I've used an old steamer pot (aka rice cooker) for boiling/condensing acetone vapor onto smaller ABS prints, with great success. Unfortunately, as the pieces become bigger, the vapor distribution in that pot doesn't allow for even "smoothing". Then, as pieces become even bigger, they don't even fit inside the pot at all. I was just curious if others have a workaround/hack method for this?
I have tried using a kitty litter bucket and a small fan (brushless is key!) to circulate, but it doesn't have the same effect. The model will absorb the acetone and make it all flimsy, without the excellent smoothing/glossy effect I've come to love with the heated method using an old steamer pot.
As an aside, for those concerned about using acetone for this, I really don't see the issue if used in a ventilated area (outdoors or in a big garage-type room). Don't stick your head or a lit match in a bucket full of acetone vapor, but short of that I'm not too concerned. If others have horror-stories, lessons learned, or tips on vapor smoothing large prints, I'd love to hear them. Thanks!
