My Fused Deposition Model of 6 interlocking rings.
This is the sort of thing I have carved in the past.
I was working with a friend and he has some cool machinery.
You know 3D scanners and printers etc.
So I made this...
Each ring is actually a honeycomb inside.
You can see the way the printer lays down the plastic on the rings.
Look closely for the 'grain' !!!
It still has an amazing feeling when you break away the grey sacrificial layer.
Suddenly they have noise - the plastic bangs together and it wriggles in your hand.
Bet not many people make stuff like this on their Rapid Prototyping machines!!!
