3D printing a set of hubs (or what ever I think of)

If you have the carbon axle as shown then at least one cup will have to come out of it every time you want to change the bearings

yup, pretty much, but the new hope hubs use the same system.

It's a sintering process this, isn't it? How does it affect the strength of the final material? Let's say ya boggo standard pressed mild steel for a flange is something like 500MPa in tension, what would this stuff come out like?

this is a really good question. in all honesty, i have no idea. i was chatting to our printing expert the other day, and he claimed the in plane material properties of sintered alloy, could actually surpass that of non-sintered alternatives. He explained why, but there were alot of words i didnt recognize.

really i should use reliable sources when choosing material properties to model with, but im going wiht this site for speed

the simulations are on, heres the mesh:

theres going to be two flavors of simulation, first will be tensioning the spokes to 200kg, just to see how it reacts. the second will be taught spokes, and then a single spoke will be pulled until failure. this is quite unusual because its not realistic, however it is basically the worst case scenario, which is what im interested in.

these computations are pretty heavy so im running it through a small cluster, however, it still looks like itll at least take 10 hours.

when the results do come in, i can have a look at areas that are highly stressed, and those that arent. then material will be stripped away accordingly. unfortunately, this thing is currently HEAVY. the stainless steel parts alone are 180g, and its a front hub!
