3d printed “foams.” What do y’all think?

[BarnFabRC]

So I picked up a set of 3d printed inserts from one of the guys last weekend. They’re pretty neat. The idea behind them is to give the tires an open cell feel when accelerating and landing but a more firm closed cell feel in the corners. There’s a couple guys that are running them in the rear and are happy with them. I got a full set for the 4wd buggy. It’s interesting how they change the profile of the tires.

The pic above is the rears. JConcepts double Dee’s. Foam in the left tire and the 3d print in the right. I’m pretty sure I’m going to go with the 3d printed ones in the back. I like how flat the tread is. More pins in the dirt at the same time.

Now for the fronts… I screwed up and grabbed 2wd front tires at the shop (I swear I saw 4wd on the package) with the foams I don’t really see that much of an issue running them on 4wd wheels. But with the inserts it really flattens them out. I’m not sure what I should do… run the 2wds with the foams or buy another set of 4wds and run the inserts.

Maybe I’ll just get some 4wd ones, I’m planning to resurrect the RB10 at some point for Pit Stop. Rear motors are king on that track. I can throw the 2wd ones on that.

What do you guys think?

Wanna see how those do. Usually see 3d printed foams for the crawlers / trail trucks.

So those are for bead-lock, or SCT wheels?

Can't imagine stretching them over a "normal" wheel.

They’re standard 2.2” buggy race wheels. Wasn’t too bad. The hardest part was actually getting the beads to sit nicely. But once I glue them they will be SOLID. The “squeeze test” has a nice squishy feel in the middle of the tread but it gets progressively stiffer as you get to the outer edges of the tread.

I use them in my crawlers and love them, I like them better than standard foam. Let us know how they do once you give them a work out.

Hmmm. I'd like to try some in my cars.

do you know if it’s possible to buy those?

He’s on the “Pit Stop Hobbies racer page” on FB if you scroll down a little his post is there from late last week. I paid him $20 for the set. I’m totally forgetting his name right now. Nice dude.

Thank you!!!

Watching this thread to see how they work out for you. Know both the military and auto industry are working up prototype airless wheel/tire combos. These look very much similar. -AC

I've printed and used a few sets in my crawlers. I've definitely thought about designing a set for sct tires/wheels.
