- Today I designed a print in place ball bearing that uses minimal supports. The design itself does not have any supports, the supports that CURA provided were sufficient. If you like this video, stay tuned as this design will come in play again for one of my near future projects! Subscribe!

Adding grease to the bearings should reduce friction, giving you more spin time and reducing energy consumption. Awesome vid!
This is what I think exactly in my head when I think about a 3-D printed bearing
Yeah same. And when I think of a 3d printer I usually think about a 3d printer too.
Thank you very much i have designed with this the gearing for my hand crank generator
Thanks man! Your video inspired me to try it for myself. I tried several sizes and the rolling resistance if far lower than I would have expected before I watched this video. The bearings tend to bunch up a little, but they can take more pressure than you'd expect. They make a discomforting crunching sound when you load them up heavily. You might want to use a higher filling rate, so they are completely filled up.
I used FreeCAD and I made it parametric, so I just have to enter an inner and outer diameter and it gives me a bearing (within limits). Quite a fun project.
Thanks for watching! I may be revisiting the ball bearing to see if I can improve it. I did put this on Thingiverse if you want to check out the model. My next video will also show a use of this bearing, as I made an object with wheels.
Hi sor can you show me your parameter setting in prusa or cura to print ball bearing?
Thank You. I needed to print a few bearings that had the elements printed in place for visual use only. This will work well.
Do you need the file? I didn’t post it anywhere, but I definitely could.
@@PrintPractical i would like the file pls
Didn't share file?
@@3dgiftz no
😕
That's really cool! I wonder about 3D-printed roller bearings?
I'm trying to do something similar but having massive issues. For some reason I keep getting layer offset which I assume has something to do with how it prints the bearings. That or the bearings pop out during printing. My design isn't super similar to yours, but did you encounter similar issues?
how will you fix this bearing to an assembly as well as the shaft
Good video. This design is missing the ball retainer/cage. Without this cage, the ball spacing is not uniform making the bearing concentricity change as it rotates. It also allows the balls to rub each other while turning, creating unnecessary wear and friction. I think you could design a snap in cage that would solve this problem.
Good point, I had to look more in-depth into ball bearings, as I didn’t know about that. I’ll have to add something in to fix this.
@@PrintPractical Looking forward to that. In my attempt the ball bearings are somewhat rhombus or diamond shaped. The bearing rolls quite well despite this because the unevenness of the bearings is offset by eachother. I wonder how low you could make the rolling resistance when the position those bearings is fixed.
Try to print it with a small nozle with small leyer hight
@@JasonRobards2 when you export a stl file from a cad program, it essentially has to convert those high precision mathematical curves into triangles. That in turn means that the curve gets converted into a series of points, connected by straight lines. There should be a setting for resolution that affects how many of those points will be created.
Now the diamond shape could come from printer settings, but it could also come from the issue I mentioned above, but I don’t know your specific workflow.
Hi sir i would like to know your parameter printing in software slicer to slice this file, because i have some problem to get smooth result for this object
Can we print the inbuilt models available in solidworks
Print in place is awesome. Im assuming you can scale this up however large you want? Gonna print this and give it a try. Liked and subbed.
Awesome thanks, I only tried it at its current size. I can try to scale it differently this weekend, but this size has worked for a few of my projects. My next video involves a project which uses this bearing and a print in place ball joint I designed.
Thanks for the sub!
Do you have any specific slicer settings? My print is failing on standard 0.4mm nozzle
Sick. Hoping to try this out. Modify a little on Onshape per my needed diameter
Ugh I can never get the edit options i need after importing. I guess i'll do it from scratch with your vid and stl to reference
thank you
wow cool plastic bearings....
Thanks for watching!
is there a way to make the bearing bigger and wider I need it for my ender 3 filament holder so it can spin better.
How infill density did you use?
Could I try this bearing out? The files I have been using are giving me issues
Hey Billy, thanks for watching! I just dropped the file on Thingiverse, feel free to give it a try. I've only printed it at 100% scale, so depending on your use, it may or may not work if scaled up/down. www.thingiverse.com/thing:5027112
Try to print it with a 0.2 nozzle or evean a 0.1 nozzle i tried to print a print in place bearing with a 0.2 nozle layer hight o.08 it was very nice an with minimal friction and also try to make it like 608 dimensions
Have you ever used a 3d scanner? If so Do they work well?
I haven’t, I draw all of my models. The “project” I keep hinting at is actually a 3D printed turn table to show off my prints, which I could probably use to 3D scan. I’ll have to look into it after I finish that project.
Polycam works fine. Not for mechanical stuff. You can just use your phone to scan stuff via video... Good for making dioramas
What software is that?
Looking to upgrade from TinkerCad lol
Thanks for watching! In this video, I’m using Inventor. I’ve recently started to switch to Fusion, as it offers some convenient features that Inventor lacks. Also, Inventor requires a license and is pretty expensive, it’s targeted toward the professional industry. I’d give Fusion360 a try.
Nice, how much filament was needed for the second one?
Probably about it’s weight in filament
💡 Suggestion: a completely 3D printed fidget spinner with this 3D printed bearing design integrated into it. 😉
Interesting.. I’ll have to see how this bearing scales down. With the current size, that’d be a huge fidget spinner haha!
Thanks for watching!
@@PrintPractical I mean, the body of the fidget spinner will be basically the outer "ring" of this bearing design. Also, it needs two separate pieces which snap together trough the centre ring of the bearing, where the fidget spinner is held, you know. 😉
What is your printing setting and material
Material: PLA
Extrude temp: 210
Bed temp: 60
Print speed: 60mm/s
@@PrintPractical how about your support material?
i am going to mass produce 3d printed fidget spinner;s
Cool that you did it but once again 3d printing has a ton of limitations and these look awful compared to any cheap and regularly avaiable ball bearing.
Yeah I mean you can’t compare 3D printed pieces like this to actual metal bearings. It’s just impressive to see that you can make things like this that are print in place.
I have used these bearings in a few projects, just to keep them 100% 3D printed. I like showing that these machines are capable of making some impressive things.
Thanks for watching !
И это убожество ты называешь подшипником?
Почему бы вам не назвать это подшипником?
