I am using a STRATASYS Fortus 250mc to 3D print some parts. I have read a lot on internet and also on some scientific literature that Acetone dissolves ABS and cold/hot vapor has been successfully used to smoothen the surfaces. But it doesn’t work for me.

I followed the instructions: soaking some papers with Acetone and putting the parts in a closed container with a fan for some time. But it had no effects. Then I tried dipping the parts in Acetone and I observed that they do not react to the substance at all!

Has anybody ever had a similar experience? Maybe ABSPlus-p430 is not soluble with Acetone? in that case what is a solvent for it?

I asked the same question here in SO: https://goo.gl/PjMn7C

I use eSun ABS+ and they have said it is much less reactive to acetone than regular ABS so maybe it is the same thing as you are seeing.
