What printed parts are the most likely to fail? What parts have you broken? I am thinking about making non-printed versions of some of the parts. Right now I was looking at the wishbones and I could water-jet out blanks that have the rough shape. They would need the holes drilled and the outside edges rounded. But if I were to do that, would anyone else want some blanks? Or even finished versions? I could also anodize them. Just thinking outside the box.
In a brushless setup, the printed diff’s are the first on my list. I couldn’t get them to last for a reasonable amount of time. Second, wishbones, but you can also print them in polycarbonate.
@Joshua_Updyke Well, i´m sure i´ve broken most parts at one point or another… 
But i have broken a few wishbones before i printed them in Nylon. http://youtu.be/Ope7-yct-v8
I´ve broken i shocktower in a crash: http://youtu.be/v21RJj0NgMw
Other than that i´ve broken alot of central driveshafts because of obvious reasons.
Diffs are also subject to fail for different reasons. I will be doing a better updated design of the diffs but i have some other things on the car that needs to be adressed first.
It will be cool to see your alu parts. check earlier posts in this group, there was someone who did alu wishbones, don´t rememeber who though.
This is really helpful guys. From looking at the design and just generally how the parts work those were all parts that I thought were taking the most foces. The differential housing is pretty complex and what little I have looked at it would require a lot more effort to machine. That is one of the great things about 3d printing.
The shock towers would also be good parts to waterjet. The constant thickness makes them idea. They are also very close to the same thickness as the wishbones which means I could cut them out at the same time. Then toss them in a vibratory tumbler to round out the sharp edge and drill and tap the holes.
I will try and find the older post about aluminum wishbones.
Thanks,
Josh

Did you ever manage to break anything on the main chassis? (bottom/top and side plates)
@Emile_Wim Hmm, the link didn´t work, here´s a picture from one of my first builds breaking. The topdeck failed causing the main chassie plate to brake. https://dl.dropboxusercontent.com/u/6748864/IMG_20130418_190137.jpg
Broke my first bumper today, but the rest of the car did survive. https://dl.dropboxusercontent.com/u/96359783/2014-03-23%2001.27.45.jpg Rocks are hard on plastics.
