How to finish printed objects

[old man emu]

If I dont have a hot bed, can I use the oven (I mean, the circle on the top... dont know the name in english) in a cooking pot? It has fan I can start to get the vapor out. I guess I could just place it at "high" (or medium?) and as soon as it boil stop it ? and then do step 4 ?

Please. please, please take note of the words I have written in BOLD lettering in my post. This process must not be carried out in a domestic space, unless you want to spend all of 2014 3D printing a new house and contents for you and your family.

By the way, the circular heated area on top of a cooking stove is called a hotplate.

(Please don't flame me for that last sentence)

emu is not kidding. acetone is about the most flammable substance there is. the vapor is explosive. just as explosive as propane or natural gas. you cannot use it anywhere near a spark or where a spark can occur. that means no electric motors unless they are rated explosion proof. no electrical switches, etc.

56c? wow I can't get my acetone hot enough to vapour unless I hit at least 100c on my hotbed, but then again that is a hotbed and not direct flame, for the amount of time I am actually doing it my acetone might not actually get above 80c, but as you mentioned open ignition source would scare me a bit, thats why I use my hotbed.

I've seen threads like these so many times. Using solvents in this way at home is just a bad idea. True, acetone is not as dangerous as some. However, IMHO, it is the gateway drug, so to speak. If this thread keeps going, it is only a matter of time before someone posts the link to the carburetor cleaner video where the guy is using beakers full of carb cleaner at home, on his desk, in his office, a closed window in the background, to soften his prints. Then we'll get the insanity of the solvents people are trying out to smooth PLA prints.

Just stop it already! Eventually, someone WILL get hurt.

I use my wife's nail polish remover with a paintbrush on my prints, I guess I better stop before I move onto the hard stuff. xd.

Well, people will try it anyway. By keeping this thread on we can discuss the worst case scenarios and make more people aware of possible hazard.

hotplate, thanks!

The oven fan is pretty much powerfull... smoke dosent even "out" of the area... wont it work with Acetone? Or I could use something to create a tunnel directly to the fan?

Atlast, I could do that here at my job, we are using that for the woodfloor.... it smell hawfull in this area!
