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.

Would be neat to see a store bought RC tire with same size and tread compared with tpu. Good video. Thanks.

Tom Scott recently posted a similar video but related to asphalt wear but the machine used there could serve as inspiration for improvements

This also shows how microplastics are actually created. By friction.

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

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 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

in general, TPU is by far my favorite material. Very resistant and durable.

[Shocker]

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. :)

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

[Visiorary]

Thinking about the infill density and how it could be used to affect spongy response with RC cars. Way cool!!

[Mark-hbzf]

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.

Would you mind putting the link to the flexible resin you used?

[partsdave]

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.

[thetimo]

My first 3D printer was the QUBD Two-Up. I had completely forgotten about it.

[HenrikOlander]

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!

[KilroggWOW]

A load would have been good to add to see weighted ware unless you plan on a base of only a few pounds.

[DPrinterAcademy]

at 2:00 i knew immediately you would be moving the clips to the front😂 i've made that mistake too many times lol

[jbergene]

You can also resin print flexible materials.

[Ozzy]

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.
