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

Cool, interested to see how it works.. can you take time lapse vids of it building them?

the printer only works in an inert enviroment so its actually in an airtight case, im not sure how a camera would cope. also, i think the laser point is so bright it would damage the camera sensor

How do you know whether it'll be strong enough?

Im an FEA engineer, so thats my first port of call. unfortunately, i dont have enough time to do it properlly, so its gunna have a lot of guessing. im probably just going to make a part that weighs a specific amount and make sure it doesnt have any stress intensities.

also what are the approximate costs of this endeavour?

printing stuff like this costs mad dollar. fortunately, im not paying ;)
