The finishing off of an ABS print with a quick acetone vapour bath produces an even glossy surface if more time was spent filing and smoothing the surface the more professional the outcome, be careful not to leave the print in the vapour too long.
Comparison of a raw ABS print and one finished with an acetone vapour bath. I used a thin walled glass jar (Old Coffee pot would be ideal) thinner the glass quick the vapour forms. placed it on the heat bed of the printer (100-110C) and then placed the print in the vapour bath on top of an old jam jar lid you will see the ABS gloss over within a few minutes, remove as soon as you are happy with the results, be careful not to leave it in too long as the acetone will continue to dissolve the print for a while after taking it out of the bath. This needs to be left for a few hours to dry properly before handling else you will spoil the glossy finish.
