Great post!
I prefer the gloss look and I think you and Ian have inspired me to design an Arduino controlled acetone vapor finisher when I finish my current project.
Now thats something I would love to buy if it comes out well sir!
As for the finishing techniques, this is a wonderful tutorial! Hats off to you sir!
]]>The thread is very old, at least. The ideal base would be something like a bed of nails, where the print would be held up by a few points so pooling acetone could not reach it, and vapor can reach the bottom.
aka, "Pin Beds"... As extensively used in laser cutting etc to avoid flashbacks...
Easily home manufactured, but commercial ones are very nice with simple systems to enable you to add/remove pins as needed - the home versions tend to be nailed-into-base-board solutions

This would level it out and you wouldn't have to worry about the bolt heads used to raise it off the bottom of the heated acetone. Shouldn't be too expensive an addition to do this and the glass wouldn't be affected by the acetone.
Yes I wanted to use glass, but my 6x6 piece was too big to fit in the basket and I didn't find any glass circles... I almost stole the mirror from one of my gf's little handheld mirrors, but I didn't think she would appreciate it. I would still use the bolts because it allows the vapors to flow in that space... Plus the bolts come with the pot.
New here!
I am going to get the Presto 06003 Options Electric Multi-Cooker/Steamer at amazon.
Also a Darice 6 inch Round Mirror.
Is the bottom smaller than 6" (is that why the glass you have wouldn't fit)?
Thanks for sharing!
]]>What does this exactly mean, The 25% quality region?
As soon as the acetone is condensing on the lid, the 2 phase mixture is hitting and maybe even exceeding the 25% quality region.
Thanks

pics or it didn't happen... ;-)
Blue PLA. I couldn't get it to stay flat in ABS, and there is still a bit of warp.

Heart warming.
]]>Ya the glass plate works great and sits nicely on the rack. I just lift it out and set in the next batch on another plate.
Cheers

The cool thing is that if you watch the inside of the basket closely, you can see where the vapor is. It seems to condense on the metal and instantly evaporate in such away that you can see it rise up and slosh around, like watching water fill up a glass pitcher from the outside. I noticed that until it hit the lid, I didn't smell any acetone, but plenty of vapor seemed to be coming through once it did. You might be able to eyeball the level of the vapor and then kill the heat just before it reaches the top of the pot.
