Thanks for the advice, I suspected as much on the material properties. Setting up a heated volume might be tricky.

The reason I was printing with ABS is because of its processing abilities with acetone. I am looking to make an airtight part. Even solid prints are not truely air tight. I know that I can smooth and fill gaps with acetone processing and ABS glue.

I can disolve PLA with MEK or Tetrahydrofuran, but can it be smoothed and also flow in a similar way to disolved ABS?
Does it become solid when the solvent dries?
Can I make a PLA "glue" like I can with ABS or perhaps use abs glue to make the object airtight?

I tried disolving PETG with choloroform. All I seem to get is a tacky mess. Perhaps MEK works better?
