DCM for Smoothing PLA prints - WTF is DCM?

Can anyone tell me what DCM is? I've heard that it can be used to smooth PLA prints. Is that true? Where can I get it, and what the heck is it?

Be careful with it. It's very nasty stuff.

THF would be preferable for smoothing PLA. It's evidently no more toxic than acetone. Hackaday has a good article on it.

I thought it was what you got in your pay packet on Friday when you were fired, DCM - Don't Come Monday.

:D
