The original STL is too big, So I have reduced the facet. This is to test that the bearing is printable, but there will be support structure needed. It takes us 1 hour and 11 minutes to print, and only another 3 minutes to remove the support structure. The support is very easy to remove. As long as the support structure is cleaned up, it will be slippery enough. (edited on Sep6)
The model we printed is 0.3mm deposition layer setting, object fill density is loose. There is less support between the balls when i change the support angle, I choose 30 degree. Before printing the bearing, remember to paint a new layer adhesive on the platform. Then remove the support, all the balls are connected, so a carving knife will be used to to separate them. We will upload a video that the bearing was printed to our website soon.
