Is polylactic acid (PLA) soluble in ethylacetate?
D- and L- polylactic acids come from both enantiomers of the monomeric lactic acids. 
There will be no difference in solubility between both polymers. 
Besides, lactic acid is normally produced by fermentation and the L- form is obtained, so the standard PLA used in 3D printing will be L- PLA. 

I have tested the solubility of a piece of PLA and it is not soluble in ethylacetate in one hour. 
It does even not seem to be attacked by it. 





However, when you rub a 3D printed piece with a paper soaked in ethylacetate, some polishing is attained. 



I make basically structural pieces, so I normally do not polish them and therefore I do not know if this is enough for your purpose.
