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 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.
@@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.

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.
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 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
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
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
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.
@@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.
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.
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
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.
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!
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
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!
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.
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.
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
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.
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.
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.
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.
@@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.
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）
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.
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.
Can you print solid rubber tires for electric bicycles? 20 by 4.0 and 26 by 4.0, specifically for the Annika A8 pro.

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].
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.

I didn’t mention it in the video so it seems like a lot of people didn’t catch it but I switched the wheels order when I replaced the hub. It was about halfway through the testing.
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
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.
Well done
