You could do a silicone mold of the resin printed tire, and then cast it with flexible polyurethane. That would probably be the most wear resistant part that hobbyists can make themselves.
plus you can make a tire in a few minutes instead of waiting for it to print.
Plus the ability to make composites:
Add a fibre core, although this would make more sense for cast timing belts.
Or mix in fibres with desirable properties.
Plus the option for double-shot molding:
For instance 98A for the inner rim, 92A for the tread.
Or simply cast the tire around the hub.
@@ronnetgrazer362 Okay let's not get crazy.
@@graealex I say, let's!
Absolute overkill for one-offs, sure, and for very demanding applications maybe you should be looking at professionally (mass-)produced parts, but neither of us thinks it's outside the scope of the determined hobbyist to cast some custom wheel sets for, say, a low volume kit campaign.
Relatively speaking, my suggestions don't add a lot of complexity if you're already taking the home-casting route.
@@ronnetgrazer362 The guys at "Easy Composites Ltd" here at TH-cam already do a pretty good job of that.
Would be neat to see a store bought RC tire with same size and tread compared with tpu. Good video. Thanks.
This also shows how microplastics are actually created. By friction.
It's one of the ways and also tire emissions are also often overlooked when talking about vehicle emissions and I've always wondered why.
@@k20nutz That haven't been any scientific study that prooved that microplastic that tire pollution is harmful for the health. The have been multiple studies that prooved that diesel and petrol exhaust cause cancer, strokes, depression, alzhaimer and Parkinson disease and inteligence reduction..
@@velikdole9712 That doesn't really have anything to do with what I said because regardless of harm (I don't believe your stated lack of harm, but carrying on) it's still an emission.
@@k20nutz Afcourse it have to do with what you said. Yes, it is an emission which is MUCH MUCH less harmful than diesel and petrol exhaust. And that is my whole point. And tire particle emission is almost the same or the same for electric and for diesel or petrol car (Tesla model 3 weight actually LESS than comparable petrol BMW M3).
@@k20nutz So to answer your previous question why the tire emissions are often overlooked? Because they are MUCH MUCH less harmful for the health. That's it. It is totally normal to focus on much mure harmful things firs (like diesel and petrol exhaust).
Tom Scott recently posted a similar video but related to asphalt wear but the machine used there could serve as inspiration for improvements
Inspired by one of RCLifeOn's videos I 3D printed my own 130mm tires for my electric longboard. I've ridden it about 500 miles without needing replacements.
I find it hard to believe that TPU can be that durable.
@@internettoughguy are you familiar with printing tpu?
@@trevorcrain9620 Never tried printing it.
Did you print them solid? Or thick walls with infill? Can you share more details, do they absorb vibrations, do they cause vibrations? im interested in doing the same.
@@viko207 I don't remember the exact infill % but didint print them solid. I think it was around 75% or a bit over and I think it was around 5 outer perimeters? The more outer perimeters you have the longer the wheel will last. I can't really say about the vibrations but They roll over everything on the road and the ride overall is way better. I've ridden without them maybe twice.
i believe the resin got more wear because it was the leading tire removing objects for the rear tire. a better test would be to do a 360 clockwise then have it run a 360 anti clockwise etc etc
I see one problem, when you put it in dirty or rocky surface the first tire clears out the surface or makes it smoother for the other tire to go on. For a solution you can extend one the placement for one of the tires.
not entirely sure why he went with testing both at the same time.
it would solve so many problems had he tested them one at a time
although the results would be indistinguishable anyway
@@GeorgeTsiros he probably did that because he wanted them to be tested on the same weather
😑
I remember when I was in High School, we got the great idea to build a Full Size Big Wheel.
I learned a lot during that particular building and explored the basics of how different it is compared to typical manufacturing.
One thing that I will say is that TPU tires do work relatively well, but you absolutely need to print with high infill, and you almost have to create brand new designs for the tires themselves. We tested ours with standard bicycle tubes, was an 18" wheel, lasted around 40 miles before it blew out. So, it is possible
in general, TPU is by far my favorite material. Very resistant and durable.
Mine too and it prints beautifully on my crappy anet a8, actually better than pla. I don't understand this but a new printer just so I can print tpu, you can print in tpu ridiculously easily. I printed tires with it and they're awesome! What awesome things have you printed with tpu??
Edit: his printer was a Bowden extruder, my pet hate for extrusion for many reasons...
Nice idea. Your test methods could have been sightly better though.
- Store bought TPU wheel added to the comparison as the control
- The wheels were independent of each other. The snapped wheel hub happened for a reason. It clearly shows that the motor speeds were different and maybe some misalignment with the mounting. So one wheel was probably pushing and the other was dragging.
I'd like to see a part 2 where your testing methods are better and with the control. :)
It would have been interesting to test PLA+ just for the heck of it, simply due to the fact that's probably the most common filament sold. Not so much about comparing it to TPU, more about if it was 'good enough'. TPU really hung in there, even the resin wasn't to shabby.
Kiss braking goodbye... PLA+ tires would be like driving on ice. Dafok m8?!? Of course you need TPU. Heck, even TPE with 83A durometer would be more appropriate. if it was just durability everyone would drive on stainless steel tires HAHA
Nicely done. Intrigued me that it wore the groove into the gravel. I thought it would be too light weight for that. Perhaps it’s heavier than I thought.
Love to see you back man
You can also resin print flexible materials.
i been using tpu filament in a bowden extruder with very little issues.
once in a great while the filament pops out of the extruder stepper gears. but that can be solved with a better stepper driver housing.
Thinking about the infill density and how it could be used to affect spongy response with RC cars. Way cool!!
Like a tweel?
My first printer was also a one up! What a mess haha, im still using some of those steppers though. I'm glad printers have progressed so much since then
Thanks for sharing.
Couple points:
Should of angled the tires in the direction of travel. (front tire driving out and rear driving in, constant slip angle, but in opposite directions)
One of the motors probably had more speed, thus driving harder and more wear.
Very informative thanks 😊
Would you mind putting the link to the flexible resin you used?
A load would have been good to add to see weighted ware unless you plan on a base of only a few pounds.
My first 3D printer was the QUBD Two-Up. I had completely forgotten about it.
You should have a little resistance also, like something dragging behind . And only test one type at the time, that would be really interesting! Thanks for a good video!
I'm curious if/how the performance of the TPU tire would change by annealing it
You should try using flexpla. Its a bit stiffer than tpu but you can print it using normal pla settings and speed.
What is the shore hardness of the TPU you used here?
Nice video
How does the tpu tyres work grip wise 🤔
How much Siraya Tenacious got hardened due sunlight? Ive heard its not staying flexible when further curing by sun
at 2:00 i knew immediately you would be moving the clips to the front😂 i've made that mistake too many times lol
Thought exactly the same 😂
2:00 Yes it's crazy how far they've come. I even heard there are printers out there which don't use this shitty mechanism to mount the build plate. And if it isn't clear - one big problem here is inconsistent heat transfer due to pressure only being applied at the edges.
This is barely an issue, even heating on the bed doesn't effect the print in any noticable way.
@@lobsterbark Of course it is an issue, at least for high-performance materials. Obviously it doesn't matter with PLA.
@@graealex If you are printing something that sensitive you should be using a heated chamber, using either a core xy or a delta, depending on build volume. Even nylon isn't that sensitive though, you would be doing something very special to need that.
@@lobsterbark What kind of rubbish are you trying to tell here? Uneven heating means uneven shrinking, and that will already affect ABS prints. And a heated chamber reduces the gradients, but for most practical purposes, the heated bed will still be at a higher temperature.
And before you write more rubbish, maybe just Google for people having problems from unevenly heated beds. Because there are plenty.
@@graealex ABS isn't commonly used for printing anymore because it's so sensitive to that kind of stuff with no benefits vs other now common materials. It's one of the few materials where that actually does matter.
I've been building and using 3d printers for almost a decade now, this has been my personal experience. Uneven bed heating really doesn't matter with any common material.
nice test. I don't know if the battery was enough load for the tires, but that's one thing you might improve for next time
That extrusion is reasonably heavy.
It was a great test video, and for a crawler style RC it would be enough, but for most RC cars that go a lot faster, grip is more important, so I'm more interested in the amount of grip these tires can get. Also, I'd like to know how much harder the resin tire got, because I have a similar resin and they get quite hard (although not as hard as standard resins), so I haven't tried printing a tire out of it
Zero grip lol
The resin printed tire wearing out I think mean its softer, if that is true could it have more grip. I'm thinking the difference between soft grippy racing tires and harder normal tires. while they wear out fast could mean they are getting more traction just some thing to think about maybe test.
Add a solar panel on it so it continues running!
the saw box cutter hahaha
What resin printer are you using?
What if the resin had more wear because of better grip?
Hew, what screwdrivers do they use? 3:22 specifically, the metal handled ones.
you should try printing the wheels with different grain angles! side of the wheel face down, the gripping side of the wheel down, then at a 45 angle? i wonder how large the differences in wheel lifetime would be!
What is work plane of the 3d printer?
the the test to be done with pressure or with weight that you press to see the real wear
I made TPU sand paddles for my Rustler. Use them at 65mph. They are holding up just fine, all things considered.
I would like to see the most important test for RC cars specifically: high RPM and ballooning. how long till the tire tears or shreds compared to a regular RC tire.
Did you rotate and balance them every 3 hours of use ?
i need download link of that tires
do you have an estimate for the _overall cost_ for a set of 4 of those not-completely-stiff tires?
like
if i asked you how much would you want for a set of 4, how much would it cost you over all (material, electricity, time, effort) ?
the stiff ones would be kinda better for offroad
the rubbery ones would _probably_ be better for onroad RCCs
The cost of the materials the power is very small. Maybe $3.50 per tire at most. But the cost to custom design the parts is laor intensive and people typically can charge $100 per hour.
The best wheel design uses a metal hub. I like to use steel about 20 mm diameter with threads for set screw. Then over then goes a PLA/PET wheel and then a TPU "tire" and the parts are glued together. Yes you NEED the steel hub as it ti the hole in the wheel where the motor shaft goes that usually fails over time.
I print a lot of TPU on my stock ender 3 with it's bowden extruder. Never had a failed TPU print. Nice test.
What is this wizardry. I have ender 3 pro.. then again I’ve never tried tpu lol
Same here, however I did change the bowden tube to tighter tolerance Capricorn and did some of the mods to the feed assembly to make it easier. All easy stuff and well worth it.
Surely the front one would have gotten more wear did you swap them during the testing?
You didn't mention the durometer of either material used in the tires. All other things being constant, the softer the durometer, the better grip you will have with the tire, but the more quickly it will wear. I'm also not seeing any links to the materials used.
you basically built a road materials testing machine. nice! also I have had great results printing tpu on my cr10
I'm just glad you spell tires correctly I'm not sure how words like that and color get mixed up in English
Nice video! In this configuration one wheel is pushing, one is pulling. The stress distribution is different in both cases - the pushing wheel is pressed stronger against the ground. Have you considered alternating the driving direction?
Also the speed between the 2 motors may not be exactly the same, causing slip on the wheels which also may not be distributed equaly between the wheels
this design of printer seems perfect for a belt printer
You know this guy's got some badass 3D printed guns
At the end when you say it has a dire t drive so it can print any filament. You should have said. It can print any stiffness of filament.
Hi! What's the audio started ~ 1:15 ? 🙏
TL smoothers were made specifically for TI's DRV chips. I don't understand how Allegro drivers have that problem. None of my Allegro-based boards exhibited the salmon skin problem. But if you have that problem and TL smoothers fix it, I guess I can't argue with it.
@ 5:30 I can only think this would be awesome as Zen Garden Sand machine.
Alot more engineering in that but hey you'll have a saleable product and millions of views.. like a Sisyphus but for the garden..
Fun video. I love guessing which one will win!
People walkin through your yard are gonna think this is something out of signs looking at those circles
No one drives their RC car that slow Test are inconclusive. Also what TPU shore hardness did you test in?
Good video👍🤝🤝🤝
It’s not difficult to print TPU. You just have to slow it down and minimize/no retractions on Bowden tube
@@matthewbrown1617 when I mean slow, its like 40mm/s. I have a FLSUN SR and ender3v2 and both are bowden. I can print it. its easier with direct drive for sure.
It's crazy how far printers have come....then proceeds to put bed on with paper clips. Hahaha
That's the stuff
Won my sub in 15 seconds, and the rest of the video didn't disappoint
It could be interesting to do the same test using rubber-like resins like the F69 from Resione...
Nice one - but what hardness was this TPU?
Most TPU is quite hard, he's probably using something 90-95A
@@jaro6985 I was going to say the same. Unless specifically specified, I just assume 95A.
that Kywoo sounds like if Daewoo was found by Mr. Ky :D :D
Problem is I would say 97. % of the time I drive xmax the tires are spinning not just slow roll
Couldn't you have used a dremmel to test the durability of the tires?
i printed 4 98a tpu tirells for electric skateboard from thigiverse in order to increase wheel diameter from 90mm to 105mm，they worked fined for 100+kilometers，they take about 1 week to print on ender 3 with 50% speed，no infill all wall lines，100kms later only outer layers worn slightly（about 5 layers each 0.16mm）
How is the grip? Can probably get away with
They work for my lawnmower. Im in south texas though, so there are things to deal with of your going to leave it outside.
I was thinking of a riding mower and like whoa, this guy has way too much money and time to print that...
I thought this was rctestflight videos until I heard your voice 😂
Crop circles mystery solved
Should of the switched the wheels to see if that made any difference
_this_ is how the aliens made corn circles 😄
It could be one motor was spinning a tad faster than the other one, making the one with the slower motor being dragged along more.
Better test would be both driven by the same motor.
Thru look like tetrix max all terrain tires for robotics
Rokenbok! That is all, good day.
Hello. The result of the test is not right and not false. You must repeat the test, but you must chance the position from the wheels. Only chance the wheels not the motors. motor 1 ist a little bit faster as the other. The lower motor brake the wheel and this is not good. Or you build a testversion with a single drive motor an transmition on boths wheels.
Crop circle ⭕️ generation machine.
i had one of those original printers, i never got it to print correctly. yikes was that a piece of crap.
all you tested was abrasion resistance, not grip, damping characteristics and such.
This test is okay but doesn’t the first one take a beating carving the path ?
👍👍
Alt title: Toby McGuire gets into 3D printers, makes tires to abuse.
If you decide to make a offset ladder of wear in new treads as the old treads wear away the only thing I ask for my ideal is to name the design: monkey toe.😁thanks
instead of solid wheels, make flexible flap wheels
Glad that fat tire wasn’t left out of the list
It’s arguably the most important
3d print a box opener
80% of tpu can be printed on bowden tube printers no-problem
M2 screws "sheared off"???
I highly doubt that.
I hope this project wasn't... TIRING :d
:D
it needs weight for proper testing with that setup though
The resin is much better at turning into micro plastics.
Keep it going for like a year or something
Get a flsun Q5 once you go delta you don't go back!
"It's amazing how far 3d printers have come."
Proceeds to attach the build plate sheet with binder clamps. Lmao.
Well, a big point in manufacturing is using standard parts on designed objects
@5:23 -- it looks like for the bulk of the testing, the resin wheel was in the front -- it seems kind of obvious that in this configuration, it would show more wear -- I feel like the testing is invalidated by this. (Not trying to be rude or mean -- I just legitimately feel like the testing was not scientific; or if it was, then the details about controlling for this were not adequately presented. -- This doesn't mean the conclusion of the resin wheels being less wear resistant is an incorrect conclusion -- it just means that this is not good proof of that conclusion.)
I also would avoid using different diameters for the test, and would avoid testing in the same spot sequentially... as those would also invalidate the test. -- Instead it would be a more controlled experiment if you built two devices and placed them in slightly different locations, under the exact same conditions (controlling for weather, sunlight exposure, terrain, etc).
I think alternately, you could prove me wrong by one of the following methods:
1.) Print new wheels, and do the exact same setup with the opposite setup and showing the same results (i.e. the orange wheel is in the front for the entire time, and still shows less wear) [of course in a new, non-pre-worn locations, with no swaps or direction changes].
2.) Used the same wheel for front and back and showing that they wore evenly [of course in a new, non-pre-worn locations, with no swaps or direction changes; one wheel is in front 100% of the time and either wore less or evenly with the back wheel].
