Printed fully functional Bearing in ABS , Will be uploading video shortly !
Incredible. Can’t understand how it can work smoothly! Does it require quite a bit of cleaning up? Kudos anyway!
Not much cleaning . Will be posting a video shortly
I think this is more like a “technology demo” - and a very cool one indeed 
Yes its a demo . To explain such parts can be printed .
@Richard_Papa Bearings can be made from other materials than steel. While PLA and ABS probably aren’t good for many, if any applications some of the higher temp materials or SLA compatible material may work well in some apps.
