Very clever! Wished I had known this some weeks earlier. But it´s ok; who knows if your print has been done in the same material as mine? Anyway, mine is already in the works.wedfactory wrote:Thomas, if you look at the first picture you can see the layering for the printer on the parts. The acetone vapor bath is what smoothed it out. Catch word being vapor. If I had dunked the print into acetone for two hours I would have ended up with a pile of ABS plastic at the bottom of the tub. Not good. What you will need is a good size tupperware tub (big enough for your print to fit in with a little room all the way around) with a top (helps if the tub is clear) and some paper towels, aluminum foil and acetone. Line the bottom and 3 sides of the tub with paper towels, pour in 4 oz of acetone. The paper towels will soak it all up and wick it up the sides some that is fine. next place the aluminum foil in the bottom of the tub. You do not want to set your print right into the acetone. Now place your on the aluminum foil and close the top. I set an alarm for 1 hour to go check on it. When it went off I checked on the status of the "vapor bath". Remember you got a clear tub and left one side uncovered so you can look in and not knock yourself out by opening the top. After one hour it had started to smooth out, so i set the timer of 30 minutes the next time. After that it still wasn't quite where I wanted it so I set the timer for 30 minutes again. this time when I came back it looked just about right. You will need to pull it out before you may think it is done. the ABS will still be soft when you pull it out and still take about 30 - 45 minutes to air out and it will still smooth out some more in that time.
I found this by googling "how to smooth 3d prints"
