Is polylactic acid (PLA) soluble in ethylacetate? I'm searching for polylactic acid (that used in 3D printing) solvent, that is less toxic. It's used to postprocessing to polish object.

Dichloroethane is toxic, acetone and dichloromethane less, but enough. Tetrahydrofurane and chloroform usage is limited in Russia.

As I know there is D- and L- polylactic acid, I don't know what type is it, but can test using acetone.

Can I use ethylacetate for this purpose? Or there is another solvents?

Sorry about my english

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.
