Hi,
I had recently read this article:
Slick Trick Adds Much-Needed Shine to 3-D Printed Parts
http://www.wired.com/design/2013/03/3d-print-smoothing/
It looked like something that might be of interest, since you've done several builds involving 3d printing.
The basic idea is:
ABS-based printed parts are placed in the jar with the acetone and heated to 90 degrees Celsius on the hot plate.
Acetone has a low evaporation point, but is heavier than air so the process creates a small cloud around the model which melts the surface,
slowly smoothing it to a mirror finish. After a couple hours, the parts solidify, can be removed, and be displayed with pride.
The results are actually quite striking. As I've been interested in getting into 3d printing,
its clearly something I'd be interested in seeing more on.
I'd be willing to bet others share this opinion.
Keep up the great work,
-Cam
