can you post the .stl file

like super glue fingerprint developing can heating the acetone help in the aerosolization for uniform coverage?

I made a test setup using a asparagus cooker.

the results were very shiny on the lower part of the model

(I used a big model)

this would work well for smaller models and elevated higher.

the advantage I saw was the vapor does not seem to leave the
milky discoloration direct painting of acetone leaves.
the disadvantage is for bigger models condensation seems to
be greater at the lower parts of the tank.

Maybe you should have got a rotisserie instead? ;)

What if you place a steel or iron bar in the bottom and a magnetically-driven fish tank filter motor underneath the pot? It will spin the bar and agitate the fumes so they fill the entire pot evenly.

Or use a fan to circulate the fumes trough the whole bottle.

Ooh, this is a great idea!

It actually made me go "oooooh!" out loud.

I'd be very interested to see some of the results of this process.

I find Makerbot's natural ABS reacts differently to acetone than their black ABS. After a little sandpaper, acetone gives me results like the picture below. Much discoloration, but barely any lines. Ready for painting.

I think you could call that a patina. It is presentable, at least from the pic.

Unfortunately our printer is down at the moment. As soon as it is back up I will print some models to take before/after pictures. The difference it makes is really incredible!
