After looking at it more closely I'm convinced that the printer came with white PLA.  It is more brittle than ABS and like n2ri said, the purity of white is well beyond the other white ABS I have.  I'm redoing the print tonight with the ABS cartridge I ordered and will try the smoothing again tomorrow.

AZERATE, I understand that I don't _have_ to do it... I just wanted to give it a shot.  I was confused why it didn't work because I assumed that the printer had come with ABS since I don't see where XYZPrinting sells PLA.

Light the end of the filament and smell it. ABS smells like burning plastic. PLA doesn't.

What is possible is that you have an early spool of the PLA that gonna be available for the Da Vinci - I assume they are going to use high temp PLA, as regular PLA will not feed unless you apply external cooling to the print head.

My XYZ filament melted easily in a acetone and vapor smoothing worked as expected. I have some other filament around that is also supposedly "ABS" that is almost immune to acetone, but it came from a different source than XYZ.

Where I slightly disagree is the finishing aspect. You don;t always need to "finish". Most smoothing can be accomplished by properly calibrating your printer. I do not own a Da Vinci, so I am also unfamiliar with software firmware settings....but I can tell you I think you are in need of calibrating your bed/X axis and calibrate your extruder.

Correct me if I am wrong.

ABS only needs a table spoon to make less than 20mins vapor then if you touch the print for like an hour its goo coated. need something like a rack with handle to lower and lift print out

What happened was really strange... I saw next to no smoothing at all on these parts.  I cooked almost half a quart of acetone and left them in there for nearly an hour and still nothing.  The parts should have been nothing but a puddle of white goo, but they were almost entirely intact.  The only real issue was when I tried to remove them and the bottom of the vase had stuck to the aluminum block and came off the rest of the print.  The surface was tacky, but not overly so.  This stuff was acting like it was partly PLA or something... really strange.

You can see in the pic that I put in another part made of dark ABS plastic from a Stratasys machine.  This part was in the crock pot only 4 minutes and it was starting to dissolve quite heavily.  Clearly the acetone vapors were strong as this thing got attacked really well.

Have any of you seen this?  These parts were with the sample white filament that came with the printer.  They claim it's ABS, but it sure doesn't act like it.
