A little whipe with acceton should burn through ABS quite easy right?
I'm a PLA user, so I'm not sure though.

I use neat acetone to improve the surface finish and remove the layer ridges at times. It works on ABS. However I have been surprised to find that this does not work on ABS+ which I purchased from ICE. Acetone does not seem to touch this.
As a rule, I print at 0.08 thickness with a top / bottom thickness of 1.2mm. 15 layers is usually enough to close any holes in the top, but I do occasionally get a spru type of mark where the nozzle finishes which makes it look like its been injection moulded.
There seem to be big holes in the head. What infill are you using? Perhaps a larger infill density will give it smaller holes to cover when closing?
I would suggest you should think splitting the model in two parts, and print them separately then glue together. You cad do either face-back or left-right/ If doing so, use also a generous brim to prevent warping, and cut it after gluing.
For the holes on top of the head, increase top solid layers and/or general infill. For 15% infill, use at least 6 top solid layers for 0.15 layer height, or 8-10 for 0.1 mm layer height.
Thanks for the advice guys. I wanted to try to print this monstrous thing in one go to proof my support settings, otherwise I would have split it through the mouth. Yeah, acetone can clean up a lot of things in ABS but the nose and chin are pretty brutal. I'm losing practically all of my detailing in those areas.
Nick - I used 25% infill to get the higher density algorithm with a layer height of 100 microns and a top/bottom thickness of .8mm.
It's too hot for the actual speed you're printing the top. Options:
- decrease temperature in general (this is useful for the other problematic areas)
- decrease minimum speed in cooling control

Re your secondary issue I have experienced that several times, actually probably most times but I rarely build organic models so I have never tried to fix it. I suspect the answer lies in one of, or both, using a different layer resolution(my gut tells me thinner but I am not actually sure) or increasing the bottom/top number of layers(which I feel is the better solution.)
