Quickbit: 3D Printed Bearings!

There are a few 3d printed bearing designs floating around online, I test two I found on thingiverse that require no extra parts and should work right off the bed. So are there any gotchas to printing these? How well do they work? Does the filament used affect them? Watch to find out!
The designs I demo in this video and a few others can be downloaded here (I didn't design them, all credit goes to original authors):

Accidentally saw my bearings as I was scrolling through youtube lol 🤯
They work as if they are lubricated once you follow the instructions and roll them out on a carpet for a minute because that removes the imperfections of the print under the pressure of your hand. But not only do they roll good, they also have alot of horizontal strength vs the conical design because these were designed with 3d printers in mind :)

Thanks for sharing your design with the internet! With the right application these print in place bearings are awesome to be able to print off and have in service quicker than running to the hardware store or buying online.

I've been trying to successfully print 608 bearings for awhile now. I'll have to try these designs for sure. I just need them for a spool roller and, I really don't feel the need to buy bearings for something so simple. I never thought to try a raft. I'm going to try that and see what happens.

[@fennecfox7137]

Friendly tip: WD40 is not a lubricant! It's a solvent. A proper grease or oil will help a lot more ;)

[@sjm4306]

Franlab did a recent video on it. It's originally actually neither a lubricant nor a solvent but a water displacer (hence the wd) meant to prevent ice forming/sticking on space rockets!

@@sjm4306 Huh interesting. The more you know :O

[@michal_king478]

these are deffinitely useful I always find cool stuff to print but it always requires a few bearings of different sizes. Often ball bearings arent even really needed there (stuff like a small jet engine model etc) as its not something where the bearings have to either support a big load or turn a lot or quickly.

[@bonovoxel7527]

BB bullets tend to disintegrate. Better print your own rollers (not balls). Built up designs are usually better than the print-in-place ones. All given and tried and printed ofc and considered, the only place I can mind where I would use a 3d printed bearing is the filament spool roller.
But I bought 20 std rollerblade bearings at 8.99 on A and printed them a TPU collar just for the sake of have them rolling and not sliding.
No Idk where i'll be using the 16 left ones, yet.

[@alerey4363]

Although interesting from a maker pov, these has very little use because the constant friction and load in a real world mechanism (toy, robotic arm, etc) would rapidly break/loosen the parts; I guess that even nylon wont survive more than a few months of constant rotation in an everyday application

[@sjm4306]

Yeah not reliable for either long term or load bearing applications. But for something trivial that doesnt rotate much or bear much weight like a filament feeder it's probably ok. Pretty niche in real world use but still an interesting look at what 3d printers can do.

[@NrOneSimpsons]

very intresting! would love to see more videos using the 3d printer :D

[@sergeiglimisRV]

Have to print them 0.1 mm layer height

[@TheJunky228]

those were surprisingly better than I expected
edit--back in highschool, I printed off a doorstop that would be attached to the door face and hinge down to press into the floor and hold the door in place. It was simple, but it was the first thing a student had designed that required no assembly but still had moving parts, the teacher was pretty proud of it lol. Our school's printer could print two materials at once; a filler, and the actual material. Then the part would get submerged in this tank to melt away the filler. Is that the sort of thing you had to do, or did your printer just print these as-is and was still able to keep them from sticking together?

[@sjm4306]

This was surprisingly able to be printed as-is. I do wish my printer could do multimaterial though as I can think of a ton of things that could benefit from that

[@coffeelatte141]

As always cool stuffs!

[@brandonpenafielvelez7374]

Did these bearings print ready for use? Or did you need to assemble them beforehand

[@sjm4306]

It's print in place, meaning it's fully assembled already. The only thing is you do still need to work the bearing to break away little bits of fused plastic between parts and wear them a bit to make them spin freely. A little lubrication also helps.

Hello,
May I ask which 3D printer you used for this?

[@sjm4306]

Creality Ender 3 pro

Nice video!
Can you share the stl links, please?

[@sjm4306]

Oops forgot to include the links, the video description has been updated to include a few different designs including the ones in this video.

But why ? You can buy them in far superior quality and for a fairly cheap price, what´s the point ?

[@sjm4306]

I don't actually use these for practical stuff, they are more like fidget toys that sit on my desk at work.
