How long did you leave it in there? What bed temp?

2 hours at 110 with very little acetone. (Was my first time)

When I bumped it up to 115 with a few table spoons of acetone it really kicked in. I think I had to heat up the glass jar a bit more. Which is why I did the 5c bump.

The key is to have it vape and then cool at the top of the jar and drip back down to the bottom.

I do it often.

I use a glass 20 gallon aquarium

I use one of these...

I put acetone in a little foil bowl on the plate.

I like to hang the parts from the lid with surgical tubing and alligator clips.

Bring the acetone to a rolling boil and it really fills the space with vapor rapidly.

3-5 minutes is all you need to really get a good smoothing effect. More than that and you can weaken the part significantly.

The parts need to dry/re-harden for 15-20 minutes, but they look great.

I use the identical jar you have used (Walmart) except I put a rubber silicon bead around it to keep in the vapor much longer.

Do you remember the temperature required to get the acetone to boil?

It's very low. My hotplate doesn't have temp readings, just 1-10 settings.

I believe it's in the neighborhood of 120-130F, but it has very high vapor pressure, so it doesn't take much above room temp for it to begin vaporizing.

The nice thing about it is that even though it boils at a low temp, it won't ignite until it gets to 400+F. You can really fill the chamber up quick, which makes for nice, smooth, and evenly bathed parts.

Just wanted to clarify here. You are referring to flash point and not vapor ignition point. The vapor will easily ignite at room temperature and the vapor is extremely flammable. And source of ignition at all will easily ignite the vapor even from a open vessel at room temp.

It will not flash (self ignite) until the temps you mention.

Important differences for those that may have felt it was not a fire hazard until high temps. It most definitely is.

Ah, yes, probably good to clarify that. In a closed tank without much oxygen, the risk of fire is minimized, but it is indeed extremely volatile and flammable.

Sounds good to me! I need to find some round glass that will fit inside for a flat surface. Also need to rig something up to lift the platform out when I'm done... Hmmmmm

I'm sorry I was far to busy staring at your avatar to hear a word you said.

You should have stopped while you were "a-head" short of the end.

They are less trouble that way too, LOL.

I have been away from my printer to try it again. I'm going to try round two Sunday afternoon. So post your results guys!

My lady will need a bath for sure when I'm done with her. Haha

Does anyone know how to get rid of all the little bumps when it starts the layers. I use kiss and not 100% sure with how the settings affect my prints.
