3d Priinting help for bearing shaft

[jfro]

I'm trying an experiment and trying to make this part for a yaw shaft. Shaft is 12mm with a 6mm bore leaving 3mm walls which is within 3d specs for printing in Stainless which they claim is very strong.

Look for help on 2-3 fronts.


Is stainless 3d printing going to be strong enough to hang 6-8 lbs?
If I buy 12mm ID flanged bearings, does the shaft get made at 12MM or something less?
Is 2-3 weeks normal for something like this in 3d printing. This will be my first attempt.


Thanks in advance for any help or suggestions.

Anybody?

i have zero experience but people i see doing three d printing have there metal parts machined,,,, the tolerance isn't very good, at least like what a typical bearing shaft/support would need.

I was sort of wondering about the tolerances. Reading about it, I didn't get a warm fuzzy on the strength. I was wondering if the tolerances would be good enough to fit the ID of a bearing.


Any idea what something like this might cost to get a couple made? Like 2-4.

Thanks for the input.

There is no possible way you could 3D print the proper tolerances required to fit a bearing. So I guess you could 3d print it over sized and then have machined but why? Just have the part made at a local machine shop. Its a no brainer.
BTW, I spent the better part of 20 years as a certified bearing specialist in the manufacturing, repair and overhaul industry. Use good bearings! Cheers

Thanks, I've come to the same conclusion. So much out their on 3d printing when I saw they were doing stainless, I thought I'd ask. Then somewhere I read about the tolerances and had a gut feeling they were no where good enough. Always try to buy good bearings, but I have so many gadgets, I don't usually use any one thing alot, so it will not be stressed. That being said, I do like things done correctly.

Thanks for the advice.

When it comes to these small deep groove ball bearings the more expensive ones for the most part don't take more load. It's at speeds where they prove their worth. So a rule of thumb is low speed < 1000 rpm save money buy chinese. For high speed applications get the good ones. Japanese, Sweden, Germany etc. Cheers.
