The above is a link to a time lapse video of a print I did over the weekend using PVA as support. (note the failure of the wipe tower in the background - need to make it bigger (>15mm) for high prints in the future).
One thing I have found so far is that there are definite design considerations for using dual extrusion support printing. The cost in $ is quite high both in the price of the filament (approx 4x) and in the volume used. I just used the default settings which did the job.
The job in the video used :
7.21 m PLA (57 grams) $ 1.94
11.92 m PVA (93 grams) $20.02
The model is 102 mm high and 100 mm in dia.
You can see the defect line where the wipe tower failed. There are several small defects where PVA strings were embeded in the print body and the dissolved out leaving cavities that will need post processing to fill.
otherwise quite happy with it. Lot's more to learn tho.
