It can be applied with a paintbrush, and generally gives a decent smooth finish. I know there are many more technical solutions, but it depends on just how good you need that finish to be. I generally find this works OK for me, and is pretty hassle free without messing with heaters etc.

Total acetone vapor exposure time for the part is approximately 10 seconds.

Would something like this be ok if I only used one of the tiers?

Would it be ok to do a vapour bath of technical prints like the lawsy carriages? I'm in the middle of printing them right now but I'm worried that a vapour bath might ruin the details.

I do it outside and only put about 1/4" in the bottom.

Firstly, sorry if I posted this thread in the wrong section, I couldn't really find one that suited this topic.

I've been experimenting a bit with acetone finishing on the prints and I haven't really been that happy with the results. Most of the time I'm happy to leave the layer lines visible but there are some prints where you want to get it looking really good.

I've tried painting acetone straight on to the print but this leads to problems with leaving marks from the paintbrush. I've tried putting it in a jar with acetone-soaked paper towels for a few hours and that worked ok but sill left me wanting something more. I also tried heating up the print while it is suspended in a jar of acetone but it is hard to control how much smoothing you get on your print this way. After trying all of these, I switched to paint which is giving mixed results.

This made me think about other possible ways of finishing my prints using acetone and then I had an idea: put the acetone in a spray bottle and spray the mist onto the print. The mist will evaporate quickly hopefully leaving a shiny print underneath and there will be no marks as nothing is touching the plastic. I'll have to see whether the acetone will be ok in those spray bottle assemblies or if it will melt it away but I just thought it could be a good idea if anyone else wants to try it. I'll post some pictures tomorrow and see how it goes. And in the meantime, Happy Easter! big_smile

-Matt
