3D print!

[@jungles87]

awesome work as always! printing with TPU give me flashbacks! I was kinda of surprised the bamboo handled it that well. i've had to slow down my prints significantly to get TPU to even begin printing :)

[@MorleyKert]

Thanks! Just used the default TPU settings

[@daliasprints9798]

@@MorleyKert Based on the time that's only around 3 mm³/s. I'm not sure if the Bambu has issues with gripping the TPU that limit it, but you should be able to go considerably faster, at least 2-3x that. My TPU Benchy was something like 17 mm³/s average.

[@davey4731]

This project is so cool!!! My Brain is running wild with ways to iterate this and improve upon it.

[@GeekBoi]

I love this. The best pair of river sandles I've ever owned were alpes. The were small and lightweight with good straps. The size was great for stuffing in the back of a small whitewater playboat. They had little concave "buttons" for tread that was great at gripping wet rocks. Unfortunately Teva bought them and made several changes that really did not work well. I'd love to be able to make my own pair like that. I've not tried any flexible filaments yet.

[@rman8028]

'Size 9' he says! Small feet? I'm sitting here with Size 7 feet and glad I have that size, considering I wore corrective shoes until grade 6. Loved seeing the Costa Rica footage, since I lived in the Canal Zone (Panama) 7 years growing up. It brought back memories.

[@STILLWILLPHOTO]

Should have made some clogs, then when you have a print error you can be like, oh man, clog? Yes! Mission complete!

[@mtayseer82]

This was a nice experiment to watch. As everyone else said, up to 25% or 30% should be enough. Also, there was a video by @3dprintingnerd with Andrew Sink where they mentioned they have variable infill ratios depending on the area. Also I remember @makeanything mentioned a flexible filament made of car tires. Maybe it will be grippier?

[@davidburris120]

Congratulation on a successful first version

[@JernD]

Great work Morley! Despite not being 100% satisfied with the result, it is pretty amazing it is possible to make something like this at home. I feel a conundrum with deadlines like this, on one hand you have to "get it done" but on another you have to accept more flaws or take more risks than you otherwise might!

[@Engineezy]

Respects on full sending the hike in those sandals 😂

[@AM2PMReviews]

You learned a ton so fast. I bet you could redo this and make them way better now and basically be a pro shoe designer in a month.

[@shanomac]

Always enjoy watching your thought process. Great job Morley!

[@kauredo]

Definitely keep refining these! Excited to see the next steps

[@monsterman2043]

you make great videos man, keep it up, always joy sparking when watching you!

[@MorleyKert]

Thank you so much!

[@ultimatedude80]

God this is so cool I love all the stuff I learn about modeling and printing from your channel

[@dhp5865]

The sandals made your family happy. They worked 😄

[@Earl3]

Awesome video, Morley! I don't know that I have the guess to try making my own shoes, but if I did, I definitely don't think I'd have committed to using them as my primary (and only?) pair of shoes for a while vacation (I guess I'm assuming here...). I love your dedication to your craft!

[@viv3d]

Very cool project! When designing sandals I think the fusion 360 form workspace works better than solid modeling because it results in more natural curves.

[@onewhowatchesfires2673]

Loved the video man! Tip with the arch! Think of it like a bridge, you dont support the arch of a bridge in the middle, you support the parts on either side of the arch! Good luck in future videos~

[@cseymour97]

I think doing this in stages would be good. So have a base foundation set up at a lower infill then do the footbed as a separate piece, and maybe just get some Eva for the outsole for more grip and cushion and then you'll have a proper shoe!

[@davidjoshea4064]

I would look into a foaming TPU (Filaflex for example) compared to a regular TPU if you’re looking for comfort. Also for your sole patterning you could make the process more efficient by sketching your sole pattern on an offset plane, then using thin extrude to extrude the sketch profiles to the base of the sandal. You could also create a cutting contour to cut deeper into the sole!

[@MorleyKert]

Great ideas!

[@JoesWorkbench]

They held up really well, super successful v1.0 👍🏻🍻

[@supergiantbubbles]

This is like a masterclass in how to not make a good pair of 3d printed sandals. I'm surprised at how bad the Bambu Labs printer is at printing TPU.

[@simplybeanjelly]

Like others were saying, I definitely want to see you try these again with some refinements in the future! Could definitely make a good followup video

[@FixitFingers]

Brave man taking a prototype on holiday 😅Great design exercise and learning experience, as well as life experience mate.

This is a job for the "Mesh" modeler in Fusion 360. But respect for working out how to get organic shapes in the "Solid" modeler!

[@joelrobles9092]

[@3DJapan]

Lowering the infill will also make them more flexible.

[@danielngai]

That’s so amazing to see how you use the 3D printer

[@SICresinwrks]

This was a wild ride, loved seeing the whole creative process, but then again thats one reason why I love the videos you make😂 I wasnt very confident that they would last, so im glad I was wrong! Great video

[@whataboutbort]

you should have more subs and views this is great

[@hellothere6627]

Some advice from someone printing full shoes for years, super impressive video, brave to go full send on testing that first pair. The treads need to be super aggressive, resembling cleats for good traction 13% grid(flat) or cubic (vertical) for a soft running-shoe sole, 20% for a brick, infill multiplier x2 for a brick Top layers should be bumped up make the surface supportively stiff but the sole still soft Walls should be low, you don’t want it to be more supportive than the infill to avoid sag in the middle that splits the wall layers and discomfort Learn Forms in fusion 360, do your exact process + some new features to save a lot of effort refining some of the arch shape Print time on a non-bamboo is ~8 hours for a sole/sandle For prototyping, in vertical orientation 2 walls is all that is needed for the bottom treads to survive weeks of heavy trail use, that’s how tough TPU is.

[@ChilledTheMage]

I think we need a version 2!

[@ThunderSmell]

Great video. shoutout to cathy kert!

[@TheKingMJackson]

Dude, I would love your next video to be you putting these through trial and error and eventually perfecting them😊

[@AM2PMReviews]

Is there a way to know when a clog happens and start the print again on that layer instead of starting over?

[@Tomd8002]

I have size 16 feet (yes you read correct) and have been looking at 3D printing some sandals/shoes for a long time as I cannot get anything in my size in the UK… due to my size I’d probably have to print it in two parts and might try making a mould with it. I can then cast it using some tough resin/plastic.

[@BenWolkWeiss]

Yeah making a mold is a much better idea. Especially for the footbed of the shoe. You can use floral foam and press your foot into it evenly to get a perfect mold of your arch and foot. Then you can use that to cast a positive that can be combined with a 3d printed mold for the rest of the sole. The foam impression is basically how custom orthotics are created.

[@DifferentAverage]

Too awesome, lucky you!! I'm a size 12 so none of the models will fit on my Bambu plate unless I rotate them both diagonally and vertically. Even then it's not very practical, a 2nd bigger printer is needed lol

[@Djorak]

I'm both impressed and horrified!

[@ShrimplyAquascaping]

Next time you should try to have infill so it can compress and make it more comfortable and also reducing print time

[@3DJapan]

I think a sculpting software like 3D-Coat would be better for modeling this to get nice smooth surfaces.

[@TikTokDutch]

If you ever go to The Netherlands you should make your own clogs (wooden shoes)

[@RichardThompsonCA]

Great project! I'd recommend getting a 3d pen, you can us it to fix any problems in your print.

[@MorleyKert]

A 3D pen would’ve been perfect!

[@ВикторВълчев-р5щ]

Awesome :D In the same time, expensive sandals and failure :D I love your 3d printer. You upgraded from Prusa?

[@Cr1ptdo_real]

[@daliasprints9798]

If you want to iterate this further, maybe try foaming LW TPU.

[@Hydrosized]

I like the video, I hate the sandals on your behalf.😂

[@Noctura1138]

Your desk chair is very interesting. How comfortable is it and can you link it?

[@MorleyKert]

It's great! I added a link to the description :)

[@bigboypapaboy]

i swear tpu clogs nozzles when it is too cold? im confusesd now but i now my nozzle would clog occasionally until i got a better nozzle. the bondtech cht, has three holes that converge in one, that kind of nozzle. granted I think there comes a time where the nozzles also get worn out and that can also clog a nozzle

[@aronhidvegi]

Just use Prusa slicer instead of bamboo slicer. it should work just fine, and you can dd custom Gcode.

[@MrBenedictHeyer]

It would be so cool if you landed on a design and then built a mold cast to use a more flexible material and be able to do all kinds of colors etc in a fraction of the time. Would make for a cool video, too! Although, thinking about it, the tunnels for the straps could not be made that way...

[@Elektrotechniker]

Why have you printed the strap buckles standing up instead of laying flat on the build plate? I imagine that they will be waay more vulnerable to break under tension from the straps pulling on them 🤔

[@davey4731]

I’d be curious if deeper grooves would help for grip. My trail shoes have maybe 1/4 to 1/2 wide rectangles raised above the base of the shoe about the same to double. If they weren’t there it would be a flat surface. I find these are fantastic for grip because of this.

[@MorleyKert]

I think deeper grooves would’ve definitely helped, tighter spacing too!

[@davey4731]

@@MorleyKert fantastic video!!! Always a better day when you post. I got a pair of chacos for dirt cheap at a Nordstrom rack as my second pair and they’re the BEST!

[@ticso24]

Wonder how the result would be with foaming TPU, like varioshore. From what I’ve seen it is also possible to easily sand those print.

[@MorleyKert]

Oooo that’s a cool idea!

[@Salamattder]

I wear barefoot shoes no arch support needed, that is a spring built into your foot, you just blocked it from functioning. Also, you should have made them much thinner. Overall a great video. I love the practical application of the 3d printing and your ability in the CAD software.

[@LexxDesign3D]

The 3 day print was that with a 0.4mm nozzle? You should have installed a 0.6mm to save so much time and prevent clogging!

[@Brendan945]

Great Video! Did you consider using emboss/deboss for your tread?

Watching this type of video makes me want to get a 3D printer, but this video also reminds me why I don’t get a 3D printer… clogs, filament… ugh

[@dmon670]

Definitely could've saved that print and the material! You can modify the gcode to pick up from the layer the clog started on with every other fdm printer. Happy to help if you run into this again :)

[@gavinhicks7621]

The carbon runs on special uneditable g-code (or atleast I believe that’s what I heard from other reviews) that’s why they have their own slicer and everything. It still does use gcode and you can of course edit it but the printer has specific gcode instructions to make it run right I think. I don’t own an x1 carbon so I’m not 100% sure but I think that’s why.

[@sohanraghavendra3966]

Why don't you try post print processing like 1. Drill holes thru and thru , it removes material and increases the grip on both sides 2. Use a sander with coarse grit ? Maybe make some more gutters at the sole with an angle grinder ?

[@magnustangen6269]

Your best video to date, loved the deisng phase! im a product design student and you inspire me to get better at fusion! Maybe i missed it, but why did you use 100% infill? would be cool to see with like 90% or something with maybe the gyroid infill to get even weight distribution and support! Maybe even different infill in different places of the shoe to get more comefort and rigidity? Nonetheles, great video!

[@MorleyKert]

Thank you so much! I think I was just overly-concerned about the sandals being strong enough, and lost sight of the importance of flexibility. I should’ve printed some test pieces with different infills

[@daliasprints9798]

I'm not sure if the Bambu firmware lets you do this, but adjusting the Z offset while paused would have let you resume printing without a gap, at the cost of losing that height.

[@crono6664]

I wonder how much of difference it would have been, if he just glued an insole onto the sandals. It would let the bottoms of his feet rest on cushions and not hard plastic.

[@thesnapz54]

I'm curious of the end cost, if you're open to sharing, Morley? Feels like you did this for the experience anyway, but I'm curious how much material cost here versus these types of sandals as purchased products, which can get pretty costly. Obviously a lot of labor and lost sleep in there as well, but that seemed like a lot of raw material.

[@MorleyKert]

Each sandal took 800g of TPU, so at about $25/kg, that’s $40 USD
