Smoothing/Sanding Prints

Try printing with a few more perimeters.  I use at least 4 for most of my projects.  That gives me a bit more play for sanding. 

If you have extreme banding, look into removing the z backlash, but I seem to have no issues with a little backlash.  The banding does come off with a bit of work, but you don't have to remove all of it.  And don't blow off all of the plastic particles that you sand off.  It will melt with a little acetone to fill the gaps.  You may have to re-sand and apply the acetone again to get optimal results.

I don't use vapor often for my projects as I just sand, apply acetone slurry with a wooden single side q-tip and smooth it on, then let it dry.

You definitely need to hand sand first.  This will coarse finish the part and provide some smoothing to the surface.  As I said, the plastic particles from the sanding will provide filler for the valleys of the part when melting so leave some on.  It certainly helps a little.

Good Luck!

I have been turning up up half way. Leaving it in any less then 5 minutes seems to do nothing. That may be in part due to lack of hand sanding and I think the acetone I was using is real weak. I have some stronger acetone now (made for automobiles parts and not removing nail polish)

I also kept getting the part stuck to the bottom on the pan.

Yea, I have some better stuff now. I just need to give it a whirl along with the hand sanding.

Spray filler primer is your friend if you want to mould prints.
I'd also look into Bondo or 'builders bog' if your prints have errors or spots that need fixing.
