There are a few main safety precautions you should consider. Make sure the area is well-ventilated. Acetone is flammable. A buildup of acetone gas could quickly get concentrated, meaning that a single spark could lead to disaster. Using a fan is good; angle it towards an open window. This is also to prevent exposure to acetone because of its toxicity. Be ...

Contrary to what the other answers suggest, the risk of fire is not that great. An acetone "explosion" is even more unlikely, since you need a ratio of 2.5%-12.8% acetone vapor to air for that: too much acetone (as would be the case inside of your smoothing vessel) and nothing happens, too little (as would be the case inside of a badly ventilated room) and ...

Rejuvenate is probably a bit of an exaggerated term. The number one adhesion suppressor is grease. The stuff that comes off of the fingers used to handle the sheet. Even if you are careful and only handle the sides, the grease will be carried to the center of the plate next time its cleaned with less aggressive solvents. Isopropyl alchohol does break down ...

Make sure that your acetone is actually acetone. According to the MSDS, ABSPlus-P430 is indeed "ABS resin" so acetone smoothing should work. Some companies sell confusingly-labeled products that might be mistaken for acetone, but are actually "eco-friendly" alternatives such as 2-butoxyethanol. While these alternatives work for some of the uses for which ...

No fire. Acetone is highly flammable. Avoid open flame, smoking, soldering etc. near acetone or acetone fumes. Be ready to fight a fire. Ventilate. Acetone is very volatile so the fumes will be everywhere in the room. While breathing them should not kill you, it is certainly not good for your health. It may cause drowsiness or dizziness. It is also a good ...

is it possible to smooth the surface of my print without loosing shape? That is by definition impossible. Smoothing the surface implies that the geometry is changed. Rather, the question is: how much does acetone smoothing change the shape, and is that change within the tolerances of your application? Acetone smoothing is a fickle process, and how (much) ...

The answer really depends on what you are using it for. Is it for dissolving ABS? A quick google search should show you what you want. The thread, Could you recommend me a suitable alternative to acetone as solvent?, has a good many points that are worth considering: For example, you may need to consider the Polarity Index Burdick & Jackson solvents ...

Ethanol (Ethyl Alcohol) should work just fine as long as it's around 80% or more. It's very similar to isopropanol as a cleaning solvent. What you're basically doing is removing any stray grease from the bed with a solvent that evaporates quickly. Methanol would also probably work. It's very poisonous though, and shouldn't come into contact with your skin, ...

Dish soap will remove grease very well. Once you rinse it with a moist sponge and dry with a clean cloth most residues will be gone.

I have used DCM (dichloromethane, or ethylene dichloride) to dissolve ABS (or cold-weld/glue parts together). From ABS wikipedia page: ABS polymers are resistant to aqueous acids, alkalis, concentrated hydrochloric and phosphoric acids, alcohols and animal, vegetable and mineral oils, but they are swollen by glacial acetic acid, carbon ...

Repeated exposure to acetone can lead to the skin becoming sensitised, which means that in the future it will become overly irritated at the slightest contact. On a more mundane note, it is an excellent degreaser and dries your skin something rotten. And then your fingertips can split and take days or weeks to close up, hurting in the meantime.
