Need for New Hobby Leads to Stone Marbles

[Tom Lange] said he was looking for a new hobby when he saw a marble made out of stone and wondered what goes into making one for himself. Fast forward three years and he set up shop at the Madison Mini Maker Faire to show off the tools he built and the fascinating glossy orbs he’s produced. Read on to see the awesome process he uses to turn a hunk of stone into a perfect marble.

More acetone-vapor polishing experiments

If you’re thinking of trying the acetone-vapor polishing process to smooth your 3D printed objects you simply must check out [Christopher’s] experiments with the process. He found out about the process from our feature a few days ago¬†and decided to perform a series of experiments on different printed models.

The results were mixed. He performed the process in much the same way as the original offering. The skull seen above does a nice job of demonstrating what can be achieved with the process. There is a smooth glossy finish and [Christopher] thinks there is no loss of detail. But one of the three models he tested wasn’t really affected by the vapor. He thinks it became a bit shinier, but not nearly as much as the skull even after sending it through the process twice. We’d love to hear some discussion as to why.

There is about eight minutes of video to go along with the project post. You’ll find it after the jump.
