3d printed differentials

[Phildirt]

I don't know man...they mention an awful lot in that ad about printing parts again after you break them lol.

Any progress? You have this up, running, and proving me wrong yet?

This was an interesting read . Can't wait for the ride to hit the track. Anxiously waiting for the video

I think we could all pretty confidently say that 12S through 5mm gear shafts would turn one or more gears, bearings, or pins into a nice pile of metal shavings. I've done some... questionable RC stuff in my time-- but even without ever venturing past 6S, I've broken a whoooooole lotta stuff.

But I still can't wrap my head around why some folks just seem dead set on turning rock crawlers into skatepark jumping, fire-breathing, bash monsters. I mean, follow your bliss and all that. But a TRX-6 with 3D printed plastic gears and 44 volts? In the industry we call that "unexploded ordnance."

I always love seeing people taking a rig in a direction I wouldn't. The TRX6s that Harley and SBG did were flat out crazy, and took the platform to a completely different level, it was cool to see, but nothing I'd likely ever do with one.

I also love someone doing something that everyone said that was impossible, like 3D printing diff gears. I would like to eat crow here, but the build that the OP has outlined don't really make that much sense, its application doesn't make sense, and his reasons for wanting 3D gears don't make sense; especially when he is planning on loading the rig down with packs, but is looking to save milligrams on differentials.

I've seen it far too many times in the 1/1 car tuning world-- people get that affection/obsession with , and spend time and money on trying to make that car something that it absolutely is not. It's generally the realization of a thought exercise. Because you can dump 6 months wages into a Civic and make it a really fast Civic, and some guy is just gonna show up with a nitrous on an old Vega he bought for $800, and blow your doors off.

Horses for courses, as they say. There are so, SO many R/Cs out there, and every last one of them can be poured full of hard earned money. A TRX-6 running on unlimited funds is never going to be as fast as something flat out built to be fast, or handle as well as something built to handle well. It might be really neat, and it might start a conversation, but it's never going to elevate beyond a curiosity.

As to the OP, this had to have been an idle-hands based episode of trollery. Nobody is putting 12S in a crawler for starters. The icing on it is looking to "save weight." Well, a motor that can handle 12S weighs 2-3 pounds, and is the size of a soda can.

^^ add to that, saving weight with 3d printed plastic gears yet, adding a temperature sensor? Then if it gets hot, add a fan or metal housing?
