3D printing, a possible future for bearing production?

Well, maybe... for one-off/bespoke items, but at the moment prohibitively expensive compared to conventional steel bearings which can be produced in bulk at just a few pence each!  

An exciting concept though & one worth watching as new materials are added to the 3D printing portfolio.

Cool use of bearings, in a 3D printed watch!

Bearings are often used in clock making & here's a beautiful, 3D printed example,

Of the bearings, Nicholas says:
"The ball bearings are the only movement part not made in house. At the large scale I work with it makes most sense to use ball bearings rather than traditional jewels. I experimented with printing jewels using high-strength polymers with acceptable results but found ball bearings to perform much better".
