Ring with Rolling Ball

myminifactory

For the Sinterit Lisa competition, I wanted to showcase a design that I had been eager to print, which would also demonstrate the capabilities of an SLS printer. This ring, size 8, features a ball that can freely roll around inside it. Printing jewelry with intricate moving parts is not feasible on my FDM printers due to their limited detail and inability to support complex designs like this one. The underside of balls in general tend to have poor print quality on most FDM printers I've used. Additionally, the thin features present in this design would likely be printed with fragile results on my current printers. Note: Knowing the ring size of this ring (size 8 US) allows you to calculate the ratio between it and your desired ring size, making it easy to scale the design accordingly. However, I would advise against scaling down below a size 6.5 as the features can become too delicate. I will replace the rendered image with a 3D printed one as soon as someone (hopefully me) successfully prints it on the Sinterit Lisa.
