I think it means you have to bleed on 'em!
So - that said - had to give it a try. I decided not to muck about using my headbed, I used an electric hotplate, and hooked my IR thermometer up to it. Note to self - 120c is *not* 11 on the dial. It's more like 1!
My nephew loves the Octopus in a bucket, and I happened to have one laying around. It was printed on Ugly at .2mm layer in really cheap Chinese red ABS that I actually quite like.
I used the same method described in the video - used coathanger wire to make a holder with a tinfoil base - about the only thing I did different was to make a hook in the coathanger wire so I could suspend it off the side and keep it above the acetone that way.
As I was heating, I didn't really see the meniscus creep up the side of the jar, but you do see condensation of the acetone as boils off and the vapor climbs higher.
I popped the part in, and it's amazing how fast it starts to dissolve - literally by the time I had the hanger hooked on the side of the jar and was paying attention to Octo, he was already shiney and starting to get smooth. I got paranoid about 1.5 minutes in, and pulled him out - he looked damned good to me!
Next experiment will be a 20x20 test cube, and measure it before and after. I'm also thinking it's going to create a stronger part, so I'll probably print a lever or two and try some shear tests.
All in all? +10 on the Fun Scale - other than paying attention to the heat on the hotplate, nothing to "do", and I didn't even notice as much in the way of fumes as when I'm cleaning my boro. I think I'll have to go by the pound store and see if they have some cheap pyrex bowls - the only limitation to the method is the width of the bell jar I was using....
I'm not sure that it would be something I'd do for 90% of the parts I print in ABS, but it makes me think more about some of the parts I print in Faberdashery PLA at insane prices just because of the vibrant colors - if the color holds, this red ABS looks much better than the Fire Engine Red from Faberdashery...

It's in your blood. Embrace it. Use it for good.
EDIT: Does that mean I can smooth prints by looking at them?
